Back in the 1970s, things weren’t looking great for osprey populations. There were just 75 known pairs living on Long Island at the time. The widespread use of the insecticide DDT had taken its toll on the birds, who ingested it through the fish they ate, resulting in thinning eggshells that were often crushed during the incubation period.

But after the banning of DDT and changes in environmental regulations, the birds’ numbers began to rebound. The Group for the East End had a major hand in helping the ospreys make a comeback through the installation of nesting platforms across the region.

This week, Bob DeLuca, president of Group for the East End, joins the editors to talk about the ospreys’ journey back from the brink of extinction and the upcoming monitoring program, where some 500 osprey nests across the East End will be visited.
