The Harpy Eagle is the largest eagle in the western hemisphere,
native to southern Mexico through most of the northern half of South America.
For its size and weight (up to 9 kg for females and 5 kg for males),
its wingspan is relatively short at 6 foot to 6' 7" to negotiate the trees, since it lives high in the tree canopy.
The Harpy will take prey as large as big macaws, monkeys and even sloths.
Male and female have similar plumage and are particularly striking when they raise their head crests.
