The bald eagle is placed in the genus Haliaeetus (), and gets both its common and specific scientific names from the distinctive appearance of the adult's head. Bald in the English name is from an older usage meaning "having white on the face or head" rather than "hairless", referring to the white head feathers contrasting with the darker body. [4]
Eagle is the common name for the golden eagle, bald eagle, and other birds of prey in the family of the Accipitridae. Eagles belong to several groups of genera, some of which are closely related. True eagles comprise the genus Aquila. Most of the 68 species of eagles are from Eurasia and Africa. [1]
Mountain hawk-eagles often live in cooler, more temperate habitats including deciduous forest than other hawk-eagles. Both the northern and southern limits of this widely found raptor are surprisingly poorly known to this day, with historic records suggesting that the species may take up residence hundreds of kilometers north of its accepted ...
Golden eagles are very hardy species, being well adapted to cold climates, however they cannot abide declining available food sources in the northern stretches of their range. Eagles raised at latitudes greater than 60° N are usually migratory, though a short migration may be untaken by those who breed or hatch at about 50° N. [81] During ...

[204] [205] [206] Given their larger population and farther current range into warmer areas (whereas the modern white-tailed eagle is only common in cold, northern climes), bald eagles (the ecological equivalent of the white-tailed eagle in North America) have a considerably broader prey spectrum than white-tailed eagles that ranges well over ...
Bald eagle populations are now recovering after years of hunting, habitat destruction, and pesticide-induced deaths. In the early 1970s, Colorado had just one breeding pair of bald eagles but by 1993 biologists counted 19 breeding pairs. In Wyoming nesting attempts increased from 20 in 1978 to 42 in 1988.
Northern New South Wales eagles were able to produce 0.8 young per pair from 2005 to 2006 while 0.89 and 0.64 fledged young per pair per year was the fledgling rate in central and western New South Wales, respectively.
