Isabela Oriole (Oriolus Isabellae)

Isabela Oriole (Oriolus Isabellae)

Recent records of this species suggest that it is likely to have an extremely small and fragmented population that is rapidly declining owing to extensive habitat loss. It has therefore been uplisted to Critically Endangered.
Identification 20 cm. Medium-sized, green and yellow oriole. Olive-green head and upperparts, olive-brown wings, yellow underparts. Large, heavy dark grey bill, dark red iris, dark grey legs. Similar spp. White-lored Oriole O. albilorus has white lores, shorter tail and shorter, more slender dark red bill. Voice Unknown though presumably gives typical oriole phrases.
Range & population Oriolus isabellae is endemic to Luzon in the Philippines. It is known from three localities in Bataan province and five in the north-east of the island. Eleven birds were collected near San Mariano in the Sierra Madre mountains in 11 days in 1961, indicating that it may not have been particularly rare in suitable habitat. However, in the north-east it has been recorded recently at just three localities (in Quirino province and Cagayan province, and in 2003-2004 at Ambabok, Isabela province1), despite an increasing number of fieldworkers attempting to locate it. There have been no observations in Bataan since 1947. This indicates considerable rarity and that its distribution is probably patchy. (Birdlife International)
