Mass Audubon State of the Birds

Find Bird Groups

Osprey
Pandion haliaetus

Thanks to extensive programs to construct nesting poles (especially in coastal areas) and the banning of DDT in 1972, the Osprey has once again become a common breeding bird in the Commonwealth. Its breeding distribution in the state remains somewhat restricted, with most birds found in coastal areas, but this is quickly changing, and inland nests are not uncommon.
