“White-backed and slender-billed vultures are still at risk, the RSPB study shows.”
“The RSPB said the research, conducted to examine the effectiveness of the banning of the drug in 2006 in India followed by further measures in August 2008, showed that oriental white-backed, long-billed and slender-billed vultures were still at risk.”
“It is also essential winter habitat for up to 500,000 overwintering ducks and waterbirds such as teal Anas crecca (160,000), wigeon Anas Penelope (100,000), greylag goose Anser anser (100,000), most of Spain's herons, white stork Ciconia ciconia, stone-curlew Burhinus oedicnemus and slender-billed gull Larus genei.”
“The slender-billed vulture is one of several vulture species in Asia that have been driven to the brink of extinction across its entire range due to Diclofenac, an anti-inflammatory drug used for cattle that is highly toxic to vultures.”
“Diclofenac has lead to global population declines as high as 99 percent in slender-billed and other vulture species.”
“Found in heavily forested country just east of the Mekong River in Cambodia's Stung Treng Province, the colony also represents one of the only known slender-billed vulture nesting areas in the world, and therefore one of the last chances for recovery for the species, now listed as 'Critically Endangered' by the World Conservation Union (IUCN).”
“Working in the remote forests of Cambodia, conservationists from the Wildlife Conservation Society (WCS) have just discovered Southeast Asia's only known breeding colony of slender-billed vultures, one of the world's most threatened bird species.”
“It is possible that the globally threatened slender-billed curlew (Numenius tenuirostris, CR) uses some of the ephemeral wetlands in this ecoregion, as this species is also found during the winter months in a few North African coastal wetlands.”
“Populations of the long-billed vultures have dropped to 45,000 while only an estimated 1,000 of the slender-billed species remain.”
“The study confirms that the population of oriental white-backed vultures has plunged 99.9 per cent since 1992 while the numbers of two species, the long-billed and slender-billed vultures, together have fallen by nearly 97 per cent.”
