Subadult, note white in tail and dark neck.Adult Golden Eagles range widely in size across their range.
The largest subspecies are among the largest eagles of the genus Aquila. Length may vary from 66 to 100 cm (26-40 in),
wingspan can range from 150 to 240 cm (59-95 in), and weight is from 2.5 to 7 kg (5.5-15.4 lb).
As with many Falconiformes, females are considerably larger than males, in the case of the Golden Eagle they weigh
one-fourth to one-third again as much as male birds.

The plumage colours range from black-brown to dark brown, with a striking golden-buff crown and nape, which give the bird
its name. The upper wings also have an irregular lighter area. Immature birds resemble adults, but have a duller more mottled appearance. Also they have a white-banded tail and a white patch at the carpal joint, that gradually disappear with every moult
until full adult plumage is reached in the fifth year.
