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.
For the past two summers, Victoria Rosikiewicz has worked for Conserve Wildlife Foundation of New Jersey at the Long Beach Island Foundation (LBIF) of Arts and Sciences. LBIF is a non-profit organization whose mission is to “promote the arts and sciences on Long Beach Island and the surrounding communities by enlightening, educating, and stimulating thought and discussion about current trends in the arts and sciences through educational and cultural programs for all ages.” We began working with LBIF in 2015 to help encourage ospreys to utilize a nest platform on their 20 acre preserved saltmarsh. Over the years, our relationship has grown and we have worked to improve science based programming and environmental features on site. From enhancing their Nature Trail and installing the live streaming LBIF Marsh Cam, building the Osprey Blind, and creating terrapin nesting habitat. Victoria has helped to expand environmental education through leading LBIF’s Discovery Days public walks, CWF’s wildlife summer camp, and conducting wildlife surveys. This work has been funded through a grant from the Osprey Foundation.

This summer I had the opportunity to work as an intern for the Conserve Wildlife Foundation of New Jersey (CWF), researching and surveying Northern diamondback terrapins. Words could not describe how excited I was for this position, working with Senior Wildlife Biologist, Ben Wurst every day this summer was an incredible learning experience. Mr. Wurst taught me how to conduct surveys Great Bay Blvd Wildlife Management Area. This area is an ecological marvel, I witnessed hundreds of terrapins crossing the road on multiple occasions. I remember one day in particular when such a large quantity of terrapins were moving that it took me six hours to drive down that five-mile road, over two hundred terrapins were observed on Great Bay Boulevard that day alone.

This summer, I had the chance to volunteer for the Great Bay Terrapin Project to help survey the local terrapin population within Great Bay Boulevard Wildlife Management Area. Being able to assist a vulnerable population was incredibly fulfilling and I personally was able to learn a lot about their behavior during this incredible time. I got to see firsthand just how many female turtles crossed that road to lay their eggs, but unfortunately that also showed me just how many were injured or killed by reckless, inattentive, or outright malicious drivers. One thing I realized during this is just how hardy of an animal the terrapin is. I saw individuals with massive chunks taken out of them, bite marks, claw marks, and huge gashes from boat propellers forever etched into their shells. I realized that despite their vulnerability in early life and extremely slow growth, the defense of their shell and their insane ability to recover from injuries left them with very few threats for a long time. Even many major boat injuries are recoverable, emphasizing the severity of the threat posed by automobiles specifically.
Aerial view of an empty osprey nest. Little Egg Harbor, NJ. June 2024.
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.
Last fall I received a text from Kelly Scott, Resource Interpretive Specialist at Island Beach State Park about an osprey platform. She was kayaking within the Sedge Island Marine Conservation Zone and noticed one laying on its side – on a sandbar. I knew exactly which nest she was looking at. Later last year, I flew my sUAS to confirm her observation and make plans to get it back in working order before ospreys returned this year.

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.
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.
