Pere David's Deer Pere David's Deer

( Elaphurus davidianus)( Elaphurus davidianus)

. Known in Chinese as Milu, their English name is derived from the

French missionary Father Armand David .

They were reintroduced into China in the late 1980s from captive animals bred in Europe; these reintroduced animals have been managed since then and are not

considered as wild. The captive population in China has increased in recent years, and the possibility remains that free-ranging populations can be established sometime in

the near future

The last wild population is thought to have been eaten by troops during

the Boxer Revolution at the turn of the 19th century.

The Slender-billed Vulture ( Gyps tenuirostris )The Slender-billed Vulture ( Gyps tenuirostris )

Was once a common species, but in Southeast Asia it declined through the latter half of the 19th century and the first half of the 20th century; it is now listed as Critically Endangered.

A recent survey recorded small numbers in Myanmar; very sharp declines have been noted in the last few years in India and Nepal; it is now thought to be extinct in Thailand and Malaysia, and the only recent Southeast Asian records are from Cambodia and southern Laos.

By mid-2000, Gyps vultures were being found dead and dying in Nepal and India, and major declines and local extirpations were reported. There is strong evidence that Gyps vultures are fatally susceptible to veterinary painkillers containing Diclofenac. East of India, the near-total disappearance of the species pre-dated the present crisis, and probably results from the rarity there of large wild mammals and human consumption of deceased livestock.
