Bald EagleHaliaeetus leucocephalus 
HabitatThe bald eagle historically ranged throughout north america except extreme northern alaska and canada, and central and southern mexico.
DescriptionThe bald eagle is a large raptor. The characteristic adult plumage consists of a white head and tail with a dark brown body. Juveniles do not develop the majestic white head and tail until the fifth or sixth year. Fish are the primary food source but they will also take a variety of birds, mammals, and turtles (both live and as carrion) when fish are not readily available. Adults average about 1 m. from head to tail, weigh approximately 5 to 6 kilos and have a wingspread that can reach 2 m. Generally, female bald eagles are somewhat larger than the males.
Threats ToThe use of ddt after ww2 to control mosquitos had a drastic effect on the bald eagle as a result of foraging on contaminated food which affected their egg shells, which became thin and easily broken in the nest. |
