Ospreys are migrating north and will soon begin another nesting season in New Jersey. Earlier this year, their conservation status was upgraded from threatened to stable by NJDEP. This marks a tremendous success in the restoration of ospreys, management of their nesting structures, and vast improvements in the health of our aquatic ecosystems, and the efforts of many devoted environmental professionals and osprey lovers throughout the state. Results from 2024, show that ospreys had favorable conditions for their continued growth and success.
To track the health of the osprey population, each year project staff, volunteers, and citizen scientists collect data on nest occupancy and nest success. Most colonies are surveyed by devoted volunteers who use a ladder to access a nest and determine the outcome. Others are surveyed from a distance using optics or other visual aides, including digital cameras and unmanned aerial systems. Citizen scientists, who contribute observations of nest activity online through www.osprey-watch.org play a crucial role in determining the overall size and health of the state population, as many document nest success in areas where previous nest surveys were not conducted. Moving forward, theses passionate volunteers will play a more important role in monitoring ospreys and their continued success.

Overall, results from our surveys recorded a total of 729 nests that were occupied. The majority of nests monitored had increased productivity, which is a stark contrast from what was observed in 2022 and 2023, when most colonies had decreased productivity. This highlights how severe weather, specifically nor’easters, can affect the overall productivity of coastal nesting ospreys, where most osprey nests are located in New Jersey. With no severe weather, the average statewide productivity was normal at 1.63 young/active [known outcome] nest.
As reported last year, observations of adult females not laying eggs at prompted us to conduct some early season surveys in some colonies. A survey that we conducted on Barnegat Bay revealed that 40% of the nests surveys had no eggs or young, which normally had young in previous years. Similar findings were reported in the Great Egg Harbor colony and also in areas of the Chesapeake Bay, which is even more alarming. We still don’t know what caused the reduction in egg-laying females and delayed incubation. More investigation and future monitoring is warranted.
In general, ospreys had a productive season, with the outcome being determined in 73% of the nests surveyed in 2024. Those pairs (533) produced a total of 867 young. A total of 101 (12%) nestlings were banded for future tracking, 35 of which with both federal and red auxiliary, field readable bands at nests on Barnegat Bay. 89 nests were determined to have failed to produce young. This means they either had eggs or nestlings and they were lost.

Osprey Band Recoveries
Each year a small portion of young ospreys are banded with federal bird bands for future tracking. Encounters with banded birds is infrequent, unless they are found injured or dead, mainly because the bands are very difficult to read on live birds. With Project RedBand, an osprey banding and re-sighting project on Barnegat Bay, we have seen more encounters with live ospreys than those that are injured/dead. This is a direct result of banding birds with red “field readable” auxiliary bands, which can be read from a distance using a spotting scope or a telephoto lens on a digital camera. In 2024, 41 ospreys that were banded as nestlings were encountered. Of those, 30 were identified by their red bands, most during nest surveys conducted by CWF staff. Obtaining re-sightings of red banded ospreys helps track individual birds as they return to New Jersey to nest as adults. We can learn a lot about their life history while engaging the public in osprey conservation. Thank you to everyone who has reported red banded ospreys that they have observed!
With ospreys being listed as stable, it means they’re not at risk of becoming threatened or endangered in the near future. It does not mean we should just forget about them or walk away. Our continued efforts to monitor ospreys will help track their health and any impacts from threats like plastic marine debris to the loss of vital prey, like menhaden shifting northward from the effects of climate change. We have to continue to maintain their nest structures, which the majority of ospreys rely on to successfully reproduce.
Thankfully we have a growing group of volunteer “osprey watchers” who will help keep tabs on them in the future. As one of the largest birds of prey that nests in very close proximity to humans, especially on our heavily developed coast, creating a connection between ospreys and people is resilience. The ability to adapt to a changing landscape is crucial to our shared prosperity in this region. We must protect our open space and habitats that wildlife depend on to survival, while also allowing our human way of life to move forward.
Special thanks to everyone who donates to support our work with ospreys and to all our volunteers who help maintain their nest structures and monitor nest activity throughout the state!

Wawayanda Pair, photo by Christine Alber
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.
Banding and re-sighting birds is such a rewarding experience. You never know where and when a bird that you banded will show up and what you will learn from that encounter. Banding is a method for biologists to track migratory birds and gain valuable information about them through band re-sightings or encounters. Each year, around 10-20% of young ospreys that are documented during nest surveys in New Jersey are banded with USGS bird bands for future tracking. On Barnegat Bay, through Project RedBand, young ospreys are also banded with red auxiliary, or “field readable” bands. Since 2014, over 600 red bands have been deployed and in recent years we have had more re-sightings of birds that are alive as opposed to those that were found dead. In 2024, we identified 30 ospreys in New Jersey by their red bands.
In late 2024 we closed out our third year of comprehensive monitoring and management of nesting and migratory birds at Horseshoe Island. The recently formed island, situated just outside the southern edge of Little Egg Inlet, has quickly become one of the most important beach nesting bird sites in New Jersey.
Each year has presented new challenges and changes on the island and in 2024 there were a number of “firsts” to report. Piping plovers had previously utilized the island to rest and forage during both the migration and breeding seasons, this was the first year that they nested there. Adding any new nesting site for piping plovers in New Jersey is big news, adding three pairs was even more exciting. Although all three pairs hatched young, no chicks successfully fledged from the island, but we hope to build on that initial success next year.
Horseshoe Island is home to the northernmost royal tern colony in the hemisphere and the colony has grown in size each year. In 2024, CWF joined New Jersey Fish and Wildlife (NJFW) and The Wetlands Institute (TWI) to band royal tern chicks, the first time that royal terns have been banded in the state. With their newly minted blue field readable bands, we are now able to track movements and longevity of “our royals.” Under NJFW’s direction, adult piping plovers were also banded at Horseshoe for the first time this year. Lastly, led by TWI, black skimmer chicks were once again banded on the island.

The island grew exponentially this year, it is now at least twice the size it was when monitoring began in 2021. The birds took advantage of the expanded habitat, upwards of 1400 state endangered black skimmers nested there in 2024, easily making it the largest skimmer colony in the state. And nearly 600 skimmer chicks fledged from the site, making it the most successful year to date for skimmers on Horseshoe Island. Large least and common tern colonies were also present. And American oystercatchers have increased from 6 to 16 breeding pairs since 2021; 2024 being the most productive year yet with 24 fledglings being recorded. Nearly every part of the island was in use, even more so if you factor in migratory and staging shorebirds that often crowd the tidal zones on the outer edges of the island and the interior lagoons for foraging.

Monitoring and management of the island is done as a partnership between CWF, NJFW, and Edwin B. Forsythe National Wildlife Refuge. For more information about the island, read the recently released 2024 report.

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.
This marked my second year attending the Northeast Bat Working Group’s (NEBWG) annual meeting, a highly regarded 3-day event that convenes researchers, biologists, and educators to address the challenges bats face across North America. As in previous years, the meeting proved to be both inspiring and thought-provoking.
Discussions centered on the primary threats to bat populations, including white-nose syndrome, habitat loss, climate change, and collisions with infrastructure such as wind turbines. Attendees presented their research, proposed innovative solutions, and collaborated on strategies to mitigate these pressing issues. Sessions covered a diverse array of topics, from advancements in bat rehabilitation techniques to improved methods for monitoring populations and assessing the impacts of climate change.
In a landmark decision, the bald eagle and osprey have been removed from New Jersey’s endangered species list. This remarkable achievement is the result of decades of dedicated conservation efforts and collaboration between government agencies, environmental organizations like Conserve Wildlife Foundation, and the public. The recovery of these iconic birds demonstrates the power of focused conservation initiatives and habitat protection.
The bald eagle, once on the brink of extinction due to DDT use and habitat loss, has made an incredible comeback in New Jersey. From a single nesting pair in the 1970s, the state now boasts 293 nesting pairs. Similarly, ospreys have rebounded from just 50 nests in the 1970s to more than 800 today.
These success stories highlight the effectiveness of long-term conservation strategies, including habitat restoration, nest protection, and public education. They serve as inspiration for future conservation efforts and remind us of the positive impact we can have when we work together to protect our natural heritage.
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.
