This stock photo includes numerous bald eagles both adults and juveniles, Haliaeetus leucocephalus, perched in a tree during winter near Beaver Cove, Northern Vancouver Island, Vancouver Island, British Columbia, Canada. The bald eagle is the only eagle unique to North America. At one time, the word "bald" meant "white," not hairless. Bald eagles are found throughout most of North America, from Alaska and Canada to northern Mexico. About half of the world's 70,000 bald eagles live in Alaska. Combined with British Columbia's population of about 20,000, the northwest coast of North America is by far their greatest stronghold for bald eagles. They flourish here in part because of the salmon. Eagles are a member of the Accipitridae family; which also includes hawks, kites, and old-world vultures.
