Predation
The Harpy Eagle is an apex predator in every rainforest it inhabits, and has no natural predators meaning they are very predatory and protective towards their territory and nest. When threatened, Harpy Eagles have been known to grab predators within its nest's radius, fly to a high altitude and drop them, resulting in an all most definite kill in an attempt to protect their young. Harpy Eagles are patient hunters, and will regularly be observed waiting in the canopy of a tree for their prey. They will almost never miss a chance for a potential kill.
Behaviour
Harpy eagles are most often found in pairs as they are monogamous meaning they have only one mate for life.Using their extraordinary vision, they are able to spot arboreal(animals living in trees) prey from long distances. Harpy eagles can potentially perch (sit and rest on a tree branch) for up to 23 hours when searching for their prey. Having adapted incredible flying maneuverability, Harpy Eagles have no problem navigating through their rainforest habitat. They are diurnal animals meaning they hunt only at day.
Communication and Perception
Harpy eagles use vocalizations to communicate with one another.They often produce vocalizations in a form of a screech or chirp while sitting on perches. This is believed by biologists to be territorial behavior. Pairs of harpy eagles will often rub their bills together, which is believed to be part of mate bonding. Like all birds, harpy eagles perceive their world through visual, tactile and auditory stimuli.
