2024 Eagle Project Get-together; photo by: Kathy Clark
We can never thank the NJ Eagle Project volunteers enough for all they do to monitor and protect eagles in New Jersey. Conserve Wildlife Foundation hosted a get-together at the Assunpink Conservation Center this August as a way to say, “thank you”. There are 162 eagle project volunteers currently monitoring eagle nests statewide and it’s not always easy to get everyone together at one time due to distance and obligations. The volunteers who were able to attend shared stories with other volunteers about the nesting season, received an update on the proposed eagle delisting from ENSP Chief, Kathy Clark and hopefully felt very appreciated. This is down time for the eagle project volunteers, though some eagles are already back and working on their nests. THANK YOU to all the Eagle Project Volunteers.

The Bald Eagle project would not be possible without our corporate partners. We would like to thank PSE&G, Wakefern/ShopRite Stores, Wells Fargo Advisors, and the Cape May County Zoo (AAZK) for providing crucial financial and outreach resources to help keep bald eagles soaring above New Jersey.
The 2024 NJ Bald eagle nesting season is winding down and so far 221 young eagles have fledged from nests throughout the state. We know that these eagles have fledged due to the eagle project volunteers who monitor all known eagle nests in New Jersey. Being a nest monitor can be a joyful experience when all goes well and the pairs successfully fledge young. But, it can also be heartbreaking when a pair fails to hatch eggs and when adults or chicks are lost during the season. Despite the ups and downs of monitoring eagle nests the volunteers continue to be dedicated to the eagle project. I asked the Eagle Project volunteers to send me their two favorite photos from the season.
Please enjoy the slideshow.
All photos were taken by trained volunteers from a safe distance using high powered scopes and cameras.

New Jersey is home to three native falcon species, the peregrine falcon, merlin, and American kestrel. Falcons are fierce predators known for their swift flight and intensity. Of these species, I am always most excited to spot an American kestrel.
These small falcons, roughly the size of a mourning dove, are the smallest falcon species in North America. They thrive in habitats with short vegetation such as parklands, meadows, and agricultural areas. Here, they hunt for insects and small animals like mice and voles. You can often see them perched on wires or branches, scanning for prey with their distinctive tail-bobbing behavior. They nest in tree cavities or specially placed nest boxes near fields and meadows.
Recently, I had the privilege to join New Jersey Fish & Wildlife’s (NJFW) Endangered and Nongame Species Program’s American kestrel monitoring team at a nestbox site to band young kestrels. The NJFW American kestrel project works with volunteers to monitor nest boxes in New Jersey and gather critical data about this species. American kestrels were designated as a State threatened species in 2012. While there is still a lot to learn about their decline, it is understood to be at least partially due to habitat loss and a lack of nesting sites. NJFW has been monitoring these small falcons to learn about their decline and support their recovery.

There aren’t many times when you get to climb to the roof of a courthouse in a major metropolitan area. Except if you’re a raptor biologist! We recently joined NJ Fish & Wildlife’s Chief of the Endangered and Nongame Species Program, Kathy Clark and Union County staff and guests to band the four young falcons produced at a nest atop the Union County Courthouse, home to the Union County Falcon Cam.
During the 2020 NJ Bald Eagle nesting season the Camden B pair hatched and raised two chicks. This nest was located along the Cooper River, in Camden County on a small parcel of undeveloped land in a very urban area.

On June 5, we received notification that the nest had fallen from the tree during a storm, at that time the two chicks were approximately nine weeks old. They were too young to fly since eagle don’t fledge until at least 11 weeks of age. At nine weeks of age they are the size of an adult eagle so they would be noticeable on the ground. Despite an extensive search by staff and volunteers there were no signs of the two nestlings.

Local wildlife rehab centers were notified in case the young eagles were found and brought in for care. At that point we could only speculate on their fate. Then on June 28, NJ Division of Fish & Wildlife Law Enforcement was alerted to eagles being held in a dog pen at a residence in Camden. NJDFW Conservation Officers visited the home and found the two missing eagle chicks. At this point the young eagles were twelve weeks old and should have fledged if they were still in the nest.

The eagles had been kept in the basement and fed hotdogs and chicken. Fortunately for the chicks they were moved outside and an alert citizen reported the captive eagles. They were taken to Tri-State Bird Rescue & Research for evaluation and treatment. After a week in rehab it was determined that they were healthy enough to be released. By this time the adults were no longer actively in the area of the nest tree. After eagle chicks fledge they still spend a few weeks in the nest area with the adults, learning to survive on their own. It was decided to release the two eagles in a remote area of Cumberland County. On July 9 the two Camden eagles were released at the site.

Staff and volunteers temporarily provided supplemental food (fish and road-killed mammals). The release area has a large population of juvenile and sub-adult eagles who could provide the social learning the young eagles needed. A trail camera was set up at the food drop. E/97 wasn’t seen again at the release site. Her sibling, E/96 was seen in the area several times after her release.
On March 18th, 2024, Kathy Clark with NJENSP received an email from Jerry amEnde regarding a green banded eagle he photographed at Bombay Hook NWR in Delaware.
The banded eagle was E/97! We are thrilled to know that despite her not having a “traditional” start to her life, she has to survived to become a gorgeous four year old eagle.
The NJDEP Fish & Wildlife’s Endangered and Nongame Species Program and Conserve Wildlife Foundation of New Jersey have published the New Jersey Bald Eagle Project, 2023. The NJ eagle population continues to thrive. During the 2023 nesting season, 286 nest sites were monitored of these 255 pairs were active (laid eggs). This is a slight increase of 5 active nests from 2022. This season 309 young eagles were documented to have fledged, this number is a down from 2022’s high of 335 young fledged. The productivity rate of 1.28 young per active nest is above the 1.0 young per nest needed for population maintenance.
Fifty-four nest failed to fledge young this season, this means that the pair laid eggs, but the eggs failed to hatch or the chicks did not make it to fledging. There could be many reasons for nest failure including weather events, nest/tree collapse, disturbance by humans or intruder eagles. The NJ eagle population is doing well but they still need monitoring and protection. There is constant pressure for development in NJ and if we don’t know about a nest we can’t help to protect it. Eagles are nesting in all 21 NJ counties, from remote marshes in southern New Jersey to suburban neighborhoods. How the ENSP and CWF protects these nests is on a nest by nest basis. We couldn’t do this without the dedicated group of 150 NJ Eagle Project volunteers who not only monitor the eagle nests, but help minimize disturbance to nests by educating the public about NJ’s eagle population.

The 2024 NJ Bald Eagle season is underway with eight pairs currently incubating. A great way to see what goes on in an eagles nest is to watch the Duke Farms eagle cam. The female should be laying the first egg any day now.
We’d like to thank all the volunteers, sponsors, donors and friends of the NJ Eagle Project
Two peregrine falcon eyases after being banded at a nest in southern New Jersey.
It’s no surprise to hear that peregrine falcons have made a remarkable recovery since being extirpated from New Jersey in the mid-1960s. From the cliffs of the Palisades to bridges and buildings in our urban areas and along our entire coast, peregrines can be seen at many locations throughout the state. Today the population has been holding steady with 40 (known) pairs and at least 35 active nests over the last couple years. This is due to protection through the Endangered Species Conservation Act, where biologists worked tirelessly to jumpstart their recovery efforts by “hacking” young falcons and the banning of harmful pollutants, like DDT.
The Three Bridges eagle cam went live for the 2024 nesting season on December 1st. A pair of eagles made an appearance that morning. The Three Bridges nesting platform was used by eagles in 2021, when they successfully raised two young. During the 2022 and 2023 nesting seasons, the pair were seen at the nest platform but ended up using a nest in a tree. We will see if the pair decides to use the nest platform this season. For now we believe that the Three Bridges pairs territory is both the nest tree and platform. As the numbers of nesting Bald Eagles continues to increase New Jersey there is the possibility that a second eagle pair could nest at the platform. Last nesting season there was lots of eagle action at the tower, eagles of all ages stopped by along with many different avian species. A pair of Osprey’s took interest in the nest platform but didn’t end up laying eggs. An American Kestrel perched at the platform on the first day the cam was live. It’ll be interesting to see what activity occurs at the tower this season.

Last week I attended the APLIC (Avian Powerline Interaction Committee) workshop hosted by PSE&G. APLIC is a group that leads the electric utility industry in protecting avian resources while enhancing reliable energy delivery. We all use electricity and power lines are needed to distribute the power to where it’s needed. Powerlines and transmission towers have become a normal part of the landscape and we don’t pay much attention until our power goes out. All different species of birds, from bald eagles to starlings, interact with powerlines, poles and towers daily, including perching and nesting on them.

With these interactions come issues, birds can be injured or die from electrocution and collisions which can cause power outages. Nests on poles and transmission towers can create problems with outages and fires as well as risk to chicks or adults. One part of my job is keep track of all reported injured or dead bald eagles in New Jersey. In 2023 there have been fifteen confirmed eagle electrocutions. Any recoveries that are a suspected electrocution or collision with a powerline are reported to the appropriate utility company. CWF and the NJ ENSP have a good relationship with the Utility companies in New Jersey. Each utility company has biologists that work on environmental issues including avian. There are a whole set of issues that they need to be taken into consideration when deciding how best to minimize negative avian interactions. The solutions require time, money and often scheduled power outages. When an area of lines or poles are identified as a risk for bird electrocution/collision, they are made as avian safe as possible. When new distribution lines are rebuilt, avian issues are taken into consideration and the appropriate measures are implemented.
There are quite a few bald eagles and ospreys that nest on poles and transmission towers throughout New Jersey. Most of these nests don’t cause problems, but if they need to be removed, the utility company works to obtain the proper permits and replace the nest with a new nesting structure in close vicinity. One example is the Three Bridges eagle nest. PSE&G needed to replace the entire distribution line where an eagle pair had been nesting on one of the towers for years. After much planning and coordination the nest was removed and placed on a nest platform installed on one of the new towers.
I certainly learned a lot at the workshop and gained a new appreciation for everything that goes into keeping our electricity flowing at the flick of a switch and making sure that avian species stay safe at the same time.
Barn Owls (Tyto alba) are one of the most widespread avian species in the world. Despite this impressive distribution, their numbers have been decreasing in parts of their range, and New Jersey is no exception. The barn owl population in New Jersey is in decline due to habitat loss associated with urban sprawl and development of former agricultural lands. Little is known about the Barn Owl population in central New Jersey. Through a grant from the Monmouth Audubon Society, Conserve Wildlife Foundation of New Jersey is partnering with Monmouth County Park System and the New Jersey State Park to construct, install and monitor three barn owl boxes. By providing suitable nest site opportunities we can potentially boost the barn owl population locally within Monmouth County as well as regionally as fledglings disperse to find their own nesting areas.
The first step of the project has been completed. CWF biologist Christine Healy and her Father Jim Healy have constructed three nest boxes that are ready for installation.
