Oriental White-backed Vultures |
Oriental
White-backed Vulture, Gyps bengalenis
Other common names: Indian White-backed/White-rumped
Vulture
Taxonomy: Vultur bengalensis Gmelin, 1788,
Bengal. Monotypic. Forms a superspecies with Gyps
africanus, with which it is sometimes considered
conspecific; these two are sometimes separated off into
the genus Pseudogyps.
Distribution and abundance: As recently as the early
1990s considered among the most abundant birds of prey in
India and Pakistan. Now very rare throughout its range,
from Pakistan through India and Nepal to south central
China (Yunnan), Indochina, and north Malay Peninsula.
Description: 76-93 cm; 3500-6000 g; wingspan 205-220
cm. Adult blackish, medium-sized vulture with white lower
back; underwing coverts conspicuously all white; bill and
cere dark. Juvenile dark brown, with streaked underparts.
Habitat: Inhabits open country near villages, towns,
and cities, as well as parks and sanctuaries, in lowlands
and Himalayan foothills up to 1,500 m. Often closely
associated with humans, large numbers congregated in and
around towns, especially by rubbish dumps and
slaughterhouses. Often gathered to roost in large numbers
in trees for long periods.
Food and feeding: Exclusively carrion feeders,
especially the remains of cattle. Regularly feeds in
company of other vultures, especially Gyps indicus,
and also other scavengers, e.g., jackals, dogs, and
corvids. Carrion located by means of keen eyesight and
following other avian scavengers. As in other vulture
species, birds tend to gorge themselves, then rest for a
long period nearby while food is digested.
Breeding: Season is October through April/May. Forms
small (<10) to large (>1000 pairs) colonies in suitable
tree groves. A large stick nest is built by a pair, 5-30 m
up large trees, often in a village, town, or even city,
and often next to a road, stream, or canal. Display
flights consist of close mutual soaring of pair. Lays a
single egg; incubation at least 45 days by both sexes;
nestling period about three months; post-fledgling
dependence period is unknown.
Movements: Mainly sedentary when breeding, but foraging
movements may exceed 100 km per day. No migratory
movements are known but young birds or unpaired adults
have the flight capacity to wander over a huge area.
Status and conservation: Globally critically endangered
due to catastrophic decline since early 1990s. Species
survival depends on removing the pharmaceutical drug
diclofenac from vulture food sources, and species recovery
efforts. Listed in CITES Appendix II, CMS Appendix II. Not
known to be traded so no need to raise CITES level.

Long-billed Vultures |
Long-billed Vulture,
Gyps indicus
Other common names: Indian Vulture, Cliff Vulture
Taxonomy: Vultur indicus Scopoli, 1786, India.
May form superspecies with G. himalayensis, G. fulvus,
G. coprotheres, and G. rueppellii. Sub-species
tenuirostris now considered a separate species.
Distribution and abundance: As recently as the early
1990s considered among the most abundant birds of prey in
India. Now very rare throughout its range, from southeast
Pakistan and India south of the Ganges River except the
extreme south.
Description: 80-100 cm; 5500-6300 g; wingspan 205-229
cm. Medium-sized vulture with pale body and wing coverts;
blackish neck with whitish down; bill mostly pale yellow.
Juvenile darker.
Habitat: Inhabits open country near villages, towns,
and cities, as well as parks and sanctuaries, in lowlands.
Often closely associated with humans, large numbers
congregated in and around towns, especially by rubbish
dumps and slaughterhouses. Occurs on lowland plains,
nesting on cliffs.
Food and feeding: Exclusively carrion feeders,
especially the remains of cattle. Regularly feeds in
company of other vultures, especially the once more
numerous Gyps bengalensis, and also other
scavengers, e.g., jackals, dogs, and corvids. Carrion
located by means of keen eyesight and following other
avian scavengers. As in other vulture species, birds tend
to gorge themselves, then rest for a long period nearby
while food is digested.
Breeding: Season is October through April/May. Forms
small (<10) to large (>200 pairs) colonies on suitable
cliffs. Nest is a loose platform of sticks lined with
grass and leaves. Display flights consist of close mutual
soaring of pair. Lays a single egg; incubation at least 45
days by both sexes; nestling period about three months;
post-fledgling dependence period is unknown.
Movements: Mainly sedentary when breeding, but foraging
movements may exceed 100 km per day. No migratory
movements are known but young birds or unpaired adults
have the flight capacity to wander over a huge area.
Status and conservation: Globally critically endangered
due to catastrophic decline since early 1990s. Species
survival depends on removing the pharmaceutical drug
diclofenac from vulture food sources, and species recovery
efforts. Listed in CITES Appendix II, CMS Appendix II. Not
known to be traded so no need to raise CITES level.
Slender-billed Vulture,
Gyps tenuirostris
Taxonomy: Gyps indicus tenuirostris G.R. Gray,
1844. Now considered a separate species Gyps
tenuirostris (Rasmussen and Parry, 2000).
Distribution and abundance: Gangetic Plain from at
least western Uttar Pradesh along the lower Himalayas
through Nepal to Assam, south to Calcutta and Bangladesh.
Formerly found at least sporadically as far east and south
as Vietnam and Malaysia, but has almost disappeared from
southeast Asia. Small numbers of birds recently seen in
Cambodia. Status unknown but apparently now very rare
(only one colony known of >10 pairs in Nepal).
Description: Similar in size to the Long-billed
Vulture, the Slender-billed Vulture looks markedly
different from other Gyps, with a slender neck,
thin elongate bill and front of face, angular crown, and
generally more slender body appearance, with darker
coloration.
Habitat: Inhabits open country near villages, towns,
and cities, as well as parks and sanctuaries, in lowlands
and foothills of the Himalayas. Nests in loose colonies
(lower density than either Gyps bengalensis or
indicus) in trees.
Food and feeding: Exclusively carrion feeders,
especially the remains of cattle. Regularly feeds in
company of other vultures, especially the once more
numerous Gyps bengalensis, and also other
scavengers, e.g., jackals, dogs, and corvids. Carrion
located by means of keen eyesight and following other
avian scavengers. As in other vulture species, birds tend
to gorge themselves, then rest for a long period nearby
while food is digested.
Breeding: Season is October/November through
March/April. Forms small (<10) loose (lower density)
colonies in suitable trees. Builds a compact nest 7-15 m
up large leafy trees. Display flights not described but
probably like other Gyps consisting of close mutual
soaring of pair. Lays a single egg; adults share nesting
duties; chick has yellowish brown down. No further
information available.
Movements: Mainly sedentary when breeding. No migratory
movements are known but young birds or unpaired adults
have the flight capacity to wander over a huge area.
Status and conservation: Globally critically endangered
due to catastrophic decline since early 1990s. Species
survival depends on removing the pharmaceutical drug
diclofenac from vulture food sources, and species recovery
efforts. Listed as Gyps indicus in CITES Appendix
II and CMS Appendix II. Not known to be traded so no need
to raise CITES level.
