	'''RAVENS''' (''Corvus corax''), largest members of the crow family, are skilled fliers known for their aerobatic maneuvers and rolls. They are abundant residents on Santa Rosa and Santa Cruz islands, as well as residents of Anacapa and San Miguel islands, and Santa Barbara Island transients. Historically, ravens were considered a great menace to livestock and vineyards on the islands. Ravens are classified in the phylum Chordata, subphylum Vertebrata, class Aves, order Passiformes, family Corvidae. Ravens are bigger than crows and often occur in pairs or alone, as opposed to crows which commonly occur in flocks. ~~There are~~ no crows on the California Channel Islands.

			'''1941 San Clemente Island:''' “George Willett told of his recent trip to the coastal islands. He spent eight days on San Clemente Island, experiencing bad weather. Birds noted were: 200 Ravens, Rock Wrens, Bewick Wrens and Horned Larks. On the west end of Santa Catalina Island he saw the island form of Allen Hummingbird and two flocks of Black Brant numbering 20 and 30 each. On March 17, on Anacapa Island he found the Brown Pelican with young, and saw Rock Wrens, Bewick Wrens, Golden-crowned Sparrows, Barn Swallows, and White-throated Swifts, but no Cliff Swallows.” [Nokes, Irwin D.
