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.
Peregrine falcons, once on the brink of extinction in the eastern U.S., have made a remarkable comeback thanks to conservation efforts throughout the region. Urban nesting sites like the Union County Courthouse provide a safe haven for these raptors, offering protection from human disturbance and plentiful food sources. Over the next several weeks, the dedicated parents will take turns keeping the eggs warm until they hatch, bringing new life to downtown Elizabeth.
As we welcome spring’s renewal, we also celebrate the resilience of these magnificent birds. Join us in watching their life cycle unfold via the Union County Falcon Cam. We are thankful to continue our partnership with Union County to help stream this live view and share their incredible life history with the world.

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!

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.
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.
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.
