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.
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.
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.
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
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.
