This is a list of the fauna of Finland. Finland borders Sweden to the west, Russia to the east, and Norway to the north, while Estonia lies to its south across the Gulf of Finland, allowing an ecological mix. Finland contains many species of mammals, birds, and fish, but only a few reptiles and amphibians. This article discusses all the vertebrate animals which can be found on Finland itself, not the oceans.
The Osprey (Pandion haliaetus), sometimes known as the sea hawk, fish eagle or fish hawk, is a diurnal, fish-eatingbird of prey. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts, with a black eye patch and wings.
The Osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica although in South America it occurs only as a non-breeding migrant.
As its other common name suggests, the Osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomicgenus, Pandion and family, Pandionidae. Four subspecies are usually recognized, one of which has recently been given full species status (see below). Despite its propensity to nest near water, the Osprey is not classed as a sea-eagle.
