[Length 31 (Male) to 37 (Female) in. Wingspan 70 (M) to 90 (F) in.]

National symbol of the United States, the adult Bald Eagle, with its dark brown body and all white head and tail, is unmistakable when seen in the field. The Bald Eagle gets its name from the white feathers which cover the head of the adult, making it appear "bald" when seen from a distance. Young birds are dark overall with whitish wing linings and a variable amount of white in the tail. They require 4 to 5 years to attain full adult plumage. The Bald Eagle breeds in Alaska (more than 50% of the total population), northern and eastern Canada, the Northern US states, and Florida. It is always found along lakes, rivers, and coastal areas, often in large concentrations in winter where there is open water. This Bald Eagle was photographed at the West Entrance Road near Madison, Yellowstone National Park, Wyoming, USA. Photo taken with a AF-S VR Nikkor 300mm f/2.8G IF-ED lens + Nikkor TC17E II 1.7x Teleconverter on a Nikon D7100 camera. (Date: June 14, 2016)
