How do golden eagles differ from bald eagles?

Golden eagles (Aquila chrysaetos) and bald eagles (Haliaeetus leucocephalus) are both large birds of prey but have distinct differences. Golden eagles are dark brown with golden nape feathers, dark eyes, and fully feathered legs. They are found across the Northern Hemisphere. Bald eagles, on the other hand, are characterized by their white heads and tails, which contrast with their dark brown bodies and wings. This white plumage develops as they mature. Bald eagles are unique to North America and are the national bird of the United States. While both species mate for life and build large nests, female bald eagles are larger than males, with wingspans reaching up to 2.5 meters (8 feet).1234
