ROCKVILLE CENTRE, N.Y. (CBSNewYork/AP) – Three bald eagles, rarely seen on Long Island, have taken up residency in Hempstead Lake State Park.

The birds have been seen in the area for the past two months, according to Newsday. They’re two adults and a younger bird believed to be their offspring.

Their repeat sightings indicate they’re staying in the area rather than just flying over.

Experts said it’s very rare to see more than one bald eagle in this region.

A research chairman for the Audubon Society chapter in Uniondale says the reason for more eagles turning up on Long Island “is just population expansion” after their near extinction.

The raptors were reintroduced in New York’s Adirondacks and Catskills after facing extinction from DDT pesticide-weakened eggshells in the 1960s.

Other eagles on Long Island also have been spotted in recent years in Bayville and along the Carmans River in Brookhaven.
