There are four subspecies of ospreys, which are separated by geographic region.
This is Pandion haliaetus haliaetus (with a clear breast band) which breeds in Europe, North Africa and Asia (north of the Himalayas) and winters in South Africa, India and the East Indies.
Ospreys 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 which is particularly helpful when fishing.
