New Jersey had only about 50 osprey pairs in the 1970s; biologists built nest platforms and moved eggs, and by 2023 the state counted 800 occupied osprey nests

Osprey populations in New Jersey rose from about 50 nests in the 1970s to an all-time high of 800 nests. The drastic increase is attributed to conservation efforts and the ban of the pesticide DDT. Biologists have implemented successful interventions, including providing artificial nesting platforms for these birds. While the population is now considered stable, continued monitoring is essential to ensure their wellbeing.
