Several osprey have returned from South America to Maine’s Wolfe’s Neck Woods State Park, another sign that spring has arrived.

Park Manager Andy Hutchinson says one pair has set up nest-keeping on Googins Island, while another male has returned to a mainland site. He says the male’s mate should return by Monday.

The birds have become a favorite attraction at the seacoast park in Freeport.

Osprey are one of the largest birds of prey in North America and eat fish almost exclusively. They were once an endangered species but are now found on all continents except Antarctica.

Osprey build nests on high trees and manmade structures. They mate for life, though if a mate dies, the remaining bird will find a second mate. Osprey can live 15 to 25 years.
