Bald Eagles can be seen all over North America. Did you know that the Bald Eagle is a national symbol of the United States? The largest number of Bald Eagles live in Alaska and British Columbia. Eagles are the second largest bird in North America. If you see two Bald Eagles together and one is larger than the other, there is a good chance that the larger one is a female. Female Bald Eagles are 25% larger than the males. The adults have the same colour plumage: brown feathers cover the body and white feathers cover the tail and head. Bald Eagles have a yellow iris, yellow talons as well as a yellow hooked bill and cere. The cere is the upper part of the beak where nostrils are found. Adult plumage colours are reached when the bird becomes sexually mature at 4 to 5 years of age. Juvenile Bald Eagles are brown with some white feathering, grey eyes and light yellow feet.
