The Isabela oriole (Oriolus isabellae) is a species of the oriole family endemic to Luzon in the Philippines. The bird was presumed to be extinct for many years until its rediscovery in December 1993 near Diffun, Quirino,[2] and in Mansarong, Baggao, Cagayan in September 1994.[3] Additional sightings were made in 2004 near San Mariano, Isabela.[4]

Taxonomy and systematics

The Isabela oriole is most closely related to the white-lored oriole. Both species are closely related to the paraphyletic Philippine oriole.[5] The Isabela oriole is sometimes considered to form a superspecies with the dark-throated oriole and the Philippine oriole.[6] Alternate names for the Isabela oriole include the green-lored oriole and olive-lored oriole.

Distribution and habitat

The Isabela oriole is found in the mountains of northern Luzon.[7] It has not been recorded in Bataan province since 1947.[8]

Status

The Isabela oriole has a known population of about fifty individuals and is assessed as Critically Endangered based on its extremely small and fragmented population.[8]
