Peregrine Falcon Cameras
This camera is down for maintenance.
“The Falcon Cam is a wonderful opportunity to observe and study one of nature’s most fierce and fascinating creatures,” said Union County Freeholder Chairman Bruce H. Bergen. “It provides an enriching experience for County residents of all ages, and for online visitors from all over the world.”
“Peregrine falcons are listed as an endangered species in New Jersey, and Union County has been part of ongoing efforts to ensure the survival of these remarkable birds statewide,” said Freeholder Vice Chairman Sergio Granados, who is a member of the Parks and Recreation advisory board. “The live feed will help build an appreciation for the role that we can all play in preserving our natural heritage, both in our parks and in the urban environment.”
Peregrine falcons are the fastest creatures on Earth. They are known for their rapid dives, which can approach an astounding 200 miles an hour as they move in on their prey.
Union County’s falcon preservation efforts have been undertaken with the generous assistance of wildlife experts from New Jersey DEP and the nonprofit Conserve Wildlife Foundation of New Jersey.
The Conserve Wildlife Foundation is Union County’s official partner for educational programming related to falcons and the Falcon Cam.

Union County Peregrine Falcon Timeline
- Two falcons, a male and a female, try to establish a nest on the 14th floor ledge of the 17-story County Courthouse in midtown Elizabeth.
- Leg bands reveals that the female was born in Jersey City and the male was born in Connecticut.
- The choice of location in the center of a bustling mid-sized city may seem odd, but they are likely attracted by the height of the ledge and the ample supply of prey nearby.
- Unfortunately, windy conditions are an obstacle and the attempt is unsuccessful.
- Acting on the guidance of wildlife experts with the New Jersey Department of Environmental Protection, County and State workers install a repurposed igloo-style dog house on the west side of the Courthouse roof to protects eggs and chicks from the elements.
- Falcons have successfully raised chicks in the same nest every year from 2006 to 2016.
- Sometime during this period an unbanded male replaced the banded male from Connecticut.
- February 2016: Two webcams are installed at the nest by Union County with guidance from the New Jersey Division of Fish & Wildlife and Conserve Wildlife Foundation. One is located inside the nest box and the other is fixed on an outside railing to capture nesting, hatching and fledgling behaviors. The outer camera can be moved by remote control, and the inner camera includes an infrared feature for night viewing.
- At some point during 2016 the Jersey City female is replaced by a banded six- year-old female. She was born at Throg’s Neck Bridge in New York City.
- Spring 2016: The pair raise three hatchlings from four eggs.
- Summer 2016: A banded chick from Union County’s 2016 clutch is found dead in Key West, Florida. The probable cause of death is electrocution due to contact with power lines, a common source of bird mortality.
- September 2016: Union County signs a Memorandum of Understanding with Conserve Wildlife Foundation for the purpose of “educating the public about peregrine falcons, their habitats and the importance of protecting rare species of wildlife.
- Fall 2016: A third camera is installed on the Courthouse roof to track activity on the east side of the courthouse roof.
- December 25, 2016: The Throg’s Neck female is seen on camera for the last time.
- December 28, 2016: An unbanded female replaces the Throg’s Neck female.
- February 2017: The male falcon and the unbanded female continue to bond at the nest site. Video 1 | Video 2
- Late February: A second female is spotted on the falcon cam. This female has a leg band identifying her as 91/BA, who came to Union County all the way from Rochester, New York. Drama ensues as she attempts to claim the nest site. This distraction could possibly cause a delay in mating and breeding. Video
- March 22: The unbanded female lays her first egg.
- March 25: The unbanded female lays her second egg
- March-April: After a protracted battle 91/BA establishes claim over the nest.
- Earth Day -- April 22: At approximately 1:59 p.m. 91/BA lays an egg of her own, making a total of three in the nest.
- April 24 and April 27: 91/BA lays two more eggs, for a total of five. The male and 91/BA are sharing incubation duties for all five eggs together.
- May 8: All five eggs are still being incubated together but the two older eggs were expected to hatch over the weekend. They are now considered nonviable, most likely due to inconsistent incubation during the territorial battle between the unbanded female and 91/BA.
- May 30 and 31: The first (video) and second eggs successfully hatch. The parents are busy feeding the two young "eyas" (video) while continuing to incubate the three remaining eggs.
Nesting Behavior and Terminology
Most peregrines nesting in New Jersey are resident birds that remain near the nest site throughout the entire year. Courtship begins in earnest during March with aerial displays and the male (‘tiercel’) bringing food to the female (‘falcon’). Peregrine nests, known as ‘scrapes,’ consist of a simple depression in a gravel substrate. Egg laying occurs between late March and the end of April when the female will deposit a clutch of three to four eggs. Incubation occurs only after all of the eggs have been laid and lasts 32 to 33 days. The female usually performs most of the incubation responsibilities with the male occasionally participating. After hatching, the young are totally dependent upon their parents (altricial) until they are ready to fly in approximately seven weeks. Upon leaving the nest (fledging), the young remain dependent on the adults until they master their flight and hunting skills. Source: New Jersey Department of Environmental Protection.
In 2015 only 24 nesting pairs of peregrine falcons were reported in all of New Jersey. Of that total, only 16 are known to have made their homes in buildings like the County Courthouse.
The Union County Falcon Cam is one of only two in New Jersey. The other one is located in Jersey City.
Union County participates in a banding program with wildlife experts from the New Jersey Department of Environmental Protection. Thanks to the partnership, offspring from the County Courthouse pair have been observed around the tri-state region, where they have raised chicks of their own.
Until recent years, the peregrine falcon population was in steep decline along with other birds of prey due to habitat loss and the pesticide DDT. By 1964, peregrine falcons disappeared completely from New Jersey and all other states east of the Mississippi River.
Peregrine falcons were one of the first birds to be the focus of conservation efforts after the 1960’s.
In the 1980’s an intensive re-introduction effort began in the tri-state region. Since 2000 the New Jersey population has stabilized at approximately two dozen nesting pairs annually.
