The ornate hawk-eagle (Spizaetus ornatus) is a bird of prey from the tropical Americas. Like all eagles, it is in the family Accipitridae. This species is notable for its vivid colors, which differ markedly between adult and immature birds.
This is a medium-large raptor, at about 56.0–68.5 cm (22–27 in) in length, 117–142 cm (46–56 in) across the wings, and weighing about 960-1,650 g (2.1-3.6 lbs). It has a prominent pointed crest, raised when excited, a black bill, broad wings, and a long, rounded tail.
The typical adult has blackish upper parts and crown, bright chestnut sides to the neck and breast, and a black-edged white throat and central breast. The rest of the under parts and feathered legs are white barred with black, and the tail has broad black bars. The under wings are white, with barred flight feathers; due to the heavy pattern, birds usually look rather dark in flight.
Sexes are similar, but young birds have a white head and under parts, with a grey crest, brown upper parts, and barring only on the flanks and legs.
The call is a high-pitched whee-oo whee-oo. source
