Three young osprey chicks found themselves without their parents after a utility pole nest caught fire at the National Guard Training Center (NGTC) in Sea Girt, NJ. Osprey often choose utility poles as nesting structures because of the 360° view they offer. Fires caused by the nests, composed mostly of dried sticks and seagrass, aren’t uncommon. Because of the safety hazard imposed by the nest, it was removed from the utility pole at the NGTC with three healthy chicks inside. The chicks were approximately a week to ten days old when removed from the nest and were brought temporarily to The Raptor Trust in Millington by Charles Appleby, Chief of the Environmental Bureau of the NJ Department of Military and Veterans Affairs (NJDMAVA) to be cared for while a new nesting platform could be built. Reuniting the chicks with their parents in a safe nest box would give them their best chance at survival.

Depending on where you look and who you talk to, the fate of many osprey nests might bring tears to your eyes. Since a nor’easter impacted the coast with strong onshore winds for several days, young ospreys have been dying of starvation in plain sight. Over the past week, several reports of adults who abandoned their nests with young have been received. This year, weather has impacted the availability of fish and outcomes of nests in the Garden State.
We’re proud to release results of the 2022 New Jersey Osprey Project Survey, which documented the greatest number of nesting ospreys in the history of the project. Overall, surveys by staff and loyal volunteers recorded a total of 733 occupied nests throughout the state. The majority of ospreys (83%) continue to nest along the Atlantic coast of New Jersey with the remainder nesting along the Delaware Bay and inland locations. Surveys recorded the outcome of 73% of the known population, which allows us to present these results with confidence.

I have been finalizing osprey band re-sightings and encounters from last year and one particular band number stood out. It was 98/K, who was re-sighted by Bob Peal during his visit to Barnegat Lighthouse State Park on May 17, 2022. There he photographed a variety of wildlife, including several ospreys who had red auxiliary bands, one of which was readable!

In 2014, we began to band osprey nestlings produced at nests within the Barnegat Bay watershed with auxiliary bands. This was an effort which came about from the interest of Jim Verhagen, a LBI resident and wildlife biographer. He wondered why young ospreys were not banded with color, field readable bands, like some endangered raptors, including bald eagles and peregrine falcons. This spawned Project RedBand, an osprey banding and re-sighting project. The goal of the project was to learn more about ospreys when they are alive while engaging coastal residents in their management. Just under 500 young ospreys were banded with red auxiliary bands from 2014-2020 from nests all along the Barnegat Bay estuary.

Whenever we look at how ospreys are faring, weather is always taken into account. When we summarize and report on the results of our summer osprey nesting surveys, we also look at the local climate. Being situated along the Atlantic coast, our weather is influenced by the ocean. As aerial predators of fish, ospreys are reliant on favorable water conditions to forage.
Preliminary results of the 2022 New Jersey Osprey Project Census show that the osprey population was not as productive this year as they have been over the past ~20 years. This was largely due to a low pressure system (nor’easter) that stalled off the coast in early May — when the majority of pairs were incubating eggs. The strong onshore winds caused moderate coastal flooding, windy conditions, increased wave action and water turbidity, which made it more difficult for ospreys to find and catch prey in coastal waters. Males do 100% of the foraging from the onset of egg laying until young begin to fledge, so when they are unable to provide food, females must abandon their nests and eggs to forage for themselves. The nor’easter in May appears to have affected the outcome of many coastal nests and in some cases, complete colonies. Of course there are many other causes for nest failure but this year weather played a major role.

In the coming weeks CWF staff, NJDEP Biologists, and a handful of dedicated volunteers will descend onto the coastal saltmarshes of New Jersey to conduct a census of nesting ospreys. The last census was conducted in 2017 when 668 nesting pairs was recorded. They will survey remote areas of back bays by boat. Nests are surveyed in a variety of methods, with ladders being the traditional method, which allow for closer inspection of nests and banding of young for future tracking. Other nests are surveyed from a distance using optics or cameras with telephoto lenses, a mirror, smartphone or GoPro on an extension pole and a sUAS (when operated by a FAA licensed unmanned pilot). The goal is to recorded the total number of nesting pairs throughout the State.
A season of change and hope at the Barnegat Light Osprey Cam.

By far, this was the most viewed season of the Barnegat Light Osprey Cam, with over 360,000 views and 111,000 hours watched! It was a season of change. Viewers throughout the world watched as the mated pair successfully fledged two healthy young. We witnessed the trials and tribulations of a new pair, especially the female, who we believe attempted reproduction for the first time in her life. We saw that life as a young osprey was not always guaranteed, which is something we rarely get to witness but know is quite common at many nests throughout the world; however, with an experienced male and plentiful prey, the surviving young thrived. As we work on a season long highlight video, here is a brief summary of their nesting season.
A couple weeks ago colleagues with NJ Fish & Wildlife shared a video clip of a dark osprey who landed on a nest platform along the Maurice River near Leesburg, NJ. “Looks like an oiled bird” the text read. Indeed it looked like the bird was exposed to some form of petroleum product, which stained its feathers a dark color. At the time, there was no oil spill reported to NJDEP (this was on May 10) and the video shows that the bird was observed on the nest on May 1, 2021.
