The New Jersey Bald Eagle nesting season is finished for the year, so both the eagles and volunteer nest monitors now get a few months rest.  Conserve Wildlife Foundation and the NJ ENSP hosted the annual eagle volunteer get-together at the Assunpink WMA this past Saturday.  Forty-five volunteers attended and enjoyed discussing the season with fellow nest monitors and NJ eagle project staff.

On behalf of the NJ Eagle Project we thank all the 160 nest monitors who are dedicated to monitoring and protecting the NJ bald eagle population.

Thank you to Barb & Rick McKee for providing sandwiches and everyone who generously brought delicious side dishes and desserts to share.

The 2025 New Jersey Bald Eagle nesting season is finished. We are still gathering up the data for the final numbers which will be published in the annual NJ Bald Eagle Project Report. The 160 eagle project nest monitors spend countless hours monitoring eagle nests through out New Jersey. I’ve asked the nest monitors to share two of their favorite photos from the 2025 nesting season. Enjoy.

Earlier today, we joined our partners from Union County and NJDEP Fish & Wildlife to band the four young peregrine falcons produced at the Union County Courthouse in downtown Elizabeth. The four eyases are right around four weeks old and prime age for banding. After ascending to the roof, viewers of the live stream on YouTube watched as we carefully bagged each nestling and brought them inside the building.

I recently headed home from eagle nest checks near the Delaware River.  As usual, I was on the lookout for interesting raptor sightings, especially eagles.

I spotted a beautiful sub adult eagle perched along the South Branch River.  I pulled over, took out my camera, and got some great photos of this gorgeous bird.  I guessed it might be 4 years old because of the amount of white on its head.  Could this be one of the eagles from the local nests?  We have long suspected that fledglings return to their natal area. We had proof of this while tracking “Duke”, the 2019 banded eagle from Duke Farms, who had a solar tracker backpack attached. He returned frequently to his natal area. While I watched this eagle, it took off and even more exciting, I spotted a green NJ band on its right tarsus!!  Unfortunately, when I downloaded the photos, I could not make out the number of this NJ banded eagle.

I sent photos and a description of its location to all the knowledgeable and experienced Eagle Project volunteers in my area of Central NJ.  I also notified a couple of local (and always very helpful and supportive) interested supporters in the area who are “unofficially” part of the Eagle Project.  I am so thankful that everyone in our group works together for the benefit and protection of our eagles!  There is no possessiveness, jealousy, or one-upmanship, just help, support, and encouragement!

I had confidence that with this group, someone was sure to spot something!!  Imagine my absolute surprise and delight when Steve, a talented and devoted local eagle watcher emailed the group that he had found “my” sub adult and gotten a clear image of her green band:  H22!!  She is one of “mine” which I held at banding in 2022. I was overcome with emotion and excitement!  I would never have known that H22 was alive and thriving if not for Steve’s search and photos. Right on cue, Mary Ellen, another Eagle Project volunteer produced emails and photos that I had sent to the group after the 2022 banding showing H/22 as a 6-week-old nestling.  How heartwarming it was seeing her again as a nestling!

What a joy it is knowing that she is still living and healthy.  I still can’t believe that an eaglet that I held is the same one I saw as a thriving three-year-old. Hopefully she will stick around our area, avoid dangers, find a mate, build a nest, and raise her own eaglets in about 2 years’ time!

I monitor a bald eagle nest located in Wawayanda State Park, Sussex County. My heart sank when I was asked to retrieve the carcass of a bald eagle found dead on nearby Highland Lake. The Wawayanda eagles protect a large and rugged territory that includes many smaller ponds, several swamps and other wetlands, and seven lakes, including those in my community. I feared that the dead eagle was one of the Wawayanda pair. Despite their territory’s size, our local eagles are in some ways easy to follow. When the lakes are frozen, as they are this winter, we see few visiting eagles traveling through. Although eagles appear similar, each eagle is really an individual in look and behavior. After watching them closely for years, I’ve learned a lot about the eagles; characteristics, their habits, and their favorite places to perch. Moreover, the male is banded and wears distinctive green and silver ankle bands, which stand out even from a distance, especially with a pair of binoculars.

Bald eagles banded in New Jersey receive two separate bands – a silver band from the federal US Fish and Wildlife Service with a unique six-digit ID number and a state green band with a two-digit code etched in silver. Because of its color and the shorter code, the state band can be read from a distance. The male’s bands tell us quite a lot about his history and this nest. He first arrived in 2016. By identifying his green NJ band as D10, I was able to learn that he was banded as a nestling at another Sussex County nest in 2010. Although I didn’t see any battles, it was clear that he and the young (fourth year) female he arrived with were the new pair in town, replacing the eagle pair that we had been seeing for at least five years prior. I didn’t know where their nest was and spent a lot of time looking for it, but I still saw them frequently throughout their territory. I eventually learned their nest is in Wawayanda.

The female was not banded and therefore harder to track. I don’t know for sure, but I believe the original female from 2016 may have been replaced in 2020. That year, the Wawayanda nest failed– did not fledge any chicks – and a pair of eagles were seen building a new nest near the old one. That failure, the new nest, and their behavior during the 2021 nesting season are why I think a new female took over that year. I was able to see and confirm the male’s bands, so I knew he remained. But the eagles did something I hadn’t really seen in all my years of monitoring – when either eagle was flying into the nest, they would call out, almost as if they were saying, “Hey, it’s me, not a stranger.” They did that throughout the 2021 nesting season, but not in any subsequent season. It was as if they were learning about each other that year and once they really knew each other, never had to do it again.

This pair has been special to watch. To survive in a territory as large and challenging as landlocked northwestern New Jersey, the eagles must be especially resourceful because their nest-building, egg laying, and even early hatching season takes place when their primary food source (fish) may not be available. And they must be strong enough to repel intruding eagles across many miles to protect their dispersed food sources. When they had chicks in the nest, the male’s primary job was maintaining the security of their territory and providing food, while the female needed to ensure survival of their young. When the male was too involved with security matters, as happened in both 2023 and 2024, the female was hunting, feeding the chicks, and protecting the nest area on her own because the male was in another part of their territory for long stretches.
Between 2021 and 2024, this pair fledged eight eaglets. Watching them accomplish this with fine-tuned teamwork and a secure bond has been a real privilege.

When I retrieved the dead eagle and saw it was  not banded, I thought first of the fierce Wawayanda female. With the eagle found near her favorite perching spot and few visitors in the area, it seemed likely to be her. In the two weeks after the eagle was found, two weeks that are the heart of the Wawayanda eagles; mating, nesting and egg laying season, the male waited for her by the nest. I watched him for hours, hoping I was wrong, that she would return, and the season would go on as normal. But that didn’t happen and after all of this, I’m as sure as I can be that it was indeed her. Preliminary tests are positive for Highly Pathogenic Avian Influenza (HPAI, or bird flu), which is hitting birds in our state heavily this year.

She was strong and beautiful, and I’ll miss her quite a lot. I’m sure the male spent those few weeks also missing his bonded mate. But the eagles must focus on the future and by his nature he knows he needs a new mate. As he searches for his next partner, there is no guarantee that he will even remain at Wawayanda. He may choose to move on or he may lose control to other eagles who are looking for a nesting area. I do know that there are a lot of prime nesting spaces open in our area and I hope that whoever “loses” at Wawayanda moves down the road and settles in at a nearby spot.

What happened since the female’s body was found demonstrates both the fragility and the resiliency of bald eagles in New Jersey. I have great hope that the Wawayanda nest will continue successfully and look forward to the next chapter.

Two adorable fluffy chicks have hatched live on the Duke Farms Eagle Cam. There is a pip in the third egg, so the third chick should hatch very soon. Thanks to Duke Farms and staff who host, fund and maintain this cam. The cam is new for the 2025 season and now has audio which allows you to hear the chicks peeping and adults calling. The clarity of the new cam is top notch.

The New Jersey Annual Bald Eagle Project report has been published by NJDEP Fish & Wildlife’s Endangered and Nongame Species Program and The Conserve Wildlife Foundation of NJ.  The NJ bald eagle nesting population continues to increase.  Two hundred ninety-three nest sites were monitored, of which, a record 264 were documented to be active (with eggs) and 29 were territorial or “housekeeping” pairs. In total, there were 288 fledglings resulting in a productivity rate of 1.2 young per active nest.

Partnerships were crucial in the early days of ospreys being listed as endangered in New Jersey in the early 1970s. From public utility companies installing tall nest platforms on coastal saltmarshes to non-profit organizations purchasing land for preservation. Today, they are still the life blood of osprey conservation, fifty years later. One partnership that has been brewing, quite literally, over the past several months was a collaboration and beer from Twin Elephant Brewing Company. They had this small batch beer called: The Osprey and they wanted it to help make a difference for the namesake of the beer, so they decided to partner with Conserve Wildlife Foundation of NJ to support our osprey conservation efforts.

It’s a good time of year to see bald eagles in New Jersey.  Many of New Jersey’s resident pairs are back at their nests, getting them ready for the 2025 nesting season.  Though the majority of pairs won’t start incubating until February, there are always a few “early bird” pairs that start laying eggs in January.

In addition to the nesting pairs there are immature eagles (those that aren’t yet five years of age and sexually mature) and wintering eagles that come to New Jersey from areas where it’s much colder and the water has frozen.  A good spot to find eagles is around water supplies that aren’t frozen solid such as rivers and the Delaware Bay. Here are some photos taken by NJ Eagle Project volunteers in November and December of 2024.

There are two upcoming events where you can learn more from us about our efforts to monitor and conserve bald eagles in New Jersey, the NJ Meadowlands Eagle Festival (January 12) and the Cumberland County Winter Eagle Festival (February 1). Click on the links to learn more about these events.

Summer Re-sightings of Red Banded Ospreys

I never imagined the rewarding experience of observing adult ospreys that I banded as nestlings. Over the past decade, I have banded six hundred and twelve ospreys with field readable red auxiliary bands. These birds originated from nests throughout the Barnegat Bay watershed, from Point Pleasant to Little Egg Harbor. This year, 29 red banded ospreys were re-sighted along the coast of New Jersey.
