Just yesterday, as February comes to a close, I saw my first pair of American oystercatchers on breeding territory on Long Beach Island. The first piping plover of the season will likely be sighted in New Jersey sometime next week or so. Still, as we remain in the midst of one of the harshest and snowiest winters in a long time here on the New Jersey coast, it’s hard to believe that CWF staff will be back out at Horseshoe Island in just over a month to start biological monitoring for the 2026 beach nesting bird season.
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.

During our osprey nest surveys we are always looking for auxiliary banded birds. Last summer over 40 red banded ospreys were re-sighted, which is the most ever encountered in a single year. The majority were breeding birds, photographed on their nests and others were photographed in flight or perched, often with prey. Some were even re-sighted several times throughout the year.
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.

Over the past twenty years, I’ve had the privilege of watching New Jersey’s osprey population more than double—from roughly 400 nesting pairs to over 800. While our work to protect and expand nesting habitat has played a role in their comeback, the true foundation of their recovery has been a healthy marine ecosystem and an abundance of prey.
Since 2006, the Women & Wildlife Awards have honored powerful voices in conservation—from scientists and educators to policy advocates—who have helped restore bald eagles, brook trout, golden-winged warblers, and more across New Jersey. These leaders have preserved thousands of acres, launched statewide education initiatives, and inspired countless others to act.

Since my last post on June 25, where I said this year was shaping up to be a “terrible one” for ospreys in New Jersey has held true. Since then I’ve watched as nestlings are abandoned and left to starve by their parents and die from starvation via live streaming cameras. It is heartbreaking. We’re seeing nest failure rates higher than they have ever been in most coastal colonies. Even worse, many others monitoring ospreys in surrounding states are reporting similar outcomes. Atlantic menhaden—typically a staple in the osprey’s diet—are far less abundant this season.

Northern diamondback terrapin nesting season may be coming to end, but Conserve Wildlife Foundation’s Great Bay Terrapin Project volunteers are still hard at work. During the peak of their nesting season, in June and July, they drive up and down Great Bay Boulevard in Little Egg Harbor Township in search of terrapins crossing the road.
Summertime is peak terrapin crossing season, with females coming to shore to lay their eggs in early to mid-summer and hatchlings finding their way back home in August. The problem is, they often end up on the road, where they run the risk of being crushed by passing vehicles. On Great Bay Boulevard, a coastal road with few speed limit signs and a great number of terrapins, this is especially troublesome.

This year is shaping up to be a terrible one for ospreys in New Jersey. Early season surveys, which we began to conduct more of in recent years, after nor’easters and shortages of prey caused nesting pairs fail to produce young. These early surveys provide valuable data on the outcomes of nests and insight on nest failures.
This spring and early summer, we have observed a high number of nest failures in an area around Long Beach Island on Barnegat Bay. This has also been observed directly through live streaming osprey cams from Cape May to Oceanville and reported by some of our dedicated volunteers in other areas. Right now all signs point to lack of food, which either caused adults to abandon incubation or starvation of their young.
A crucial prey item for ospreys is Atlantic menhaden, a forage fish that is found in the ocean and estuaries. They are found all along the Atlantic coast and are widely considered to be the most important fish in the sea. Not only are they filter feeders but they are food for a very wide variety of wildlife, from humpback whales and dolphins to ospreys, loons, tuna and striped bass, etc. They are also a very valuable fish that is used as whole bait, meal (solids, mainly for use in aquaculture as food for farm raised fish) and oils. In 2016, over 323 million pounds of menhaden was landed in Virginia alone. In coastal Virginia, osprey populations have collapsed and the likely culprit is lack of prey.
This spring adult menhaden were not very plentiful, especially after a nor’easter impacted the coast in late May. Observations of ospreys showed some were still catching menhaden but much smaller fish. Since then it has been a cascading effect of adult male ospreys not being able to find enough food to feed their mates and their young. When they can’t find food, they spend more time and energy searching and hunting and less time at their nests, leaving their mates to do more incubation and often times starving. This is when incubating females have to leave their nests and then their eggs or young are exposed to predators or harsh environmental conditions like extreme heat, which results in nest failure. There are still plenty of fish available to ospreys but fewer adult menhaden, which ospreys are more dependent upon, especially during this time of year when they are foraging more frequently to provide for their families. As a bioindicator species, ospreys showing us the shortage of menhaden in real time through the lens of their failed reproduction.
We hope learn the full extent of food stress on ospreys this year during upcoming nest surveys. For those who watch a nest or have a pair that nest near your home, you are encouraged to report osprey nesting activity online, via Osprey Watch. Since ospreys were recently upgraded to stable as their conservation status, we are concerned about their long term stability in a rapidly changing world. Your support to help us monitor ospreys during this time is crucial, as we do not receive any state or federal funding to carry out this important fieldwork.
