Bald Eagle

Caption: I photographed this four year old male juvenile bald eagle at the "Raptors In Flight" show at Winnipeg's Assiniboine Park Zoo. The Bald Eagle is a large bird, with a body length of 28–38 inches, a wingspan of 66–88 inches, and a mass of 6.6–14 lbs.; females are about 25 percent larger than males. The adult Bald Eagle has a brown body with a white head and tail, and bright yellow irises, taloned feet, and a hooked beak; juveniles are completely brown except for the yellow feet. Males and females are identical in plumage coloration. Its diet consists mainly of fish, but it is an opportunistic feeder. It hunts fish by swooping down and snatching the fish out of the water with its talons. It is sexually mature at four years or five years of age. In the wild, Bald Eagles can live up to thirty years, and often survive longer in captivity. The Bald Eagle is a powerful flier, and soars on thermal convection currents. It reaches speeds of 35–44 miles per hour when gliding and flapping, and about 30 miles per hour while carrying fish. It is partially migratory, depending on location. If its territory has access to open water, it remains there year-round, but if the body of water freezes during the winter, making it impossible to obtain food, it migrates to the south or to the coast. The Bald Eagle selects migration routes which take advantage of thermals, updrafts, and food resources. During migration, it may ascend in a thermal and then glide down, or may take ascend in updrafts created by the wind against a cliff or other terrain. Migration generally takes place during the daytime, when thermals are produced by the sun. Bald Eagles normally squeak and have a shrill cry, punctuated by grunts. They do not make the scream that is found in films; this is usually the call of a Red-tailed Hawk, dubbed into films for dramatic effect. The Bald Eagle's diet is opportunistic and varied, but most feed mainly on fish. In the Pacific Northwest, spawning trout and salmon provide most of the Bald Eagles' diet. Locally, eagles may rely largely on carrion, especially in winter, and they will scavenge carcasses up to the size of whales, though it seems that carcasses of ungulates and large fish are preferred. They also may sometimes feed on subsistence scavenged or stolen from campsites and picnics, as well as garbage dumps. Mammalian prey includes rabbits, hares, raccoons, muskrats, beavers, sea otters, and deer fawns. Preferred avian prey includes grebes, alcids, ducks, gulls, coots, egrets and geese. Most live prey are quite a bit smaller than the eagle, but predatory attacks on large birds such as the Great Blue Heron and even swans have been recorded. Reptiles, amphibians and crustaceans (especially crabs) are preyed on when available.
