Photos from the Field: Peregrine Falcon Nestbox Installation in Trenton

Meeting our goals…we can only hope!

by Ben Wurst, Habitat Program Manager

In 1993-94 six young peregrine falcons were released at 20 West State Street (Mary G. Roebling Building) in Trenton to help bolster the population of urban nesting falcons in the area. Currently the closest nest is 20 miles away at the Tacony-Palmyra Bridge (where they also have a camera at the nest). Twenty years later and we may finally get some nesting falcons in Trenton! It all started when Jean Bickal, a worker in the building, noticed a falcon that often perched on the building ledges. From there Kathy Clark, a Zoologist with New Jersey Division of Fish & Wildlife made a site visit and took measurements to see if we could fit a nestbox (dog igloo) out a window on the 10th floor, which also had a roof on it. It appeared one would fit so we setup a date to install the new nestbox.

 

Cities and urban areas actually provide suitable habitat for falcons. Urban areas usually have lots of ledges under bridges or on buildings for them to nest, and abundant prey, in the form of pigeons and other songbirds. In New Jersey we have three other pairs that nest on buildings in Jersey City, Elizabeth, and Atlantic City, plus pairs that nest on the Tacony-Palmyra, Walt Whitman, Betsy Ross, and Burlington-Bristol Bridges.

 

On February 5th we helped install a new nestbox on top of a roof at 20 W. State St. We’re hoping that the falcon seen that day will find a mate and use the nestbox to raise young. Fingers crossed that we get some good news soon!
