Osprey

The osprey's diet consists almost exclusively of fish. Prey is first sighted when the bird is 10–40 m (33–130 ft) above the water, after which the bird hovers momentarily then plunges feet first into the water. The osprey is particularly well adapted to this diet, with reversible outer toes, sharp spicules on the underside of the toes, closable nostrils to keep out water during dives, and backwards-facing scales on the talons which act as barbs to help hold its catch.
