Encyclopedic overview
The Mariana crow (Corvus kubaryi) (Chamorro: åga) is a species of the crow family from the tropical Western Pacific. It is a glossy black bird about 15 inches (38 cm) long and known only from the islands of Guam and Rota.
It is a rare bird which has steadily declined in numbers since the 1960s. On Guam there are no remaining native Mariana crows, the population having been wiped out by the introduction of the brown tree snake. On Rota the population has declined to fewer than 200 individuals, the main threats here being the reduction of suitable habitat because of development and predation. Despite translocations from Rota to the Guam National Wildlife Refuge in the late 1990s and early 2000s, by 2011 the Mariana Crow was extirpated from Guam. Current conservation efforts on Rota include habitat protection, and a captive rear-and-release program. The International Union for Conservation of Nature has rated the bird as being "critically endangered".
