Exciting news for osprey watchers—Duke has returned! This morning, the longtime male of our Barnegat Light Osprey Cam returned to his home on Long Beach Island after an incredible journey south for the winter. After months of migration, crossing thousands of miles between New Jersey and the tropics, Duke is back to reclaim his territory. But this year, there’s a twist—a new female is waiting for him!
His previous mate, Daisy, has not yet been spotted, and while we don’t know much about this new female (since she’s unbanded), we’ll be closely observing her iris and feather patterns to track her identity. Today, Duke wasted no time settling in—he was seen feeding on his perch, interacting with the newcomer, and lounging in the nest bowl (classic Duke). If Daisy doesn’t return, he will likely form a new pair bond with this female, marking a fresh chapter in his long and successful life.
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!
Seeing Red | Engaging Future Generations in Osprey Conservation
Ospreys have made a resounding recovery throughout New Jersey, where over 800 pairs nest along the majority of our waterways. NJDEP upgraded their status from threatened to stable in early 2025. Today, citizen scientists play a crucial role in monitoring ospreys and the health of their population throughout the state.
During this talk, Ben Wurst, Senior Wildlife Biologist with Conserve Wildlife Foundation of NJ will talk about efforts to monitor and manage ospreys over the past two decades with emphasis on engaging the public in reporting nest activity online, through Osprey-watch.org.He will also discuss Project RedBand, an osprey banding and re-sighting project that was founded on Long Beach Island and how the public can help contribute to their long term stability.
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.
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.

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.

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..
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.
