Behaviour

Diet

Its diet includes medium-sized birds, mammals, and sometimes reptiles.

Breeding

Display flight is rarely seen but includes fast vertical dives as well as U shaped flight where the bird (probably the male?) starts out going down vertically on outstretched wings, gradually bending the path to the bottom of a U and ending up going vertically up, still on outstretched wings. During display, it will call in series of single whistles[2]. Also described is a display where the male and female in flight locks talons with each other[3].

They build a large stick nest on a branch of a tall tree. 1 egg is laid and incubated for 44 - 48 days. The young hawk-eagle will fledge from 9 1/2 - 13 weeks after hatching, but will stay near the nest and be fed by the parents for up to 1 year after fledging. The female Ornate Hawk-Eagle does most of the feeding of the chick while it is in the nest. The male will bring food to within a few hundred feet of the nest and give the food to the female, but usually does not feed the young.
