Isabela oriole

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]

gollark: Also, you might be able to get the carbon out as diamonds using whatever magic molecular reorganization thing you're using to do this, in which case it doesn't need to be buried and we can just use ridiculous volumes of diamond as a structural material.
gollark: *Can* you efficiently just convert carbon dioxide/water back into oxygen/carbon? I mean, the whole reason we do it the other way round is the fact that a lot of energy is released.
gollark: Or just keep them lying around, like in forests, but there are capacity limits.
gollark: I mean, plants turn carbon dioxide into... plant bits... which means you have to grow plants and then stockpile those plant bits somewhere without burning them.
gollark: Funnily enough, photovoltaic panels are actually more efficient at sunlight→energy conversion than plants.
