NatureServe Explorer is a product of NatureServe in collaboration with the Natural Heritage Network. The Mariana crow (Corvus kubaryi) (Chamorro name: aga) is a species of the crow family from the South 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 believed to be very few remaining birds, the population having been much reduced since the introduction of the brown tree snake. On Rota the population has also been dwindling, the main threats here being the reduction of suitable habitat because of development and predation. Some conservation efforts have been undertaken, and some birds have been relocated from Rota to the new Guam National Wildlife Refuge. The International Union for Conservation of Nature has rated the bird as being “critically endangered”.
