Genus (Animalia): Haliaeetus

A sea eagle (also called erne or ern, mostly in reference to the white-tailed eagle) is any of the birds of prey in the genus Haliaeetus in the bird of prey family Accipitridae.

Description

Sea eagles vary in size, from Sanford's sea eagle, averaging 2.0–2.7 kg (4 lb 7 oz–5 lb 15 oz), to the huge Steller's sea eagle, weighing up to 9 kg (20 lb). At up to 6.9 kg (15 lb 3 oz), the white-tailed eagle is the largest eagle in Europe. Bald eagles can weigh up to 6.3 kg (13 lb 14 oz), making them the largest eagle native to North America. There are exceptional records of even heavier individuals in both the white-tailed and bald eagles, although not surpassing the largest Steller's sea eagles. The white-bellied sea eagle can weigh up to 4.5 kg (9 lb 15 oz). They are generally overall brown (from rich brown to dull grey-brown), often with white to the head, tail or underparts. Some of the species have an all-yellow beak as adults, which is unusual among eagles.

Their diets consist mainly of fish, aquatic birds and small mammals. Nests are typically very large and positioned in a tree, but sometimes on a cliff.
