Harpia harpyja, the harpy eagle, is considered one of the largest eagles, with a wingspan of 6.5 feet (nearly two meters), rear talons up to four inches (10 cm) long, and a weight of 9 to 20 pounds (4 to 9 kg). The female is twice the size of the male. This magnificent predator inhabits the highest treetops of the canopy, an elusive hunter with legs as thick as human wrists. It feeds on sloths, two-foot-long howler monkeys, armadillos, baby deer, and even peccaries. The harpy spends two years raising just one chick, and they're threatened by severe habitat loss and other human-related activity.
