It is considered a top predator that feeds on large to small mammals including monkeys and sloths. An adult harpy can grow talons up to seven inches long. This eagle can also be identified by its black chest, white underside, and plume of gray feathers that crowns its gray head. The harpy eagle nests in tall trees in the Amazon, such as the Brazil nut tree. Pairs mate every other year producing one to two chicks.
Parents raise their chicks in nests built of sticks.
This woodpecker's entire body is built for boring holes. It has a resilient sharp bill used to chisel out holes and a barbed tongue that helps it eat woodboring insects. In addition, the yellow-tufted woodpecker has strong claws and tail feathers that provide a secure and well balanced hold to a tree. Its neck muscles even absorb the shock created by the repetitive back and forth motion used in drilling. Aside from insects, the yellow-tufted woodpecker feeds on nectar and fruits in the Amazon.
