Raptors in New Jersey

From One to 135 - New Jersey's Bald Eagle Success Story (US FWS site)

Raptors, commonly referred to as "birds of prey," include hawks, owls, eagles, falcons and vultures. Raptors have fascinated people for thousands of years and inspire people even today. Fortunately, after some frightening declines in some of our largest species, raptors represent some of New Jersey's greatest success stories.

The bald eagle, osprey and peregrine falcon have made impressive comebacks from the brink of extinction, in large part thanks to the efforts of division biologists. Unfortunately, not all species of raptors are thriving - the American kestrel, for instance, has experienced a sharp decline in recent years, and the work of biologists in the Endangered and Nongame Species Program continues.

The links below lead to pages with information about some of these magnificent birds.

Bald Eagle Information

The bald eagle is a shining example of recovery in New Jersey. In 1973, when the Endangered and Nongame Species Conservation Act was passed, there was just one nesting pair, in a remote forest in Cumberland County.

Today there are more than 100 nesting pairs of eagles in the state. Most are in the Delaware Bay counties of Cumberland and Salem, but eagles can now be found statewide. Additionally, numbers of wintering eagles along the Delaware have increased dramatically. They remain on the state endangered species list (threatened federally), however, due to their sensitivity to environmental contaminants, habitat loss and human disturbance. The challenge to biologists and citizens now is protecting the lands and waterways used by eagles to maintain and enhance this species' recovery.

Peregrine Falcon Information

Peregrine falcons, as the fastest bird in the skies, have fascinated people for centuries. Peregrine numbers fell due to the effects of DDT which caused their eggs to fail, and they became extinct east of the Mississippi by 1964. They were one of the first birds to be the focus of conservation, however, and through an intensive reintroduction program, returned to the skies in New Jersey and other eastern states in the 1980s.

The population in New Jersey has been about 20-24 pairs annually since 2000. In 2003 peregrine falcons returned to their historic cliff nesting habitat on the Hudson River Palisades – a huge milestone in the peregrine's recovery in the state and the region.

Osprey Information

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 500 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.

American Kestrel Information

This once-common inhabitant of fallow fields and pastures has declined in recent years, and the reasons are largely unknown. In February, 2012, the American kestrel became listed as a State Threatened species. Below are links to some of the work ENSP has been conducting on this falcon.

2004 American Kestrel Survey (pdf, 334kb) The Endangered and Nongame Species Program embarked on a survey campaign in 2004, and the findings were alarming.

In 2006, ENSP started working with Dr. John Smallwood from Montclair University. Dr. Smallwood has run a successful kestrel nest box program since 1995 in northwestern New Jersey. One result of this collaboration was an article in a special issue of the Journal of Raptor Research focusing on American kestrels, American Kestrel breeding habitat: The importance of patch size (pdf, 375kb).

Using Dr. Smallwood’s nest box program as a model, ENSP started a nest box program in 2006 (NJDEP Map Contest poster summarizing ENSP kestrel work). To further test the importance of patch size, ENSP placed nest boxes in habitat patches of different sizes and tracked their use by kestrels. The results of this study as well as a summary of the nest box program can be viewed in the New Jersey American Kestrel Nest Box Project 2006-2012 report (pdf, 3.6mb).

In December of 2012, ENSP presented a poster at the ESRI Mid-Atlantic User Group Conference, American Kestrel Habitat Loss and Fragmentation (pdf, 1.9mb). The poster summarizes American kestrel habitat within New Jersey over a 21 (1986-2007) year period.
