The slender-billed vulture ( Gyps
Gyps
tenuirostris) is a recently recognized species of Old World vulture. For some time, it was categorized with its relative, the Indian vulture, under the name of “long-billed vulture”. However, these two species have non-overlapping distribution ranges and can be immediately told apart by trained observers, even at considerable distances. The Indian vulture is found only to the south of the Ganges

and breeds on cliffs while the slender-billed vulture is found along the Sub-Himalayan regions and into Southeast Asia

and nests in trees.

Description[edit] At 80 to 95 cm (31 to 37 in), in length, this mid-sized vulture is about the same size as its sister species, the Indian vulture.[7] This vulture is mostly grey with a pale rump and grey undertail coverts. The thighs have whitish down. The neck is long, bare, skinny and black. The black head is angular and narrow with the dark bill appearing narrow midway. The ear opening is prominent and exposed.[8] Distribution and habitat[edit] The slender-billed vulture is found in India

from the Gangetic plain north, west to Himachal Pradesh, south potentially as far as northern Odisha, and east through Assam.[9] It is also found in north and central Bangladesh, southern Nepal, Burma

Cambodia
may have been partly because diclofenac, which is poisonous to vultures, is not available there. The Royal Society for the Protection of Birds (RSPB) has placed the approximate number of slender-billed vultures living beyond confines at about 1,000 in 2009 and predictions estimate total extinction within the next decade amongst the wild population.[10][11] The slender-billed vulture is a protected species listed on the appendix II list of CITES, because its numbers have declined rapidly. Its decline is largely due to the use of the non-steroidal anti-inflammatory drug (NSAID) diclofenac in working farm animals. Diclofenac
Diclofenac
is poisonous to vultures, causing kidney failure, and is being replaced by meloxicam (another NSAID), which is not toxic to vultures.[12] The retail sale of Diclofenac

is banned by law in India; however, Diclofenac

is still acquired illegally and applied to livestock.[10] Captive-breeding programs in India

are aiming to conserve the species, and it is hoped that vultures can be released back in the wild when the environment is free of diclofenac.[10] Joint efforts between the RSPB and the Zoological Society of London

resulted in the first successful captive breeding in 2009.[10] Two slender-billed vultures hatched and are being independently cared for in Haryana
