The bald eagle is predominately blackish-brown in color, with mature adults bearing a white head and tail. Males have a length of 30 to 34 inches and a wingspan of 72 to 85 inches; females are slightly larger. Bills are yellow and massively-built. Juvenile birds resemble adult [[golden eagle]]s (''Aquila chrysaetos''), and do not gain their white plumage until their fourth or fifth year. | The bald eagle is predominately blackish-brown in color, with mature adults bearing a white head and tail.
