Northern bald eagle

The adult has a distinctive snow-white head and tail. The body is brownish-black. The large bill, eyes, and feet are bright yellow. In immature birds the tail, head, and body are dark brown, less black than adults, and show some white on the underside of the wings. In some, the plumage is irregularly but extensively blotched with cream or white, with the bill brownish, eyes pale yellow-gray, and feet lemon yellow. They take four to five years to acquire adult colouration. Females are larger than males weighing approximately 5.8 kg on average, whereas males weigh 4.1 kg. Wingspan can reach up to 2.44 m.
