Harpy eagle

Harpy eagles range from Mexico to northern Argentina and live in forested areas. Despite their wingspan, which can reach up to 6.5 feet (2 meters) across, harpies fly through their forest home with great agility. For nesting, harpies favor silk-cotton trees (kapok trees) and usually build nests 90 to 140 feet (27 to 43 meters) above the ground. They like to use trees with widely spaced branches for a clear flight path to and from the nest. Harpies use large sticks to create the nest's huge frame and line it with softer greens, seedpods, and animal fur to make it warm and comfortable. A harpy nest measures about 4 feet (1.2 meters) thick and 5 feet (1.5 meters) across, large enough for a person to lie across! Once built, an eagle pair may reuse and remodel the same nest for many years.
