The 2025 nesting season for ospreys in New Jersey began as others. Breeding adults returned to their nests in March and April, pairs reunited, and nesting activity got underway on schedule. But as the season progressed, it became clear that this year would be anything but typical.
A nor’easter in late May marked a turning point. Lasting nearly three days, the storm brought strong winds, heavy rain, and coastal flooding. Conditions that made it extremely difficult for ospreys to find food. As observed in previous years, these types of storms are known to disrupt foraging in the ocean, and in many cases, lead to brood reduction or nest abandonment. However, weather alone does not explain what we observed.
Each spring, wildlife enthusiasts across New Jersey — and beyond — tune in to watch one of the state’s most exciting conservation success stories unfold in real time: the Union County Falcon Cam. This season, viewers witnessed an unusual change when the nesting female was replaced mid-season. What makes this especially remarkable is that the new female is now incubating the five eggs laid by the previous female.
As I finalize our annual report summarizing last year’s data, I often find myself looking back to reflect and compare trends over time. I’ve worked with ospreys long enough to have witnessed their population in New Jersey more than double. Their recovery has long been a clear sign of improving ecological health in our coastal waters.
Highly pathogenic avian influenza (HPAI) is circulating once again this winter and has already been confirmed in New Jersey in Canada geese, Snow geese, and Bald eagles. This virus primarily affects birds and can spread quickly among species that congregate in large numbers or come into close contact with one another.
Waterfowl and raptors — especially scavengers like bald eagles — are particularly vulnerable. Eagles are often exposed when feeding on infected waterfowl or carcasses, which increases the risk of illness and mortality. Monitoring and reporting cases is critical for tracking the spread of the disease and protecting both wildlife and domestic animals.
Members of the public are urged to report sick or dead birds, especially waterfowl and raptors.
Sick or dead bald eagles should be reported immediately to the NJDEP at 1-877-WARN-DEP (1-877-927-6337).
Please remember that precautions should always be taken when encountering sick or dead birds, particularly during the winter months. Avoid direct contact whenever possible. If handling is unavoidable, wear a face mask and disposable gloves, and be sure to disinfect boots and equipment afterward.
Staying informed and reporting observations helps wildlife agencies respond effectively and protects New Jersey’s birds during this ongoing outbreak. For more information, visit the NJ Department of Agriculture’s HPAI page.
We’re thrilled to see the fourth and final peregrine falcon egg hatch atop the Union County Courthouse in Elizabeth via the Union County Falcon Cam. The nest is now bustling with activity as proud parents Frida and Mango care for their four fluffy eyases.
The first three chicks, now nearly a week old, are growing rapidly—peregrine falcon chicks can double their weight within just six days of hatching. The newest hatchling, only a day old, is already being attentively brooded and fed by the adult. At this early stage, the chicks are covered in soft white down and rely entirely on their parents for warmth and nourishment.
Over the coming weeks, these eyases will continue to grow quickly, developing juvenile feathers and strengthening their muscles in preparation for fledging. Typically, peregrine falcons fledge around 6 to 7 weeks of age, so we can expect these chicks to take their first flights in early to mid-June.
Stay tuned to the Union County Falcon Cam to witness these remarkable developments in real-time. It’s a fascinating glimpse into the life cycle of one of nature’s most formidable aerial predators!
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.
Three natural osprey nests within Sedge Island WMA. July 2024.
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.
