The Western Tragopan, a highly endangered and globally threatened pheasant will not be bred in the Sarahan Breeding Centre this year. This is to allow the birds to recover from an e-coli infection last year that left them very weak. There are 19 birds in captivity. Last year they had bred 17 fertilized eggs of which only one hatched. The chick died soon after. Three adult birds had also died and post mortem findings narrowed the cause to e-coli infection. The Sarahan Aviary was setup in 1992 to augment the depleting population of the Western Tragopan in the wild. The Western Tragopan has been hunted heavily for its plumage.
