Eagles: A Guide to Majestic Birds of Prey
This article explores the diverse world of eagles, detailing their characteristics, habitats, and behaviors. Eagles, members of the Accipitridae family, are renowned for their size, strength, and striking appearances.
The Bald Eagle (Haliaeetus leucocephalus):
The bald eagle, distinguished by its white head and neck feathers, is a prominent symbol of the United States. Adults typically measure around 40 inches in length with wingspans of 6-7 feet. Their plumage is characterized by a dark brown body and a stark white head and tail. Immature eagles are entirely brown, with some white markings on their tails and wing linings. They have yellow beaks, eyes, and feet.
Bald eagles inhabit areas near rivers, large lakes, and coastal regions throughout the world, excluding South America. These eagles primarily feed on fish, often following seabirds to locate their prey. They are also known to steal catches from other birds, and scavenge on carrion. This species was once endangered, with breeding sanctuaries in Florida contributing to a population recovery. They build their nests in tall trees, constructed from bulky platforms of sticks, and typically lay 2-3 white eggs per season.
The Golden Eagle (Aquila chrysaetos):
Golden eagles, named for their golden appearance, belong to the hawk family and possess wingspans spanning from six and a half to seven and a half feet. They can live for 30 or more years. Adults are evenly dark below or with some lighting at the base of the tail. Immature golden eagles display a white flash in the wing at the base of the primaries, and a white tail with a broad dark terminal band.
Golden eagles are found in the mountainous regions of the Northern Hemisphere. They are partial migrants and feed on rodents, snakes, birds, and even deer and sheep. They are fully protected by law. Golden eagles construct nests, sometimes reaching ten feet across, on cliffs overlooking their hunting grounds. They often reuse these nests for generations and lay 2-3 spotted eggs per season.
