ABSTRACT
Migratory birds are one of the living organisms that should be protected.These birds from northern hemisphere fly as far as 26 000 km a year across thecontinent for survival during the winter season. In addition, the migratory birds haveconsistently stopped by at Malaysia during the roosting season from November toMarch every year because they are attracted to the richness of Matang MangroveForest. The Department of Wildlife and National Parks (Kuala Gula) has carried outobservation on the arrival of these migratory birds. The process of data collectionhad started since 1993, however, there is still no analysis had been carried out on thetrend of bird migration for the past decade. The aim of this study is to develop a GISdatabase for the Department of Wildlife and National Parks (Kuala Gula) in order tofacilitate the study of biodiversity and sustainability of migratory birds. Meanwhile,the objectives of this study is to find out the requirement of Department of Wildlifeand National Park (Kuala Gula) ; build a GIS database for the migratory birds and
performed analysis on the observed data. The methodology flows from needassessment to data collection, database development and system integration, andfinally results and analysis on trend of bird migration, ecosystem properties,environment sensitivity analysis, morphometrics analysis and spatial statisticanalysis on the distribution of the migratory birds. Database for managing
biodiversity and sustainability of migratory birds has been developed using ArcView3.2, MapObject 2.0, Microsoft Visual Basic 6.0, AutoCadMap 2.0 and S-Plus 2000.The result is a migratory birds database with statistical results on the trend of birdmigration. From the results of trend of bird migration, the endangered species ofmigratory birds can be identified. Subsequently, from the endangered species beingclassified, it can provide guidelines and procedures in maintenance of the mangroveareas.

ABSTRAK
Perkembangan dalam bidang bioteknologi telah banyak membantu kerajaandalam usaha mengurangkan peratusan kepupusan hidupan terancam seperti burungmigrasi. Burung migrasi dari hemisfera utara terbang sejauh 26 000 km setiap tahunmerentasi kontinen semasa musim sejuk dari bulan November sehingga Mac. Burungmigrasi ini akan berhenti di Hutan Simpan Matang semasa musim berehat keranatertarik dengan kawasan paya bakau yang kaya dengan pelbagai jenis hidupan.Jabatan Perhilitan Kuala Gula telah menjalankan operasi pemerhatian dan
pengumpulan data semasa ketibaan burung migrasi ini, bermula sejak tahun 1993,namun masih tiada analisis pernah dijalankan untuk mengetahui haluan proses
penghijrahan burung migrasi di Malaysia.Tujuan kajian ini dijalankan adalah untukmembangunkan satu pangkalan data burung migrasi untuk Jabatan Perhilitan KualaGula supaya kajian terhadap kepelbagaian hidupan dan langkah pemuliharaan dapatdijalankan. Sementara itu, objektif kajian ini adalah untuk menjalankan kajiankeperluan pengguna, membangunkan satu pangkalan data GIS untuk burung migrasidan menjalankan analisis terhadap data burung migrasi. Metodologi kajian ini
bermula dari kajian keperluan pengguna iaitu Jabatan Perhilitan Kuala Gula,seterusnya pembangunan pangkalan data dan pengintegrasian sistem dan akhirnya
analisis terhadap haluan penghijrahan burung migrasi, kepekaaan persekitaran, datamorphometricsdan akhir sekali analisis statistik spatial terhadap penyebaran burungmigrasi ini. Satu pangkalan data untuk pengurusan dan pemulihan burung migrasitelah dibangunkan dengan menggunakan ArcView 3.2, MapObject 2.0, MicrosoftVisual Basic 6.0, Autocad Map 2.0 dan S-PLUS 2000. Hasil daripada tren
penghijrahan burung migrasi ini, burung yang diancam kepupusan, spesis baru,penghijrah tetap dan kitar hayat burung migrasi ini dapat diketahui. Hasil analisismenunjukkan burung yang diancaman kepupusan dapat dilindungi serta kawasanyang peka bagi burung migrasi ini perlu diberi perhatian sekiranya ada
pertembungan dengan projek pembangunan di sekitar kawasan tersebut.

CHAPTER 1
INTRODUCTION
1.1 Background of Study
The Department of Wildlife Peninsular Malaysia has been established to
give Malaysians an effective and capable service in conserving and managing
sustainable use of habitat and species diversity in Peninsular Malaysia. On the
other hand, the Department of Environment Malaysia plays an important role in
ensuring the uniqueness; diversity and quality of the environment are preservedtowards maintaining health, prosperity, security and well-being for the present and
the future. The Department of Environment has declared 5 June as World
Environment Day as a reminder for us to protect the environment.
Environment interacts with all kinds of living objects. The issues on
environment are a growing interest nowadays because it plays a vital role in the
continuity of human-being existence. There are a lot of environmental issuesnowadays such as pollution, deforestation, global warming, biodiversity and
sustainability and so forth.
Pollution is not a new issue to our society nowadays. The air, water and
sound pollution can create negative effects on human health such as food poisoning,
8/21/2019 Migracion Aves
24/255
2
asthma and respiratory infections such as bronchitis and pneumonia, headaches,
nausea and allergic reactions. Long-term health effects can include chronic
respiratory disease, lung cancer, heart disease, and even damage to the brain,
nerves, liver, or kidneys.
Development is the key to civilization and the only way for development is
deforestation. However, deforestation without careful planning will create a great
disaster to human being such as landslide, flood and global warming. The negative
effect of deforestation is getting more attention from our society and many
precautions had been taken to minimize the possibility of this occurrence such as
the enforcement of laws and forest reservation plannings.
The issue on biodiversity and sustainability is another issue being discussed
by our society. The risen in awareness is due to people realizing on the importance
of species dependency in this world. Every species living on the earth interacts
with one another in which the air, water and sunlight plays an important role as
external resources to make the cycle complete. Nobody can guarantee the
continuity of existence for every species including human beings. However, there
are numerous precautions that can be taken to prolong the extinction period of every
species. For example, careful management on the conservation and protection of
the endangered species will definitely help to decrease the percentage of extinction.
The goals of sustainable development in Malaysia are not being met, partly
because of the lack of access to advanced technology for environmental monitoring
as well as for biodiversity and sustainability management practices. Geographic
Information Systems (GIS) is a unique and important tool for monitoring the
degradation of tropical ecosystems.

1.1.1 Issues on Biodiversity and Sustainability
Biological diversity means the full range of variety and variability within
and among living organisms and the ecological complexes in which they occur. In
addition, biological diversity encompasses community diversity, species diversity,
genetic diversity, and ecosystem diversity. Life comes in an almost infinite variety
of fascinating and enchanting forms, from microscopically small unicellular species
to giant whales and elephants. In turn, species are formed by different kinds of
populations, these by different kind of individuals and these by different types of
organs, tissues, cell, and genes.
Biodiversity is therefore not an entity, a resource, but a property, a
characteristic of nature. Species, populations, certain kinds of tissues are
resources, but not their diversity as such. But diversity is a defining characteristic
of life. Without diversity life is not conceivable, just like a ball without roundness
is not conceivable, or a diamond without hardness is not a diamond. There is so
much diversity, and it takes so many forms we ask in disbelief, where does this
diversity come from? Fundamentally it derives from the properties of a variety of
macromolecules, most notably DNA and proteins. Their characteristics make
biodiversity possible. Biodiversity underpins the processes that make life possible.
Healthy ecosystems are necessary for maintaining and regulating: atmospheric
quality, climate, fresh water, marine productivity, soil formation, cycling of
nutrients and waste disposal (Reid and Laird, 1993).
Malaysia is the world's 14th ranking mega-diversity country as stated in a
report by Association of Southeast Asian Nation. To give one an idea how
valuable biodiversity is, experts have estimated that more than 40% of the world's
economy and 80% of the needs of the world's poor are taken from biodiversity
(Iluminado, 2003).

In addition, Malaysia has 2.12 million hectres of national and state parks,
wildlife sanctuaries, turtle sanctuaries and wildlife reserves. Some 3.43 million
hectres are also protected as water catchments area (Sorensen, 2002).
Recently there is a regional conference on Biological Diversity (CBD) that
took place from 9-20 February 2004, at the Putra World Trade Centre in Kuala
Lumpur, Malaysia. Over 2,300 participants attended, representing 161
governments, as well as UN agencies, non-governmental organizations (NGOs),
intergovernmental organizations (IGOs), indigenous and local communities,
academia and industry. The meeting had came out with a decision which had
adopted 33 decision on biodiversity and tourism; monitoring and indicators; the
ecosystem approach; biodiversity and climate change; sustainable use; invasive
alien species (IAS); the Strategic Plan; mountain biodiversity; inland water
ecosystems; marine and coastal biodiversity; protected areas (PAs); access and
benefit-sharing (ABS); technology transfer and cooperation; Article 8(j) (traditional
knowledge); incentive measures; communication, education and public awareness
(CEPA); scientific and technical cooperation and the clearing-house mechanism(CHM); financial resources and mechanism; and national reporting.( Damodaran,
2004)
In April 2003, Wetlands International commenced on a two-year
conservation project at Kuala Gula wetlands, with funding from Danish
International Development Assistance (DANIDA) (Asian Waterbird Census 1997-
2001).
An article taken from the Star Newspaper (5 March 2005) has stated that
nine companies would be charged in the court in connection with the degradation
around the Bukit Cahaya Seri Alam Agriculture Park. Besides, the Selangor
Government has also announced that local councils would no longer have the
8/21/2019 Migracion Aves
27/255
5
power to approve any development projects near by environment sensitive places.
Menteri Besar Datuk Seri Dr Mohamad Khir Toyo was ordered to take immediate
action by Prime Minister Datuk Seri Abdullah Ahmad Badawi, who expressed
outrage over the degradation of Bukit Cahaya after seeing the destruction from the
air in a 45-minute helicopter ride.
The main causes for loss of biodiversity in Malaysia are habitat destruction,
over harvesting and pollution. As of early 1995, the National Policy on Biological
Diversity was in the final phase of formulation before being endorsed by the
Cabinet. The aim of this national strategy is to maintain plants and animals in their
original habitats as well as outside of their original habitats in facilities such as
botanical gardens. The purpose is to ensure long-term food security and
preservation of the unique biological heritage of Malaysia (Natural Resources
Aspect of Sustainable Development in Malaysia).
1.1.2 Genetic, Species and Ecosystem Diversity
Genetic diversityis the combination of different genes found
within a population of a single species, and the pattern of
variation found within different populations of the same species.
Species diversityis the variety and abundance of different types
of organisms, which inhabit an area.
Ecosystem diversityencompasses the variety of habitats that
occur within a region, or the mosaic of patches found within a

1.1.3 Endangered Species of Birds
Danish Co-operation for Environment and Development chief technical
adviser Kim Worm Sorensen said the rate of extinction today is six species per
hour. In rainforests, the extinction rate is 50,000 species a year (Sorensen, 2002).
Meanwhile, an article in the Star newspaper stated that forty species are globally
threatened in Malaysia. This places Malaysia on the 10th spot on the list of Asian
countries with the most number of bird species at risk of extinction. Of the 40
species, three are considered critically endangered, four are endangered and 33 are
vulnerable. During the last century, some species of birds have gone extinct, such
as the green peafowl in Peninsular Malaysia and the white-shouldered ibis in
Sarawak (Malaysia's Avifauna - The endangered ones).
Although biodiversity loss primarily centers upon the destruction of entire
ecosystems, some species are more at risk, and more critically endangered than
others. The biological value of some is not immediately obvious, but each has its
own unique place in the ecosystem, and the depletion or loss of one species can
have unexpected and devastating knock-on effects on others.
There are a few local birds, which are under the category of endangered
species such as the Milky Stork and Lesser Adjucant. It is recorded that about 5500
Milky Stork left in the world and 100 left in Malaysia. The three critically
endangered species are the Christmas Island frigatebird, White-rumped vulture;
Chinese crested tern and Silvery wood pigeon. The four endangered ones are
Storms stork, Nordmanns greenshank, Bornean peacock-pheasant and white-
winged duck.
Malaysia has important populations of many threatened rainforest birds.
These include three species endemic to the peninsula: the mountain peacock-
8/21/2019 Migracion Aves

pheasant, Malayan whistling-thrush and the Malaysian Peacock-pheasant. The
coastal and inland wetlands host globally threatened resident and migratory water
birds such as the milky stork, lesser adjutant, and storms stork, spotted greenshank,
spoon-billed sandpiper and Chinese egret (Sim, 2003.
1.1.4 The concept of Ecosystem and Environmental Protection
A simple definition by Transley (1935), ecosystem is an assemblage ofbiotic and abiotic components making up an interdependent system. Abstraction of
nature such as the ecosystem concept can be used in both a general way and a local,
specific way. For example, one can discuss the tall grass prairie ecosystem as an
abstract representation of an ecosystem type that once covered much of the former
Prairie Peninsula. But one can also use the ecosystem concept to describe, analyze,
and predict behavior of a specific representation of a general ecosystem type, such
as prairie relict consisting of only a few acres along a railroad in Rowa (Reiners,
1995).
1.1.4.1Ecosystem Properties
When analyzing and modeling environmental systems at the ecosystem
level, it is useful to focus on certain structural and functional properties. A list of
very general ecosystem properties, each of which can be subdivided for more detail
and definition of particular ecosystem is as follows:
Climate at appropriate space and time scales
Soils
8/21/2019 Migracion Aves
30/255
8
Water regime (hydrology, chemistry)
Species composition
Physical structures (dimensions, distribution of live and dead
biomass, photosynthetic area)
System energetic (physical energy budgets, biological energy
flows)
Nutrient budgets and cycles
Regulatory processes
Topological relationships (influences from neighboring
ecosystem)
(Reiners ,1995)
The ecosystem in Kuala Gula is the main attraction for tourism. The
richness of mangrove has attracted the migratory birds to stop by and find their food
there. The mangrove contains of many living organism such as birds, fish,
mollusks, crustaceans, frog, worms, prawn, insects, grass and so forth interacts with
one another. Air, water and sunlight play an essential role in completing the circles
of ecosystem.
1.1.5 Environment Protection
Efforts to draft legislation on the protection of wildlife in PeninsularMalaysia dated as far back as 1869. The first legislation was the Straits Settlement
Ordinance No. 3 of 1894, which covers only a few species. 1955 was a historical
year for the Wildlife Department as the Wild Animals and Birds Protection
Ordinance No.2 of 1955 was passed. In 1972, the Wildlife Protection Act No. 76 of
1972 was drafted and was subsequently passed by the Parliament and obtained
Royal Approval on 28 April 1972. The Act was published and gazetted on 4 May
8/21/2019 Migracion Aves
31/255
9
1972.
With the Wildlife Protection Act No. 76 of 1972, the Wild Animals and
Birds Protection Ordinance No.2 of 1955 were abolished. Wildlife conservation
activities in Peninsular Malaysia come under the administration of the Federal
Government. The Wildlife Department was later known as the Department of
Wildlife and National Park or PERHILITAN in short (Department of Wildlife and
National Parks).
1.1.6 Kuala Gula The Bird Sanctuary
Kuala Gula wetlands are located in the district of Kerian, about 45 km from
Taiping, in the state of Perak. Kuala Gula is located towards the north of the
Matang Mangrove Forest Reserve. Matang is the single largest tract of mangrove
forest in Peninsular Malaysia. It covers an area of 40,000 ha. Matang was firstprotected in 1906 and is rated as the best managed mangrove forests in the world.
Kuala Gula and its associated wetlands (mudflats, mangroves, rivers and
estuaries) extend to approximately 12,000 ha. It is an important area for fisheries as
a majority of the local community at Kuala Gula is involved in this thriving
business. There are about 600 families involved in the harvesting of fish, shrimp
and shellfish, cockle farming, aquaculture as well as in the processing of shrimp andfish products. The mangrove is a rich breeding ground for various aquatic lives,
including shrimps, cockles and mud crabs.
Kuala Gula mangroves are known best as a roosting and feeding site for
migratory water birds. 48 migratory water birds including the Little EgretEgretta
8/21/2019 Migracion Aves
32/255
10
garzettaand Great Egret Casmerodius albus, and many waders such as the
Common Redshank Tringa totanus, Common Greenshank Tringa nebularia,
Eurasian CurlewNemenius arquata, Common SandpiperActitis hypoleucosand
Mongolian Plover Charadrius mongolus, as well as threatened resident water birds
such as the Lesser AdjutantLeptoptilos javanicus and the endangered Milky Stork
Mycteria cinereahas been recorded in Kuala Gula. These resident birds are nesting
in this wetland. Birds of prey are also very common here, especially the Brahminy
Kite,Haliastur indusand Crested-serpent Eagle Spilornis cheela.
The Department of Wildlife and National Parks (PERHILITAN) have
established Kuala Gula as a bird sanctuary since 1970. These water birds migrate
from the Northern to Southern Hemisphere especially from Siberia and Mongolia
and stopover at Kuala Gula for feeding at the mudflats and mangrove forests in the
wintering months. Every year approximately 5,000 visitors came to Kuala Gula for
bird watching. Thousands of birds can be seen in Kuala Gula wetlands especially
during the migratory and wintering season from September to April of the
following year. During non-migratory season, you can see the resident water birdssuch as the Lesser Adjutant and Milky Stork.
Besides that, Kuala Gula lies close to two sites (Pulau Kelumpang and Pulau
Trong Bird Sanctuary) that have been reserved as Bird Sanctuaries within the
Matang Mangrove Forest Reserve. Both are island reserves that harbour probably
the only viable population of the globally endangered Milky Storks in Malaysia. It
is recorded about 5,550 left in the world and 100 left in Malaysia, and in a recentsurvey the wildlife officer of Kuala Gula Office observed 10 Milky Storks in Pulau
Kelumpang. Kuala Gula is also a wildlife sanctuary. Mammals are also found in
the mudflats and forest area. They are the Smooth Otter Lutra perspicillata,
Silvered-leaf Monkey Trachypithecus cristatus, Long-tailed Macaque Macaca
fascicularis and Ridgeback Dolphin (Sim, 2003).

1.2 Problem Statement
The migratory birds from northern hemisphere stop by in Malaysia before
continuing their journey to other countries such as Australia during roosting season
from November to March every year. For instance, from a group of migratory
birds, there will be a few species which are categorized under endangered species
due to the low rate of number found compared to other species. These endangered
species need to be protected from any further harm to minimize the possibility of
extinction.
Department of Wildlife and National Parks Malaysia (DWNPM) has
conducted an early study on migratory birds in Matang Mangrove Forest in a joint
venture research program with the Japan Wildlife Research Center (JWRC). The
avifauna population was studied using three methods namely; direct observation,
mist netting, and line transect surveys by scientists from both organizations in 1993-
1995.
Although authority in Department of Wildlife and National Park, Kuala
Gula still carry out field observation to collect the data of migratory birds till now,
no analysis has been carried out on the data. In addition, there is still no GIS
implementation in managing the data of migratory birds. As a matter of fact, the
trend of bird migration in Malaysia has not been discovered. The statistical analysis
on the endangered species of migratory birds for the last decade can give us an idea
on how the trend of bird migration has been changed.
Geographical Information System is a computer system to manage the
process and to analyze the geographical referenced data. There are some popular
analysis provided by the GIS softwares namely, spatial analysis, 3D analysis and
network analysis. Spatial analysis such overlay can be used to obtain an output that
8/21/2019 Migracion Aves
34/255
12
fulfills the criteria of two layers. This analysis can be used to find out the sensitive
area for the migratory birds.
In addition, GIS provides the function of spatial and attribute linking. By
using GIS, the data from field observation can be linked to the map of the study
area. GIS plays important roles in managing the sustainability of the mangroves
area, which indirectly brightens up the future of the migratory birds to Malaysia.
Besides the sustainability purpose, Kuala Gula the bird sanctuary has
attracted thousands of tourists every year just to have a glance of the spectacular
view of those colourful migratory birds. For this reason alone, the need to protect
the sensitive area for the migratory birds is undeniably significant to promote the
tourism in Malaysia.
1.3 Aim and Objectives
The aim of this study is to develop a GIS database for Department of
Wildlife and National Park, Kuala Gula in order to facilitate the study of the
migratory birds.
Meanwhile the objectives of the study are listed as follows;
To assess the need of the Department of Wildlife and National Park,
Kuala Gula for database development
To build a GIS database for the migratory birds
To perform analysis using;
Trend of bird migration

1.5 Scope of study
The scope of this study is basically related to software, data types, analysis
to be performed and the designation of user interface. Several software being used
which includes ArcView 3.2, MapObject 2.0, Microsoft Visual Basic 6.0, AutoCad
Map 2.0 and S-Plus 2000.
The most important data for this study is the distribution of migratory
birds within the study area from 1993 to 2004. The limitation for this data is the
total number of migratory birds being recorded is just estimation because there is no
consistency in date and time for observation. The data from 1998 and 2001 are not
available; therefore they are excluded from the analysis because no fieldwork was
carried out during these four years.
On top of that, morphometrics (measurement taken from a bird structure)
data of the migratory birds is needed for this study to find out the age of the
migratory birds to Kuala Gula wetlands. The availability of the data is from 1992
to1995 and 2002 to 2004.
The cadastral lot for Kuala Gula wetlands is very important for the analysis
on environment sensitivy in study area. Meanwhile, as an additional knowledge,
the list of the migratory birds together with their picture is important for
identification purposes.
Three main analyses for this study include: trend of bird migration,
environment sensitivity analysis and spatial statistic on the distribution of migratory
birds. All three analyses require the use of GIS functionalities in order to obtain the
results. Meanwhile, an additional analysis on the morphometrics data for the
migratory birds will be carried out as an additional knowledge on the shorebird
8/21/2019 Migracion Aves
37/255
15
banding in Asia.
Finally, a friendly user-interface has been created for the authority in
Department of Wildlife and National Park, Kuala Gula.
1.6 Importance of Study
This study is of paramount important to find out the location of the
migratory birds. In addition, this study can provide the information about the trend
of bird migration in Malaysia. From the database being created for the distribution
of migratory birds from 1993 to 2004, the new species, endangered species and the
constant visitor of migratory birds to Kuala Gula wetlands can be identified. The
total number of migratory birds being discovered every year would be summed up
so that comparison can be made for a period of a decade. This analysis is very
important to explain whether the ecosystem in Kuala Gula wetlands is still well-preserved.
From the migratory birds database, the date of arrival for the species of
migratory birds has been jotted down in the database. From there, a temporal
analysis can be performed on the seasonal arrival of these migratory birds. The
results on this analysis can provide a valuable information for bird lovers in
Malaysia so that they can carry out bird watching activities at the peak season of thearrival of these migratory birds.
Environmental sensitivity analysis is utmost important to find out the
sensitive areas for the migratory birds. These sensitive areas for the migratory birds
need to be protected in order to prolong the extinction period. GIS operation such as
8/21/2019 Migracion Aves
38/255
16
buffer and overlay is performed so that the government can carry out
conservation activities affectively.
Apart from that, spatial statistic on the distribution of migratory birds can
provide a result concerning the spatial patterns on the distribution of migratory
birds. There are three types of spatial patterns namely, clustered, dispersed and
random. The nature of spatial autocorrelated data that is the data that is not random
in space. This result is important to provide an indication whether the places of the
distribution of migratory birds share the similar characteristic.
Finally, this study is significant towards sustaining the migratory birds to
Malaysia. This is to ensure the migratory birds from northern hemisphere will
continue to visit Kuala Gula and the surrounding mangrove areas in the future so
that the ecosystem in the study area can be preserved.
1.7 Related Research
There are numerous related studies on migratory birds and trend of bird
migration. The pioneer study for migratory birds in Malaysia was conducted
between September 1993 to January 1995 by the Department of Wildlife and
National Parks (DWNP) and the Japan Wildlife Research Center (JWRC) in the
joint venture research program on the biodiversity of Wetland in Malaysia.Scientists from both organizations also conducted studies on migratory birds
population during their annual migration. The studies on avifauna were conducted
at various locations in the Matang mangrove forest reserve during the three years
study period. Bird observation was conducted along the rivers especially Sungai
Gula, Sungai Selinsing and Sungai Kelumpang. The avifauna population was
studied using three methods namely; direct observation, mist netting, and the line
8/21/2019 Migracion Aves
39/255
17
transect surveys. The study was conducted from 15 September to 7 October 1993
for the first phase, from 7 to 17 for the second phase and from 18 to 21 January
1995 for the third phase. A total of 78 species from 33 families were recorded
during the first phase of study, 75 species from 36 families in the second phase, and
only 37 species from the third phase respectively (Satoo, 1995).
A study by Oliver in 1999 was to design a GIS database to produce an ESI
map to determine the environmental sensitivity areas when oil spill occurs. It is
also a decision making tool for the management in prevention and clean up before
or after the oil spill occurs.
An extension from the study by Oliver, a team from Universiti Teknologi
Malaysia (Ibrahim Busu, Norkhair Ibrahim, Ghazali Desa and Surya Asnarius) with
a cooperation of the Japanese Wildlife Research Center (JWRC) has produced an
ESI map for oil spills. This study has been conducted to develop the ESI maps
based on standard Sensitivity Index, which is produced by the NOAA and Coastal
Resources for East Coast Peninsular Malaysia. The primary objectives of this study
were to design and develop ESI database, to design and produced ESI maps for
study area using GIS technology and to analyze the advantages of using GIS
approach to produce ESI maps as compared to conventional method. The final
results of this study include the ESI system and ESI maps. The maps produced are
divided into three major types, which is Sensitivity Index for the Shoreline,
Biological Resources and Human-Use Resources.
Besides that, North American Breeding Bird Survey had carried out a
research on trend of bird migration in America. The aim of the research is to find
out the change of population of local and migratory birds. Of the 245 species
considered, 130 have negative trend estimates, 57 of which exhibit significant
declines. Species with negative trend estimates are found in all families, but they
8/21/2019 Migracion Aves
40/255
18
are especially prevalent among the mimids (mockingbirds and thrashers) and
sparrows. A total of 115 species exhibit positive trends, 44 of which are significant
increases. Flycatchers and warblers have the largest proportions of species with
increasing populations (Peterjohn, et. al, 1992).
Futhermore, Debbie Badzinski (2003) has carried out a research on trend of
bird migration for 63 species of migrant birds, and eight species of irruptive or
partial migrants at Thunder Cape Bird Observatory (TCBO) from 1995-2002.
These indices were calculated from daily estimated totals of birds passing through
the designated area. This result had came out with three conclusions, which were
summarized as follows;
i) Spring population trends (1995-2002). Based on spring population
trends, 81% (35/43) of species have declined and only 19% have
increased at TCBO between 1995-2002.
ii) Fall population trends(1995-2002). The majority of fall migrants at
TCBO also had decreasing population trends from 1995-2002. Seventy-three percent (45/62) of fall migrants declined, and only 27% increased
(17/62).
iii) Combined spring/fall population trends(1995-2002). Combined
spring/fall trends were calculated for 39 species at TCBO. Eighty-one
percent (31/38) of species at TCBO declined and only 18% (7/38) of
species had positive trends from 1995-2002.

CHAPTER 2
LITERATURE REVIEW
2.1 Introduction
Literature review for this chapter is very useful for identifying researches
that had been carried out on bird migration and thus can be used as guidelines for
this research. The author carried out this task for about three month by interviewing
the authority in Department of Wildlife and National Park, Kuala Gula, Perak and
by reading some relevant books/articles/ newspaper/journal/internet resources etc.
The content of this chapter gives a brief explanation on the study area (Matang
Mangrove Forest), biodiversity and sustainability issues in Malaysia, implementing
Geographical Information System (GIS) for the better management of biodiversity
and sustainability and last but not the least researches that had been carried out by
local and foreign researchers on the issue of biodiversity and sustainability of bird
migration.
2.2 Mangrove forest in the world and wetlands in Malaysia
According to Odam (1970), wetlands are considered as priceless area for
human, but the wetlands and mud flat area are actually rich diversity area as a
8/21/2019 Migracion Aves
43/255
21
connection area of land ecosystem and aquatic. According to Whittaker (1975),
wetlands occupy 3.5% of the world because net primary production of the wetland
ecosystem is 3 times higher than average ones. People living near the wetlands
areas can be used food as resources such as shellfish, crustacean; fishes and so on
depend on the high productivity of the area. Also, they use the plants resource such
as nipa and mangrove tree for the architecture material and firewood. However,
converting wetlands into agriculture land or residential areas by large scale by
progress of large-scale earth technique used mechanical power. The wetlands in
South East Asia also are not an exception and the conversion from the wetlands to
other types of land cover such as plantation areas; fishponds and residential areasare mushrooming. According to Kunihuda (1994), the mangrove areas of each
country decreased half of the primary area in last two decades in Thailand,
Malaysia, Myanmar and Bangladesh (Satoo, 1995).
2.2.1 Classification of Wetlands and Mangrove Forest
Whittaker (1975) has classified ecosystem and net production of the world
and calculated of the wetland area about 200 million km2except tundra area.
(Satoo, 1995). Table 2.1 shows classification of the wetlands.

2.2.2 Geo-historical change of wetlands in the glacier age
Geo-historical change of the wetlands in the glacier age Peninsula Malaysia
is mainly researched through the study on Sunda Sea. Furukawa (1992) stated that
sea level of the Sunda Sea dropped 72 meters in the last glacier age and major part
of continental shelf around Peninsula Malaysia were land area. Traces of major
rivers in the glacier age are found in the continental shelf area around the Peninsula.
Sea level rise after the last glacier age and the Sunda Sea was formed.
Transgression with rise of sea level in 2 to 3 meters occurred in 6000 years ago in
the Sunda Sea. Transgression and regression caused large mudflat and fresh water
swamp around coast area of the Sunda Sea. Continental slope is so gentle that little
down of sea level lead to large mudflats along the coast. Large mud flats were
made in the regression period in the Holocene epoch. Front line of the mud flats
followed the regression sea level, and the recent wetlands along the coast area were
8/21/2019 Migracion Aves
47/255
25
made in Peninsula Malaysia The Matang Mangrove area might also built after those
geo-historical changes (Satoo, 1995).
2.2.3 General Description of Matang Mangrove Forest
Matang mangrove forest is located on the coast along the straits of Malacca
in western area of Taiping, Perak. The mangrove forest spread in estuary area of
the Gula, Trong and Sangga Besar rivers. The mangrove forest stretches about the40 km for the north and south, and 11 km for east and west and covers a land area
approximately 40, 711 hectare. Although there are small fisherman villages such as
Kuala Gula, and Port Weld on the coast and rafts for fish farming are scattered in
the rivers, major part of the area is managed as production forest or reserve.
The Matang mangrove came under forest management from beginning of
20
th
century and logging and charcoal production were continued undermanagement plans of Perak State Forestry Department. The traditional
management plan for the mangrove forest over a period of thirty years, which was
framed in the colonial era, is applied now with some revision. Expected yield of
mangrove trees for charcoal processing is 177 tones per hectare and 146 tones per
hectare for firewood (Perak State Forestry Department, 1981). The mangrove forest
area is divided into productive forest and unproductive area. Table 2.4 shows the
area of the productive and the unproductive forest in three divisions.

2.3 The Wetland International
Wetlands International is a world organization to manage the wetlands
around the world. This organization was formerly known as the International
Waterfowl and Wetlands Research Bureau (IWRB). Wetland International has
coordinated the Asia-Pacific Migratory Water bird Conservation Committee that
implements the Asia-Pacific Migratory Water bird Conservation Strategy.
The first strategy was carried out between 1996 and 2000, actively
supported by the governments of Australia and Japan. The strategy has been highly
successful in promoting international activity related to flyway co-operation for
waterbirds. The strategy has helped in the establishment of three networks of
internationally important sites:
East Asian-Australasian Shorebird Site Network (1996)
North East Asian Crane Site Network (1997) East Asian Anatidae Site Network (1999) which focuses on promoting
conservation of important wetlands in the breeding grounds of the waterbird
family (that covers swans, geese and ducks) in the northern hemisphere.
The strategy has also raised awareness of the need to conserve migratory
waterbirds and their habitats in the Asia-Pacific flyways through a series of
initiatives implemented at local and international levels.
According to the Wetlands International report, Numbers and distribution
of water birds and wetlands in the Asia-Pacific region Results of the Asian
Waterbird Census: 1997-2001, more than 5, 700 sites from 26 countries have been
8/21/2019 Migracion Aves
51/255
29
counted at least once, since AWCs inception on the Indian sub-continent 17 years
ago.
The five-year Census surveyed 1, 392 sites in 22 countries at least once.
This included 61 wetlands of international importance or popularly known as
Ramsar sites, 32 Migratory Waterbird Network Sites in the East Asian-Australasian
Flyway and 43 Important Bird Areas, with the highest count of 4, 571, 522 birds
from 770 sites registered in 2001. The Census reported that 82 sites in ten
countries supported more than 20, 000 birds each and of the 82, 22 are Ramsar
sites. A total of 291 species of waterbirds and 15 species of wetland-dependent
raptors were recorded. 37 species were recognised as globally threatened: two
critically endangered, eleven endangered and 24 vulnerable (The Star, 15th
June
2004).
2.4 Birds in Matang Mangrove Reserve
The mangrove forest of Matang is locally as well as internationally known
for its wide arrays of resident and waterbirds. Its wetland habitats and extensive
mudflats are rich in various forms of marine fauna, which are a constant source of
food for many species of migratory and resident waterbirds. From the total of 650
species of birds recorded in Peninsular Malaysia, more than 195 species can be
found in Matang, of which 48 are migratory birds.
Matang also has a large population of migratory coastal waterbirds believe
to be anywhere in the range of 75, 000 to 180, 000 during the annual cold wintering
months up to North from July to April. They are believed to visit the same site
every year, provided their habitats are not disturbed. Some of the migratory birds
came as far as Northern Russia and hemisphere making a stopover in China then to
8/21/2019 Migracion Aves
52/255
30
Matang for resting and refueling before continuing their journey to Indonesia and
Australia. The most common of the migratory waterbirds are Common Redshank,
Mongolian Plover, Black-tailed Godwit, Terek Sandpiper, Curlew Greenshank,
Bar-tailed Godwit and Grey Plover.
Matang also have a large variety of mangrove forest birds. Among the most
commonly observed are the Stork-billed Kingfisher and the Collared Kingfisher.
The majestic Brahminy Kite (Haliastur Indus) is a common sight anywhere in
Matang.
The Mangrove Forest of Matang is also a stopover for many migratory
forest birds. They would stop in Matang before flying towards lowland and hill
forest towards the mainland. In addition, many species of colourful local land birds
can be seen in the forest of Matang the whole year round. They include many
species of Sunbird, Flowerpecker, Flycatcher, Kingfisher, Myna and Woodpecker
(Noramly, 2002).
2.5 Early ideas about bird migration
The migrations of birds have probably attracted the attention and aroused
the imagination of humans since the African genesis. Recorded observations on the
subject date back nearly 3, 000 years to the times of Hesiod, Homer, Herodotus, and
Aristotle. In the Bible, there are several references to the periodic movements of
birds, as in the Book of Job (39:26), where the inquiry is made: "Doth the hawk fly
by Thy wisdom and stretch her wings toward the south?" The author of Jeremiah
(8:7) wrote: "The stork in the heavens know her appointed time; and the turtledove,
and the crane, and the swallow, observe the time of their coming." The flight of
Migratory Quail that saved the Israelites from starvation in their wanderings
8/21/2019 Migracion Aves
53/255
31
through the Sinai wilderness is now recognized as a vast migration between their
breeding grounds in Eastern Europe and western Asia and their winter home in
Africa.
Aristotle, naturalist and philosopher of ancient Greece, was one of the first
observers whose writings are known to discuss the subject of bird migration. He
noted cranes traveled from the steppes of Scythia to the marshes at the headwaters
of the Nile, and pelicans, geese, swans, rails, doves, and many other birds likewise
passed to warmer regions to spend the winter. Pliny the Elder, a Roman naturalist,
in his "Historic Naturalist, " repeated much of what Aristotle had written on
migration and added comments of his own concerning the movements of European
species of starlings, thrushes, and blackbirds.
Aristotle also must be credited with the origin of some superstitious beliefs
that persisted for several centuries. One of these, that birds hibernated, became so
firmly rooted that the eminent nineteenth century American ornithologist, Dr.
Elliottq Coues, listed in 1878 the titles of no less than 182 papers dealing with the
hibernation of swallows. The students of Aristotle believed the disappearance of
many species of birds in the fall was accounted for by their passing into a torpid
state where they remained during the cold season, hidden in hollow trees, eaves, or
in the mud of marshes. Aristotle ascribed hibernation not only to swallows, but also
to storks, kites, and doves.
Some early naturalists wrote fantastic accounts of flocks of swallows
allegedly seen congregating in marshes until their accumulated weight bent the
reeds into the water, submerging the birds, which apparently then settled down for a
long winter's nap. It was even recorded that when fishermen in northern waters
drew up their nets they sometimes had a mixed catch of fish and hibernating
swallows. Olaus Magnus, Archbishop of Upsala, published a work in 1555 entitled
8/21/2019 Migracion Aves
54/255
32
"Historia de Gentibus Septentrionalis et Natura" observing that if swallows so
caught were taken into a warm room they would soon begin to fly about but would
live only a short time.
The idea of hibernation as a regular method of spending the winter is no
longer broadly accepted for birds, although the Common Poorwill is a possible
exception. Many species, however, such as chickadees, swallows, hummingbirds,
swifts, and nightjars regularly go into torpor under cold stress on winter nights but
also even during the breeding seasons.
Aristotle also was the originator of the theory of transmutation, the seasonal
change of one species into another. Frequently one species would arrive from the
north just as another species departed for more southerly latitudes. From this he
reasoned the two different species were actually one and assumed different
plumages to correspond to the summer and winter seasons.
Probably the most remarkable theory advanced to account for migration is
contained in a pamphlet titled, "An Essay toward the Probable Solution of this
Question: Whence come the Stork and the Turtledove, the Crane, and the Swallow,
when they Know and Observe the Appointed Time of their Coming, " published in
1703. It is written "By a Person of Learning and Piety, whose "probable solution"
stated migratory birds flew to the moon and there spent the winter.
Some people who easily accepted the migratory travels of larger birds were
unable to understand how smaller species, some of them notoriously poor flyers,
could make similar journeys. They accordingly conceived the idea that larger
species (e.g., storks and cranes) carried their smaller companions as living freight.
8/21/2019 Migracion Aves
55/255
33
In some southern European countries, it is still believed these broad-
pinioned birds serve as aerial transports for hosts of small birds that congregate
upon the Mediterranean shore awaiting the opportunity for passage to winter homes
in Africa. Similar beliefs, such as hummingbirds riding on the backs of geese, have
been found among some tribes of Native Americans in the Western Hemisphere.
Such fantasies, however, are not without some empirical basis, such as the
observation of an Eastern Kingbird harassing a Great Horned Owl that actually
perched on the shoulder of the owl's outstretched wing as the owl glided toward
wooded cover.
Today we realize that birds do not migrate by "hitching" rides with other
birds and that the scope of the migration phenomenon is worldwide, not simply
limited to the Northern Hemisphere or the world's land masses. The migration
heritage is developed just as extensively in Old World warblers migrating to and
from Europe and Africa as in our wood warblers traveling from Canada and the
United States to South America and back. Although South Temperate Zone species
migrate northward to the tropics during the austral winter, no land species nesting in
the South Temperate Zone migrates into the North Temperate Zone. Some seabirds
like the Sooty Shearwater and Wilson's Storm petrel, however, migrate to North
Temperate seas after nesting on shores south of the equator (Northern Prairie
Wildlife Research Center).
2.5.1 The Concept of bird migration
The changing picture of bird populations throughout the year intrigues those
who are observant and who wish to know the source and destination of these birds.
While many species of fish, mammals, and even insects undertake amazing
migratory journeys, birds as a group are the most mobile creatures on Earth. Even
8/21/2019 Migracion Aves
56/255
34
humans with their many vehicles of locomotion do not equal some birds in
mobility. No human population moves each year as far as from the Arctic to the
Antarctic with subsequent return, yet the Arctic Terns do.
Birds are adapted in their body structure and physiology to life in the air.
Their feathered wings and tails, bones, lungs and air sacs, and their metabolic
abilities all contribute to this amazing faculty. These adaptations make it possible
for birds to seek out environments most favorable to their needs at different times of
the year. This result in the marvelous phenomenon we know as migration the
regular, recurrent, seasonal movement of populations from one geographic location
to another and back again.
Throughout human experience, migratory birds have been important as a
source of food after a lean winter and as the harbinger of a change in seasons. The
arrival of certain species has been heralded with appropriate ceremonies in many
lands. Among the Eskimos and other tribes this phenomenon is the accepted sign of
the imminence of spring, of warmer weather, and a reprieve from winter food
shortages. The European fur traders in Alaska and Canada offered rewards to the
Native American who saw the first flight of geese in the spring and all joined in
jubilant welcome to the newcomers (Shaw Creek Supply).
2.5.2 Techniques for studying migration
The following are the techniques normally used for studying bird migration.
8/21/2019 Migracion Aves
57/255
35
2.5.2.1 Direct Observation
The oldest, simplest, and most frequently used method of studying
migration is by direct observation. Size, color, song, and flight of different species
all aid the amateur as well as the professional in determining when birds are
migrating. Studies by Wells W. Cooke and his collaborators from 1888 to 1915 and
continued by his successors in the U.S. Bureau of Biological Survey (later U.S.
Fish and Wildlife Service) were of particular importance in the earlier years of these
investigations in North America. Tediously compiling and comparing literally
thousands of observations of species in a given locality at a particular time of the
year sorted some of the largest and most interesting routes and patterns out.
Most recently, the National Audubon Society and Audubon and
ornithological societies have published information in their bulletins and
newsletters on direct observation of migration. In the aggregate, direct observation
has contributed much to our knowledge of migration, but this method is limited byits being largely restricted to daytime, ground-based data on birds either before or
after a period of actual migratory flight.
2.5.2.2 Aural
Another nocturnal observation method, which has potential for species
identification during the study of migration, is the use of a parabolic reflector with
attached microphone to amplify call (chip) notes. This device, when equipped with
a tape recorder, can record night migrants up to 11, 000 feet on nights with or
without a full moon. A primary disadvantage is that one cannot tell the direction a
bird is traveling. Furthermore, there may be some difficulties in identifying the
8/21/2019 Migracion Aves
58/255
36
chip notes made by night migrants, since these calls are often different from the
notes heard during the daytime. Unfortunately, the bird may not call when it is
directly over the reflector and consequently it would not be recorded.
2.5.2.3 Preserved Specimens
Reference material consisting of preserved bird skins with data on time and
place of collection exists in many natural history museums. The essentialingredient in studying migration by this method is to have an adequate series of
specimens taken during the breeding season so differences in appearance between
geographically separated breeding populations of the same species can be
discerned. Such properly identified breeding specimens may be used for
comparison with individuals collected during migration to associate them with their
breeding areas. This provides a convenient way of recognizing and referring to
individuals representative of known populations wherever they may be
encountered.
2.5.2.4 Marking
If birds can be captured, marked, and released unharmed, a great deal of
information can be learned about their movements. Many different marking
methods have been developed to identify particular individuals when they are
observed or recaptured at a later date. Since 1920, the marking of birds with
numbered leg bands in North America has been under the direction of the U.S. Fish
and Wildlife Service and more recently the Biological Resources Division of the
U.S. Geological Survey in cooperation with the Canadian Wildlife Service. Every
year professional biologists and volunteers, working under permits, place bands on
8/21/2019 Migracion Aves
59/255
37
thousands of birds, game and nongame, large and small, migratory and
nonmigratory. Each band carries a serial number on the outside and an address
where recovered bands can be sent on the inside. When a banded bird is reported
from a second locality, a definite fact relative to its movements becomes known.
The study of many such cases leads to a more complete knowledge of the details of
migration.
The records of banded birds have also yielded other important information
related to migrations, such as arrival and departure dates, the length of time
different birds pause on their migratory journeys to feed and rest, the relation
between weather conditions and starting times for migration, the rates of travel for
individual birds, and the degree of regularity with which individual birds return to
the summer or winter quarters used in former years. Many banding stations are
operated systematically throughout the year and supply much information
concerning the movements of migratory birds that heretofore could only be
surmised. The most informative banding studies are those that focus on particular
populations of birds. Examples of such planned banding programs are the extensive
marking of specific populations of ducks and geese on their breeding grounds by
the U.S. Fish and Wildlife Service and the Canadian Wildlife Service, as well as
Operation Recovery, the cooperative program of banding small land birds along
the Atlantic Coast. When these banded birds are recovered, information concerning
movements and survival rates of specific populations or the vulnerability to hunting
is gained. Coloured leg bands, neck collars, or streamers can be used to identify
populations or specific individuals, and birds marked with easily observed tagscould be studied without having to kill or recapture individuals, thus making it a
particularly useful technique.
We have learned about the migratory habits of some species through
bandings, but the method does have shortcomings. To study the migration of a
8/21/2019 Migracion Aves
60/255
38
particular species through banding, the banded bird must be encountered again at
some later date. If the species is hunted, such as ducks or geese, the number of
returns per hundred birds banded is considerably greater than if one must rely on a
bird being retrapped or found dead. For example, in Mallards banded throughout
North America the average number of bands returned the first year is about twelve
percent. In most species that are not hunted, less than one percent of the bands are
ever seen again.
In 1935, Lincoln commented that with enough banding some of the winter
ranges and migration routes of more poorly understood species would become
better known. A case in point is the Chimney Swift, a common bird in the eastern
United States. This species winters in South America. Over 500, 000 Chimney
Swifts have been banded, but only 21 have been recovered outside the United States
(13 from Peru, 1 from Haiti, and the rest from Mexico). The conclusion is simply
this: whereas banding is very useful for securing certain information, the volume of
birds that need to be banded to obtain a meaningful number of recoveries for
determining migratory pathways or breeding or wintering areas may be prohibitive.
One problem in interpretation of many banding results is the fact that recoveries
may often reflect the distribution of people rather than the distribution of birds.
2.5.2.5 Radio Tracking
Radio tracking, or telemetry, is accomplished by attaching a small radio
transmitter that gives off periodic signals or beeps from a migrating bird. With a
radio receiving set mounted on a vehicle or airplane, it is possible to follow these
radio signals and trace the progress of the migrating bird. Richard Graber reported
one of the most dramatic examples of this technique in 1965. He captured a Gray-
8/21/2019 Migracion Aves
61/255
39
cheeked Thrush on the University of Illinois campus and attached a 2.5-gram
transmitter (a penny weighs 3 grams). The bird was followed successfully for over
eight hours on a course straight north from Urbana, across Chicago, and up Lake
Michigan on a continuous flight of nearly 400 miles at an average speed of 50 mph
(there was a 27 mph tail wind aiding the bird). It is interesting to note that while the
little thrush flew up the middle of Lake Michigan, the pursuing aircraft skirted the
edge of the lake and terminated tracking at the northern end after running low on
fuel while the bird continued to fly on. The limitations of radio telemetry, of
course, are the size of the transmitter that can be placed on birds without interfering
with flight and the ability of the receiving vehicle to keep close enough to the flyingbird to detect the signals. Despite this difficulty, there has been considerable
development in the technology, and encouraging results to date give promise for the
future, particularly when birds can be tracked by orbiting satellites. Yet this
technique should be used cautiously, since several studies have demonstrated that
transmitter-equipped birds have significantly lower survival.
2.5.2.6 Radar Observation
Radar was developed to identify and track aircraft electronically and was an
innovation that was critical to Englands success in the Battle of Britain during the
early years of the Second World War. Early radar observers noted, however, that
they received moving returns that could not be associated with aircraft. These radar
echoes, whimsically termed angels by observers in England, were soon
discovered to be birds. Students of migration seized upon that bird flight could be
monitored by radar after the end of the war as an opportunity to obtain information
on the movements of birds during both day and night and over extensive geographic
areas.
8/21/2019 Migracion Aves
62/255
40
Three types of radar have been used for studying birds: 1) general
surveillance radar, similar to ones located at airports, that scans a large area and
indicates the general time and direction of broad movements of birds; 2) tracking
radar that records the path of an airplane (or bird) across the sky by "locking on" to
a designated target and continuously following only that object; and 3) Doppler
radar similar to those operated by law enforcement agencies for measuring the
speed of a passing automobile or by meteorologists for detecting tornadic winds.
The data collected by radar can be electronically stored in the absence of a human
observer and can be correlated with weather data sets.
The use of radar in migration studies has been invaluable in determining
direction and speed of mass bird movements, dates and times of departure, height of
travel, and general volume, especially at night. One interesting fact to come out of
current radar work is the discovery of relatively large movements of warblers and
other small land birds migrating over oceans rather than along coastlines and in
directions about which ground-based observers were completely unaware (Northern
Prairie Wildlife Research Center).
