One of the adaptations that help the harpy eagle be a very successful rainforest predator is it's size. They can reach 6 1/2 feet and weight up to 20 pounds. In this way, the harpy eagle can hunt animals that are abundant in those forests, such as primates, sloths or even small deer.
Another adaptation is it's talons which can reach 5 inches. These huge talos help them get their preys and perch in a secure way as there is lot of vegetation there.
Lastly, they have small wings compared to their size, this helps them maneuver in the forest density.
