Raven (bird)

right|300px|Northern Raven at Shadow Moses Island Ravens are one of several larger-bodied members of the genus Corvus, identifiable by their black plumage and large beaks. A notable breed is the Northern Raven. They frequently fed on garbage, which ensured they survived even in places like Alaska. In addition, they also had a long longevity, reaching upwards of 75 years for Northern Ravens, and was the reason behind the wives-tale of Ravens having three times the lifespan of humans, who likewise have three times the lifespan of crows.

Several ravens were found at the United States Naval Prison Facility in Cuba between December 1974 and March 1975.

During the Shadow Moses Incident in 2005, the population of Northern Ravens boomed after FOXHOUND arrived and took over the facility on Shadow Moses Island. Several ravens were found in the freight elevators of the underground facility area, and several also aided Vulcan Raven in fighting Solid Snake, with Raven in particular getting enraged if Snake killed several of the birds. After Vulcan Raven was defeated and mortally wounded, his ravens ate him alive, leaving literally nothing behind afterwards.

Northern Ravens were also found during the return trip to Shadow Moses in 2014.
