2010 Osprey Information for NJ

Ospreys are well-loved birds of our coastal bays and marshes. Formerly known as the fish hawk, ospreys rely almost exclusively on fish for their diet. They have taken well to human structures, such as duck blinds and channel markers, for nest structures. They, like eagles and falcons, succumbed to the effects of DDT and their population dropped to about 60 pairs by the early 1970s.

With the help of biologists and, more recently, volunteers who put up nest structures, they have recovered to more than 360 nesting pairs. The Endangered and Nongame Species Program monitors their health as an indicator of many coastal species, as they are sensitive to contaminants and the viability of the aquatic food chain.
