Osprey (Pandion haliaetus), also known colloquially as seahawk, fish hawk or fish eagle, is a medium-large fish-eating bird of prey or raptor. However, It is not the same as a sea-eagle. It is found on all continents except Antarctica although in South America it occurs only as a non-breeding migrant. It is widely distributed because it tolerates a wide variety of habitats, nesting in any location which is near a body of water and provides an adequate food supply. It is divided into four similar subspecies.
Because the Osprey has many unique characteristics, it has been given its own taxonomic genus, Pandion, and family, Pandionidae. It is a medium-sized raptor, reaching 60 cm (24 in) in length with a 1.8 m (6 ft) wingspan. It is brown on the upperparts and predominantly whitish on the head and underparts, with a brownish eyepatch and wings.
As its other common names suggest, the Osprey's diet consists almost exclusively of fish. It has evolved particular physical characteristics and exhibits some unique behaviours to assist in hunting and catching prey.
