The golden eagle is a very large, dark brown raptor with broad wings, ranging from 66 to 102 cm (26 to 40 in) in length and from 1.8 to 2.34 m (5 ft 11 in to 7 ft 8 in) in wingspan. This species' wingspan is the fifth largest amongst extant eagle species. In the largest race (A. c. daphanea) males and females weigh typically 4.05 kg (8.9 lb) and 6.35 kg (14.0 lb). In the smallest subspecies, A. c. japonica, males weigh 2.5 kg (5.5 lb) and females 3.25 kg (7.2 lb).
As with many raptors, females are larger than males. The bald eagle is Alaskaâs largest resident bird of prey with a wing span of up to 7.5 feet (2.3 m) and weight between 8 to 14 pounds (3.6 â 6.4 kg). Found only in North America, bald eagles are more abundant in Alaska than anywhere else in the United States. The Alaska population is estimated at 30,000 birds.
