International
Migratory Bird Day, organized by the National Fish and Wildlife
Foundation, will be held on May 14 this year, with the theme
of "Bird Collisions." Organizers will promote awareness
of the large-scale avian mortality at buildings, communication
towers, and other human-made obstacles during migration. This
will include factors that cause avian collisions, including
communication towers, wind turbines, traffic, plate glass, and
power lines. Materials will address the impacts of each, while
offering positive solutions and ways individuals, communities,
and organizations can get involved in minimizing impacts and
conserving birds.
International
Migratory Bird Day is an annual celebration of one of the most
important events in the life of a migratory bird and its journey
between summer and winter homes. IMBD was created to focus public
attention on the need for action to conserve birds and their
habitats through celebrations and education programs
The
objective:
- To
increase public awareness of migratory birds and their conservation
needs
-
To help educators, nature centers, wildlife refuges, classroom
teachers, bird clubs, and bird businesses provide information
about birds and bird conservation.
- To
offer IMBD participants a place where they can find the materials
needed for a festival or education program focusing on birds.
- To
encourage groups of all kinds to host an education event focusing
on birds and bird conservation.
What
has been achieved ?
International
Migratory Bird Day’s principal accomplishments are its
continued growth over the last 10 years and its increased recognition
in the birding community. IMBD is becoming known as an important
source of quality education materials focusing on birds and
provides a venue for diverse groups to share with the public.
IMBD
is also one of the few programs that provides materials in Spanish
to Mexico and countries in Central and South America. The program
works with a number of funders and collaborates with biologists
in Latin America, Canada, and the United States
Bird
migration
One
of the greatest mysteries of bird life is migration or traveling.
Every year, during autumn and early winter, birds travel from
there breeding haunts in the northern regions of Asia, Europe
and America to the southern, warmer lands. They make the return
journey again during spring and early summer
Why
birds migrate?
Food,
water, protective cover, and a sheltered place to nest and breed
are basic to a bird's survival. But the changing seasons can
transform a comfortable environment into an unlivable one --
the food and water supply can dwindle or disappear, plant cover
can vanish, and competition with other animals can increase.
Most
wild animals face the problem of occupying a habitat that is
suitable for only a portion of the year. Fortunately, however,
nature has provided methods for coping with the situation. One
method, known as hibernation, involves entering a dormant state
during the winter season. The other method, known as migration,
involves escaping the area entirely. Because of the powers of
flight, most birds adapt to seasonal changes in the environment
by migrating.
How
they do it ?
Some
birds make the long journey in easy stages, stopping to rest
on the way. Others fly great distances without pausing to rest
and feed. Some fly by day, some both by day and by night, but
most of them speed on their way through darkness after the sun
has set.
Birds
usually travel in flocks. The V-shaped formation of cranes and
geese attracts much attention as the bird's speed across the
sky. Swallows, flycatchers, warblers, shore birds and water-birds
being to gather in flocks- each with its own kind-and, after
a great deal of excited fluttering, twittering and calling,
they rise up into the air and away they go.
Usually
the male birds go first to their breeding grounds in bachelor
parties and the female birds follow them in a few days!
The
movement of birds with the changing seasons was known from the
earliest times, but people had strange ideas as to why the birds
traveled, or where they went. To explain their absence from
a place in a particular season, they said that the birds buried
themselves in the mud and slept there throughout the winter!
Later, detailed studies of migration started. Information was
gained by directly observing the habits of birds, and also by
ringing. Bird movements are also studied by creating artificial
conditions and studying their effects on birds.
Today,
most of the information on migration has come from ringing young
and adult birds. Ringing is done by capturing a bird and putting
on to its leg a light band of metal or plastic. The band bears
a number, date, identification mark, and the address to which
the finder is requested to return the ring. The bird is then
set free. The place where such a bird is shot captured or found
dead gives clue to the direction and locality to which the bird
has migrated.
Classification
of birds
With
regard to periodic seasonal movements, or migration, all birds
can be classified as belonging to one of four groups:
- Permanent
residents, or just "residents," are non-migrating
birds such as House Sparrows who remain in their home area
all year round.
- Summer
residents are migratory birds such as Purple Martins who arrive
in our Northern backyards in the spring, nest during the summer,
and return south to wintering grounds in the fall.
- Winter
residents are migratory birds who have "come south"
for the winter to our backyards. White-throated Sparrows,
who are summer residents in much of Canada, are winter residents
in much of the U.S.
- Transients
are migratory species who nest farther north than our neighborhoods,
but who winter farther south; thus we see them only during
migration, when they are "just passing through.
Advantage
of bird migration
The
advantage of the migration strategy is that, in the long days
of the northern summer, breeding birds have more hours to feed
their young on often abundant food supplies, particularly insects.
As the days shorten in autumn and food supplies become scarce,
the birds can return to warmer regions where the length of the
day varies less and there is an all year round food supply.
Disadvantage
The
downside of migration is the hazards of the journey, especially
when difficult habitats such as deserts and oceans must be crossed,
and weather conditions may be adverse. The risks of predation
are also high. The Eleanora's Falcon which breeds on Mediterranean
islands has a very late breeding season, timed so that autumn
passerine migrants can be hunted to feed its young.
Factors
involved in migration
Whether
a particular species migrates depends on a number of factors.
The climate of the breeding area is important, and few species
can cope with the harsh winters of inland Canada or northern
Eurasia. Thus the Blackbird Turdus merula is migratory in Scandinavia,
but not in the milder climate of southern Europe. The nature
of the staple food is also important. Most specialists insect
eaters are long-distance migrants, and have little choice but
to head south in winter.
Sometimes
the factors are finely balanced. The Whinchat Saxicola rubetra
of Europe and the Siberian Stonechat Saxicola maura of Asia
are a long-distance migrants wintering in the tropics, whereas
their close relative, the European Stonechat Saxicola rubicola
is a resident species in most of its range, and moves only short
distances from the colder north and east.
Another
cause of birds occurring outside their normal ranges is the
"spring overshoot" in which birds returning to their
breeding areas overshoot and end up further north than intended.
A mechanism which can lead to great rarities turning up as vagrants
thousands of kilometres out of range is reverse migration, where
the genetic programming of young birds fails to work properly.
Navigation
How do birds find their way? Simple.
Through
a combination of Sighting (they don't call it a "bird's
eye view" for nothing) features like rivers, coastlines,
and mountain ranges. Monitoring Earth's magnetic field, apparently
with their visual system and with tiny grains of a mineral called
magnetite in their heads Observing the stars
Using the sun for guidance Smell And probably following their
neighbors (many birds migrate in large flocks)
How
do the birds find their way back to home ?
The
ability of birds to return to a familiar place from any distance
is a remarkable feat of nature. For centuries people have taken
advantage of this ability in homing pigeons by using them to
take messages from distant points back to familiar sites. Homing
pigeons are domesticated non-migratory birds with an instinct
to return to their lofts (nesting sites) that is improved with
training and by selective breeding. Training is started at short
distances from the nesting site; over time, this distance is
gradually increased to hundreds of miles from its loft at a
completely unfamiliar location flies in the direction of home
within a minute or two of its release. How does this extraordinary
behavior work?
Understanding
homing behavior is one of the greatest challenges to ornithologists.
Fortunately, because they are able to carefully control the
conditions under which the pigeons are released, researchers
have been able to learn a great deal about how the birds navigate
their way home. Although homing ability has been fostered in
pigeons by careful breeding and selecting of stock, it appears
that training is not always necessary: Many species of wild
birds perform similarly remarkable feats. One such bird is the
migratory Manx Shearwater. Built like tiny albatrosses, these
seabirds spend most of their lives skimming over the ocean surface
far from the sight of land. They come ashore only to nest in
burrows, which they dig in the ground on offshore islands in
order to be safe from predators. The ease of locating and observing
their nests make shearwaters ideal subjects for homing experiments.
Migration trends in India
Some
30 species of birds are involved in this yearly pilgrimage to
and from the Indian subcontinent. They range from the tiny-tot
warblers, half the size of sparrows, to the great dignified
cranes whose calls can fill you with melancholia. Perhaps are
most popular (certainly amongst the sportsmen) are the wildfowl,
the dozen or so species of ducks that rocket across the skies.
Less well-known are the mud-loving waders, those long-legged,
stiletto billed birds that are given short shrift because they
are so similarly clad in splotched greys and browns-and often
very difficult to spot. And almost unnoticed, are the pint-sized
warblers and flycatchers that flit and flicker in gardens and
groves all over the country. Following this largesse of meat
on the wing, are raptors-harriers, falcons and kites, all out
for the killing.
Depending
on the species, the length of the trip may vary between a few
hundred kilometers to a marathon 8000 kilometres (roughly the
distance between India and Siberia from where several of our
migratory species come). While the smaller birds-the warblers,
redstarts and wagtails-may clock a conservative 50 kilometres
per hour, the larger ones, like the ducks and geese can cruise
for hours at double that speed. The average distance flown ranges
between 240 kilometres and 970 kilometres and flying time involved
may be between six and 11 hours. While most birds keep to an
altitude between 500 metres and 1000 metres, some like the Bare-headed
Geese may take a short-cut by overflying the Himalayas. The
smaller species prefer flying by night, the larger ones travel
by day.
On-the-spot
accuracy, which enables the Redstart to find its way to your
lawn without error is brought about by using such navigational
aids as the sun, the stars, landmarks such as mountain ranges
and river valleys and the earth’s gravitational and magnetic
fields. While we know that birds use these aids for direction-seeking,
exactly how they do it still remains baffling. On-the-dot punctuality,
which enables the Redstart to greet you on virtually the same
day every year is governed by hormonal changes which trigger
the travel impulse acting in consonance with the changing length
of day. And the reason behind these monumental journeys, despite
the immense casualties they inflict (due to hunting, had weather
and collision with manmade objects) is simple survival.
Most
of these birds breed in Central Asia, Eastern Europe and Siberia
during summer, which may be a nice enough season to live there.
But these areas turn frigidly inhospitable during winter and
food is virtually impossible to come by. Insect life dies out,
aquatic life is sealed under ice, and animals hibernate undergound.
While here, on the subcontinent, the sun is warm and sublime
and there is plenty to eat everywhere. So the birds fly down
by the million, pouring through the river valleys of the Indus
and Brahampurta on either side of the Himalayas (or simply overflying
the mighty mountain range, and spreading themselves all over
the subcontinent).
The
species, which you are likely to meet, depends largely on the
type or
habitat you frequent. The Redstart on your lawn is likely to
be kept company by the white wagtail, a prosperous looking creature,
in black, white and ash-grey, who will saunter about your property
as though he owns it. Other, slimmer wagtails, usually found
near water, include confusing variants of the yellow and grey,
all of which mercifully however, do wag their tails! In parks
and groves, solemn Redbreasted Flycatchers will twitch and flicker
after insects-little khaki-clad birds with drooping wings and
an orange smudge on their breasts (which only the males have).
Up in the leafy canopy, Lesser Whitethroats will “tch-tch”
disapprovingly at you for no reason at all. If there is pond
or lake nearby, the diminutive Grey-headed Flycatchers, will
call the shots- fiercely driving away any interloper from what
he thinks is his private air-space.
Bird
Sanctuaries in India
Among
the most famous bird sanctuaries in India are, the Keoladeo
Ghana National Park in Bharatpur, the Corbett National Park
and the Sariska Wildlife Sanctuary, part of Project Tiger. These
sanctuaries offer wide variety of bird species. Here one can
watch countless birds in their natural habitat and take pleasure
in their charming habits.
Keoladeo
Ghana National Park is one of India's pioneer wildlife conservation
centers. Considered to be the best sites for bird watching in
the world, the sanctuary annually hosts thousands of visitors
who come to view the spectacular wildlife
Spread
over an area of 30 square km of marshy swamp, kadam forests,
woodland and shallow lakes, the sanctuary offers habitat to
both nesting indigenous birds as well as migratory water birds.
An amazing number of more than 330 species of birds have been
spotted and identified in the sanctuary. The Siberian Crane,
the finest and rarest of migratory birds, are the cynosure this
sanctuary and are regular visitors. Sometimes called 'The Lily
Bird' in India and the 'Snow Wreath' in Russia, the Siberian
Crane is believed to have existed in this world for over one
million years. However it is of great concern that only 125
pairs of these pure white, crimson-billed cranes estimated to
survive worldwide. Profusion of marine vegetation, frogs, fish,
insects and mollusks, as well fine setting for migratory birds
go a long way to make Keoladeo Ghana National Park an ideal
place for pelicans, storks, herons, egrets and kingfishers.
Breeding females stay in peaceful co-existence and it is of
no surprise that one tree can have nests of different birds.
The sanctuary is know to have been the best breeding ground
for more than a thousand species of birds. Migratory birds start
arriving in the month of October. They include a variety of
Geese, Ducks, Raptors, Geese, Warblers and Waders.
Extending
over an area of 800 sq km, the Sariska Wildlife Sanctuary is
located in the forest hills of the Aravalli ranges in the state
of Rajasthan. It provides habitat to more than 200 species of
birds including the Gray Hornbill, Crested Serpent Eagle, Black/Red
Headed Bunting, Wryneck Woodpecker Babbler, White Breasted Kingfisher,
Little Brown Dove, Small Minivet, Golden Oriole, Great Gray
Shrike, Pale Harrier and Tailor Bird. The list goes on. An example
of typical dry deciduous forest, the sanctuary remains lush
and green during the monsoons and dry during the rest of the
seasons.
Other
place is the Pong Dam reservoir is 65 km Pathankot and 115 km
from Dharamsala. Nestled in the sylvan surroundings of the Kangra
valley, the sprawling Pong Dam wetland has emerged as a major
habitat for migratory birds in the country as also an attraction
for bird watchers.
The
most common bird species that have arrived and often visit this
lake every year include ruddy-shell ducks (surkhab), bar-headed
geese, mallards, coots, pochards and pintails besides rare red-necked
grebe and gulls. These species come from as far as China, Siberia,
Central Asia, Pakistan and Ladakh. According to a census, more
than one lakh migratory birds visited the lake last year.
Apart
from being home to the tiger, Corbett National Park is also
noted for the bird watching. Considered to be one of the best
bird watching sites in the world, the park is home to some 600
species of birds. This number exceeds the total number of bird
species found in Europe and is about one fourth of the diversity
found in India. A case in point is that out of the 69 species
of raptors found in India, 49 can be seen in Corbett. Spreading
out on an area of 520 sq km, the Corbett National Park is a
hot destination for bird-watchers. Bird-watchers from across
the world make a beeline to this park during winters when the
bird diversity is at its zenith.
Problems
being faced by bird sanctuaries in India
The
main problem faced by Bharatpur Bird Sanctury is that :
Water
problem . In the past few years farmers have diverted two of
three rivers which once flooded the wetlands, leading to a drop
of more than 50 percent in the number of birds arriving from
northern climates each winter. The consecutive droughts have
dried up the water table in Bharatpur bird Sanctury. The state
of Rajasthan is facing draught problem for the last 2- 3 years.
And this time rains were less. There is a huge water problem.
Every year, around 400 species of birds used to fly in from
various destinations of like China, Europe, Siberia, Russia
and Sri Lanka to the sanctuary. Only 5,700 of the 15-17,000
migratory water birds that regularly visit the park arrived
this year, according to wildlife officials. The problems confronting
Bharatpur are being mirrored across a range of wetlands in India
as urbanisation, growing pollution and demands to feed India's
billion-plus population place massive demands on water supplies.
The shrinking water supply to Bharatpur meant that the migratory
birds where flying to other wetlands in India, where hunters
could stalk them as they lacked the same degree of protection.
Even the alternative homes for the birds are dwindling fast.
Around
38 percent of the wetlands in the country have disappeared over
a 10-year-period between 1991 to 2001, according to the results
of a survey based on satellite imagery conducted by the Space
Application Centre in Ahmedabad (news - web sites).
Municipal
wastes are being dumped into them, wetlands are being converted
into farmland and entire housing colonies are being built on
them. The trend is dangerous because it rewards short-term economic
gain at the cost of ignoring irreparable damage for recharging
groundwater. "The ecosystem service value of wetlands is
20 times that of forests for the same unit area. Wetlands should
not be treated as wastelands. They are the most productive units.
We need a national policy for conserving them.
Problems
faced by birds
Of
the challenges faced by bird populations, the majority are related
to human activities. Some of the most significant threats of
the past century have been overcome due to increased advocacy
for wildlife and the passage of numerous laws protecting birds
and their habitats. However, major threats persist, putting
numerous species at risk and requiring our attention and action.
The fact is that despite the areas set aside for wildlife, some
bird populations are still at risk from habitat loss. Much of
the landscape continues to undergo degradation and conversion
due to human development and disturbance.. In addition, growing
numbers of birds are killed due to collisions with human structures
and equipment, including power lines, communication towers,
wind turbines, glass windows, and automobiles.
Some
species of birds are still threatened by commercial exploitation;
most notably, parrots targeted for the exotic pet bird trade.
Trade in wild-caught parrots, coupled with habitat loss, has
resulted in the parrot family having more globally threatened
species than any other family of birds. The U.S. used to be
the largest consumer of parrots, legally importing 250,000 mostly
wild-caught parrots a year. This changed with the passage of
the U.S. Wild Bird Conservation Act, which controls trade in
parrots listed under the Convention on International Trade in
Endangered Species, and with Mexico’s ban on exporting
parrots. The Act also helped reduce smuggling, but illegally-caught
parrots still flow across the border. The black market and the
legal trade still occurring in many countries are cause for
great concern. Consumers should take care to never buy a wild
caught parrot: for every one that reaches a store, four will
have died along the way. Birds are still victims of pesticide
exposure. An estimated 7 million bird deaths are attributed
to homeowner use of pesticides. These figures do not include
birds that perish after a period of illness, that die after
feeding on poisoned insects, rodents, or other prey, or losses
due to failed reproduction (eggs left unhatched or nestlings
left to starve).
Rapid
Transit: the ins and outs of bird migration
Let's
face it--when it comes to dealing with winter, most birds seem
an awful lot smarter than humans. Instead of griping about the
weather, they simply head for a warmer climate. Let's look at
a few facts on bird migration:
The
arctic tern flies a phenomenal round trip that can be as long
as 20,000 miles per year, from the Arctic to the Antarctic and
back. Other sea birds also make astounding journeys: the long-tailed
jaeger flies 5,000 to 9,000 miles in each direction.
Arctic
terns can migrate as far as 20,000 miles per year.
The
sandhill and whooping cranes are both capable of migrating as
far as 2.500 miles per year, and the barn swallow more than
6,000 miles. For the last word on bird migration, see the Atlas
of Bird Migration.
Why
do about 520 of the 650 bird species that nest in the United
States migrate south to spend the winter ?
Because
they get bored shivering in the dark. And because it's bleak
in the winter. And because there's nothing to eat. And because
their ancestors did it.
Why
do some birds go north for the summer ?
Because
there's more to eat. The 24-hour days near the Arctic Circle
produces a fantastic flowering of life. This brief, but abundant,
source of food attracts many birds (and mammals such as the
caribou) to the Arctic for breeding purposes.
What
influences migration patterns over the long term ?
Changes in climate (particularly ice ages), and shifts in the
positions of islands and continents as a result of tectonic
drift.
How
do they keep going ?
Some
birds store a special, high-energy fat before the trip. Soaring
raptors, for example, may not eat for several weeks as they
migrate. Other species eat along their migration routes.
How high can they fly ?
Higher than Mt. Everest. Bar-headed geese have been recorded
flying across the Himalayas at 29,000 feet. Other species seen
above 20,000 feet include the whooper swan, the bar-tailed godwit,
and the mallard duck.
___________________________________________________________
Some
of the causes behind Vulture decline in central India.
For the last couple of years almost everybody concerned with
nature conservation is worried about the recent disappearance
of vultures. There has been a decline in the population of two
most common species of vultures, the white -backed Gyps bengalensis
and Long-billed Vulture Gyps indicus. What is the cause? Is
it viral attack or something else?
Poisoning and Poaching
Extending the famine time to dangerous levels is one aspect.
What about poisoning and poaching? In Rajasthan, Maharashtra,
Haryana and Punjab when cattle deaths decreased, the persons
engaged in skinning of animals become virtually jobless these
persons have resorted to poisoning stray cattle for their skins
that bring them Rs. 1000-1500 each. The skinned bodies are left
in the field for scavengers. One can imagine death of vultures
due to feeding on such poisoned carcasses. A single case can
finish fifty to hundred vultures instantly or slow poisoning
leading to death.
In areas adjoining forest a cattle kill by a carnivore is invariably
poisoned for skin of the carnivore that brings handsome money.
Even in 10% of poisoning cases the vulture population is at
great risk. A teacher near tamia in Chhindwara district of Madhya
Pradesh told us about death of 150 vultures on a poisoned carcass
of bullock a few years ago. Unfortunately such cases are not
reported and are not published even in local press.
Cattle's Going to Slaughterhouses
There use to be some reluctance in the minds of the older people
to sell an old cow or an old bullock they owned. The new generation
is not that sentimental and does not hesitate to dispose off
unwanted cattle. After having collected the large data about
the cattle going to the slaughterhouses or taking a natural
death in several parts of central India and correlated these
figures with the present vulture population, we can firmly say
that the vultures are dying due to shortage of food now. Incubating
parents are not getting sufficient food nearby nesting site
and hence such sites are reduced.
Loss of Grazing Land
Due to the increase in human population more and more land is
being brought under plough resulting in loss of grazing lands
for the cattle. An average villager finds it difficult to feed
his useful cattle and wants to dispose off the older stock.
In areas where the traditional grazing fields are available,
the situation appears to be normal and vultures can still be
seen.
Modern agriculture practices
In areas where tractor facility is available, the practice to
plough the field by bullock is fast disappearing. In these areas
you can hardly see a bullock cart or see bullocks sloughing
a field. This extreme dependence on tractor in Rajas than, Haryana
and Punjab may some time pose a problem in the event of diesel
scarcity.
Killed For Eyes
Vultures are killed for eyes too. It is believed that one can
locate hidden treasure with the help of "surma" prepared
using the (sharp) eyes of vultures. In a recent shocking incidence
near Sheopur in northwest Madhya Pradesh on 20/2/2001 forty
vultures lost their lives. A cow was poisoned and transported
in a bullock cart to a place far away from the usual skinning
grounds where the vultures perished. A person reported the death
of vultures to forest officials. They found 26 bodies of vultures;
eyes of these vultures were probably removed. Since the case
was four days old the stinking bodies did not permit finer examination.
After finishing the vultures in Rajasthan they (the Surma wallas)
have crossed chambal in search of new vulture areas.
Killed for Skin
Vultures are killed for skin, too. In Sohagpur range of Hoshangabad
dist, the police seized some skins. During investigations it
was found that vulture skins were collected by Pardhis after
trapping them on carcasses, and were sold as rabbit skins. Such
skins are collected at Jabalpur and sent to Bombay where a firm
in Byculla exports such skins.However the same paradhi community
in Amravati district of Maharashtra also found using these skins
,specially on vulture legs, for making the bird traps.

Vulture
Conservation programme in Central India
Study
done by Nature Conservation Society Amravati(NCSA):
NCSA had selected four breeding sites in central India for vulture
conservation project. One near Shivpuri , second near Betul
( both in Madhya Pradesh) ,third in Pench Tiger reserve in Maharashtra
and fourth Paratwada near Melghat Tiger reserve.Inspite of limited
funds available, NCSA kept our study restricted to only two
breeding sites in the breeding season of Oct-2001-to March 2002.
NCSA have simultaneously collected the sighting data from Mandla,
Balaghat,Shivpuri, Jabalpur, Betul districts from Madhya Pradesh
and Amravati, Nagpur,Akola, Bhandara, Chandrapur districts from
Maharashtra.
Objectives of NCSA vulture study Project
1) Breeding site monitoring to see any dead vulture on and around
nest.
2) Monitoring the Vulture population near breeding site.
3) Monitoring feeding areas.
4) Identifying cobblers operating in feeding areas of vulture
and forming rapport with them to help breeding population of
Vultures in the respective area..
5) Discussions with cattle keeping communities in feeding areas
(for paying them not to sell the old cattle to slaughterhouses).
Methodology
1) The local persons in skinning business, cobblers,cattle owners
would be involved in the Project to get their participation.
2) Paying cobblers, cattle owners, skinning persons to ensure
food for vultures and provide non poisoned carcasses to them
in the breeding areas.
3) Paying compensation to old cattle holders to let them die
naturally for making the carcasses of dead cattle available
to breeding population of vultures.
4) Collecting dead vulture samples for testing if some individuals
found dead.
Some of the observations from the Paratwada
(Dist.Amravati) site.
The three nests of Long-billed Vulture are seen at Dharkhora
(Paratwada) site in the present breeding season. On 17 th October
2001 and on 19 th November 2001 our team made visit to the site
and recorded the presence of four Long Billed Vultures but no
nest was recorded on the cliffs. However on 12 th January 2002
the team recorded two nests on the cliff. On 14 th January 2002
the team saw nest building activity of third Long billed Vulture.
No egg was laid by any of these three vultures till our last
visit on 14 th January.
The two vultures (we call them Charlei and Sim) that have completed
their nests, spend their most of the time on the nests. However
other third one (James) is busy in collecting the sticks and
arranging it.
The team interviewed the cobblers from nearby Kohana, Sasoda
and Buradghat village. They are presently jobless as people
from these villages snd their old unproductive cattles to slaughterhouses
as they gets good price like Rs.1000 to Rs.1200 per cattle.
Nobody allows the cattle to die naturally.
Pench Tiger Reserve
Team visited Pench Tiger Reserve and found 5 nests on 3 rd December2001.It
was monitored on 7 th January 2002 and 23 rd February 2002.When
the team inspected the nests on 7 th January 2002 and monitored
all five nests on sadle dam road they found two vultures hatching
eggs whereas one chick was out on another nest. Out of these
nests one was at Kharighat whereas others were in compartment
number 516, 529, 527..Mr.Rangari a keen forest Guard was accompanying
the team who had also reported 20 vultures on the kill.
Last year one Vulture was found dead on the tree in Pench Tiger
reserve and hence the team wanted to check it this year. This
incident of two deaths in Pench has provided researchers a challengeable
job to find out the exact reason.

Vultures Death in Pench :news from Daily Hitawada
In Feb 2001 two White Backed vultures are found dead in Pench
Tiger Reserve.One was hanging dead on the tree whereas another
was found near carcass of Chital.Satpuda Foundation monitoring
Vulture population in Pench Tiger Reseve .
Nature Conservation Society Amravati started working on "Vulture
Conservation Project" in 2001 and small amount was made
available to field activities under this project.Instead of
being a part of controvercial discussion of the cause of "Vulture
decline" NCSA focused on working on all the possible and
said threats by experts.It was decided to monitor the vultures
at selected breeding sites in central India during the breeding
season of these Gyps species.
While monitoring the breeding population of vultures at these
breeding sites NCSA have kept their eyes open to all the possible
causes behind the vulture decline. Most experts suspect that
a viral disease is main cause of death of vultures, however
some does not seem to be adequate evidence and feel that a viral
attack cannot extend all the year round and cannot affect vultures
of the entire subcontinent where the climatic conditions vary
so much.
But these two deaths made ornithologist alert and curious to
check the "disease hypothesis".
Kishor Rithe of Satpuda Foundation have expressed that the saying,
vulture (White-backed and Long-billed) decline is up to 90%
in the Indian sub-continent, is the wild guess. Without knowing
the population of vultures that existed earlier, a percentage
of vulture declines cannot be calculated. No percentage of vulture
declines for the sub-continent is known so far.
He further informed that a disease caused by Birna virus killed
all the vultures in India according to the recent hypothesis
of a group of birdwatchers who beleive in "disease hypothesis".
The same group had suggested that the vulture disease was caused
by Adeno Virus. One year ago the vulture mortality was said
to be due to pesticide bio-accumulation according to the same
group (according to Dr Rahmani's, Director, BNHS reported statement
to Rajya Sabha-Indian Parliament- to a question on the cause
of vulture decline on 12-02-1999). The disease hypothesis has
not been proved yet.
However the local staff of Pench Tiger Reserve is monitoring
the Vultures with NCSA and Satpuda Foundation. RFO Mr.Khandekar
and a forest Guard Mr.Rangari have gathered the data of nests
in Pench Tiger Reserve.
Satpuda Foundation team has made three visits to the Pench to
record observations of breeding population of White Backed Vultures.The
team monitored five nests in Pench.But these deaths have shocked
the team itself as it has proved that Breeding population of
Vultures in Pench is in trouble.
The maximum population of White Backed Vultures seen in Pench
during the survey in December 2002 is 60.
Conclusion
From our four years survey experience we believe that
1) The Vulture decline is primarily connected to the lack of
food and also the fact that wild and domestic animals are often
poisoned, particularly in and around PA's.
2) The domestic cattle are being sold to slaughterhouses in
central India and Cobblers are even found jobless.
3) Incubating parents do not get the food easily around the
nesting sites. These parents do not range far from the nest
in search of food.
4) So finally we have decided to make food available to incubating
parents.
Vulture Conservation in the field
Nature Conservation Society, Amravati (NCSA) has been working
on vulture conservation in central India for the last five years.
Satpuda Foundation has recently joined these efforts and is
helping NCSA in other areas of Maharashtra, besides Madhya Pradesh
and Chattisgarh. We have collected data about the presence of
vultures in central India and also specifically monitored the
breeding sites of Whitebacked and Longbilled Vultures. Our five-year
survey indicates that vulture decline is primarily connected
to lack of food and also to an extent due to the poisoning of
wild and domestic animals, particularly in and around protected
areas. Domestic cattle are being sold to slaughterhouses in
central India. (Even cobblers are found jobless!). Incubating
vultures do not get food easily around their nesting sites,
and they do not range far from the nest in search of food. Nature
Conservation Society, Amravati and Satpuda Foundation jointly
decided to make food available to incubating vultures.
A different problem has emerged, where we now need your help.
Our partner NGO based in a village near Navegaon National Park
in Maharashtra has started feeding carcasses to breeding vultures
in the nearby hills. Because of this effort, the population
of Longbilled as well as Whitebacked Vultures has increased
in and around Navegaon National Park. Here, 80-year-old Madhavrao
Patil, his son and grandson, Bhimsen Patil are putting in tremendous
effort to conserve vultures. Bhimsen Patil convinced a few local
cattle transporters to donate few old cattle (sometimes dead
cattle such as those that die during transportation). Carcasses
are transported to the vulture-breeding site for vultures to
feed on. But dogs are found monopolizing these carcasses and
preventing vultures from feeding. To counter this, we are planning
to erect a reasonably large but low mesh enclosure where we
can keep the carcasses and make them available for safe feeding.
The proposed location is close to the hills where the vultures
breed as well as to a lake on the other side. Vultures need
water immediately after feeding so this location is most suitable.
Veteran ornithologist Mr. P.M. Lad has promised us technical
assistance in this venture.
Abstract
For the last two three years almost everybody concerned with
nature conservation is worried about the recent disappearance
of vultures.There have been a decline in the population of two
most common species of vultures, the white -backed Gyps bengalensis
and Long-billed Vulture Gyps indicus. What is the cause? Is
it viral attack or something else?
Most experts suspect that a viral disease is main cause of death
of vultures, however some does not seem to be adequate evidence
and feel that a viral attack cannot extend all the year round
and cannot affect vultures of the entire subcontinent where
the climatic conditions vary so much.
Nature Conservation Society Amravati started working on "Vulture
Conservation Project" in 2001 and small amount was made
available to field activities under this project. Instead of
being a part of controversial discussion of the cause of "Vulture
decline" NCSA focused on working on all the possible and
said threats by experts. It was decided to monitor the vultures
at selected breeding sites in central India during the breeding
season of these Gyps species.
This report explains about our understanding of the problem

Presence
of humming of birds in forests or gardens is a natural thing
but it is really wonderful that in a site full of chemical plants,
a variety of birds come to roost among the trees in the factories
year after year. These birds build their nests, lay their eggs
and hatch them. After staying for several months they fly away
with their young ones on their long journey, to wherever, only
to return to Atul the next season. Atul Complex provides an
interesting demonstration of this extra ordinary occurrence
because of our commitment to Environmental Protection and Sustainable
Development.
