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.
An active osprey nest with two live and one dead nestling on the Mullica River. June 2024.
As juvenile ospreys fledge and adult females begin their southbound migration, work to summarize data from this year is ongoing. So far, it doesn’t look like a terrible year but not a great one either. Food stress (or brood reduction) was still apparent within some coastal nest colonies, despite the lack of severe weather (nor’easters/microbursts, etc) which could affect the ability of adult males to find and catch prey.

So far it has been an usual year for nesting osprey in New Jersey. This spring, the pair that has nested at our osprey cam in Barnegat Light, who arrived on time, the female did not lay any eggs. Then I heard from a woman who watches a nest near the southern end of Long Beach Island who reported the same — pair present but incubation was never observed. Another report came in from an osprey nest watcher on the Mullica River (to the southwest of LBI) who reported the same — no incubation observed. We put out a call on social media for osprey nest watchers to report anything odd like this to us (while also reporting osprey nest activity online via Osprey-watch.org). Some people reported seeing the same behavior..
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.

In coastal New Jersey, during spring and summer the recovery of ospreys is apparent. They grace the skies of most ocean front beaches from Sandy Hook to Cape May in search of prey. Their nests line our shorelines and can be found in a variety of nest structures. Today there are over 800 pairs of ospreys who nest all across New Jersey. Results from the 2023 nesting season illustrate how the osprey population continues to grow but with reduced reproductive success due to extremes in weather and reduced prey availability.

One of my favorite things about working with the NJ Eagle Project is when we receive resighting’s of New Jersey banded eagles. Especially when that eagle is in a pair and nesting. One eagle that we’ve been following over the years, is fondly named “Jersey Girl” due to her NJ origins. She was reported to us in 2014 by Linda Oughton, who has been keeping track of her and her mate since 2010.

Jersey Girl and her mate nest in Montgomery County, Pennsylvania. She was one of three chicks banded May 10th 2004 at the Hopewell West, nest which is located in Cumberland County along the Cohansey River. She was banded with green band B-64. That means that this May “Jersey Girl” will be twenty years old!
Since 2010 the pair has successfully raised and fledged a total of 20 young eagles. The pair is not yet incubating this season and Linda reports that they usually start on Valentine’s Day. The pair is well loved by neighbors and people who walk along the Perkiomen Creek, where the pair often fishes.
It’s so wonderful to know that an eagle I helped band almost 20 years ago has survived and raised 20 chicks of her own.

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.
Each year since 2017, CWF has been teaming up with partners from the USFWS New Jersey Field Office to survey the JB McGuire Airfield for grassland birds during the breeding season. Part of a long-term monitoring project, the airfield has been undergoing habitat restoration to maintain native warm season grassland habitat. The habitat restoration efforts are nearly 70% complete with roughly 700 acres seeded since 2017 and another 100 acres to be completed the following year.
Six of the ground-nesting bird species documented at the airfield are State-listed as either endangered, threatened, or of special concern. The eastern meadowlark (Sternella magna), a member of the blackbird family, is a State Species of Concern. It prefers a minimum of ten to twenty acres of unfragmented dense grasses of medium height for nesting. The State-threatened grasshopper sparrow (Ammodramus savannarum) favors patches over 100 acres containing short- to medium-height bunch grasses interspersed with patches of bare ground, a shallow litter layer and scattered forbs. The savannah sparrow (Passerculus sandwichensis), also State-threatened, requires a mix of short and tall grasses, a thick litter layer, dense ground vegetation, and scattered forbs. Another member of the blackbird family is the State-threatened bobolink (Dolichonyx oryzivorus). Bobolinks prefer to place their nests in areas of greatest vegetative height and density and could potentially nest in patches as small as five to ten acres. The State-threatened horned lark (Erimophila alpestrias) nests in areas of barren ground with short and sparse cover and are quick to abandon sites as vegetation grows thicker.
