This impressive raptor is one of the largest eagles in the world, weighing an average of 18 pounds. With its 7-foot wingspan, the harpy eagle is designed for speed and agility high up in the forest canopy. This short wingspan helps them navigate through thick forest trees. The harpy hunts monkeys, sloths, iguanas, and some birds with its talons that measure five inches in length. Unfortunately, the harpy eagle is threatened by large scale deforestation and even more so by being hunted.
