The osprey and owls are the only raptors whose outer toe is reversible, allowing them to grasp their prey with two toes in front and two behind. This is particularly helpful when they grab slippery fish. [26] The osprey is 0.9–2.1 kg (2.0–4.6 lb) in weight and 50–66 cm (20–26 in) in length with a 127–180 cm (50–71 in) wingspan.
The eastern osprey (Pandion haliaetus cristatus) is a diurnal, fish-eating bird of prey. They live in Oceania at coastal regions of the Australian continent, the Indonesian islands, New Guinea, and the Philippines. It is usually sedentary and pairs breed at the same nest site, building up a substantial structure on dead trees or limbs.

An osprey on nest at Loch of the Lowes, Scotland. The osprey (Pandion haliaetus) is a medium-large raptor which is a specialist fish-eater with a worldwide distribution. The subspecies Pandion haliaetus haliaetus is native to Eurasia and is found in the British Isles, where it is a scarce breeder primarily in Scotland, with smaller numbers in England and Wales.
The osprey is usually placed in a separate family (Pandionidae), as is the secretary bird (Sagittariidae), and the New World vultures are also usually now regarded as a separate family or order. Karyotype data [ 3 ] [ 4 ] [ 5 ] indicate the accipitrids analysed are indeed a distinct monophyletic group.
Pandion is a genus of fish-eating bird of prey, known as ospreys, the only genus of family Pandionidae.Most taxonomic treatments have regarded this genus as containing a single living species, separated into subspecies and found worldwide near water, while some treatments recognize two living species, splitting off the eastern osprey (Pandion (haliaetus) cristatus) from Australia and southeast ...
The erection of nest platforms for great grey owls was pioneered by Robert Nero in central Canada in the 1970s. Nesting may occur from March to May. Unlike, for example, osprey or white storks, the great grey owl does not predictably re-use nest sites over consecutive years. Four eggs are the usual clutch size. Eggs average 42.7 mm (1.68 in ...
