Steller's Sea-eagle is the biggest bird in the genus Haliaeetus and is one of the largest raptors overall. Females typically weigh from 6.8 to 9 kilograms (15 to 20 lbs), while males are rather lighter with a weight range from 4.9 to 6 kilograms (11 to 13 lbs). At its average weight, the Steller's outweighs both the average Harpy and the average Philippine Eagles by over 0.5 kilograms (1.1 lb). An unverified record exists of a huge female, who apparently gorged on salmon, having weighed 12.7 kilograms (28 lbs). The Steller's Sea Eagle's length can range from 85 to 105 cm (33 to 41 in). The wingspan is from 1.95 to 2.5 m (6.4 to 8.2 ft) and each wing chord is 57–62 cm (22–24 in).
