The Osprey is often seen flying over the water, hovering, and then plunging feet-first to catch fish in its talons. Its diet consists almost entirely of fish. Typically feeds on fish 4-12" long. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey is unusual in that it is a single living species that occurs nearly worldwide.

Pandion haliaetus

Diet

  • Feeds almost exclusively on live fish, which make up over 99% of its diet.

  • Common prey includes mullet, tilapia, trout, bass, catfish, herring, and many other freshwater and marine fish.

  • Hunts by hovering or soaring over water before making a dramatic feet-first plunge, sometimes completely submerging to seize fish with its powerful talons.

  • Possesses specialized adaptations for fishing, including reversible outer toes and spiny foot pads that help grip slippery prey.

Range

  • Found on every continent except Antarctica, making it one of the world's most widespread birds of prey.

  • Breeds throughout Canada, the United States, Europe, and much of Asia.

  • Winters along the coasts and inland waters of Mexico, Central America, the Caribbean, South America, Africa, southern Asia, and Australia.

  • In Mexico, including the Zihuatanejo region, it is a common winter visitor and migrant, especially around estuaries, coastal lagoons, rivers, reservoirs, mangroves, and beaches. A few birds may remain year-round.
