How big are bald eagles?
A. Sizes and weights vary greatly. Southern birds are smaller and lighter than northern birds; an Alaskan male can weigh about the same as a southern female. Average lengths range from 71 to 96 centimetres (2.3 to 3.1 feet). Average weights range from just under 3 kilograms to 6.3 kilograms (6.6 pounds to 14 pounds) although weights as high as 7.7 kilograms (17 pounds) have been recorded for Alaskan females. Averaged across their entire range, male weights range from 3.6 to 4.1 kilograms (8 to 9 pounds); female weights range from 4.5 to 6.4 kilograms (10 to 14 pounds). Average wingspans range from 168 to 244 centimetres (5.5 to 8 feet).
