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!

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.

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.

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.

‘Tis the season for osprey nest platform repairs — and being thankful for the volunteers who make it happen!

After migratory birds depart, leaves fall and northwest winds prevail, a small group of dedicated volunteers descend on our coastal saltmarshes. They’re there to maintain osprey nest platforms. Around 75% of our nesting ospreys rely on these wooden structures to reproduce. They were used to help jumpstart the early recovery efforts of ospreys in coastal New Jersey, where much of their native habitat was lost to development in the 1950-60s. Today many of these platforms are reaching their life span or are very close.

CWF Biologist Todd Pover and the Barnegat Light Habitat Restoration Project are back in the news with a wonderful write-up by Juliet Kaszas-Hoch on TheSandpaper.net.

With major construction wrapping in late-2019, we’re now seeing the project’s positive impact on the local piping plover population. Only time will tell just how successful the restoration truly is, but until then we will continue to chart it’s progress and do what we can to make life better for New Jersey’s beach nesters.

Read an except of article here and remember to check out the video update on the project linked below!

With fall on its way, most piping plovers and other migratory coastal birds have headed south, where they will remain for the duration of the winter months. While they’re gone, other species will happily utilize the new pond feature and habitat site along the inlet in Barnegat Lighthouse State Park created specifically to benefit beach-nesting birds such as plovers.

The Barnegat Light Habitat Restoration Project is a collaborative effort led by Todd Pover, Conserve Wildlife Foundation of New Jersey senior wildlife biologist, and Brooke Maslo, Rutgers University assistant professor of ecology, in partnership with the U.S. Fish and Wildlife Service, the U.S. Army Corps of Engineers and the N.J. Division of Fish and Wildlife.

As Pover explained in a recent blog post on conservewildlifenj.org, the goal of the project, begun two years ago, was to enhance breeding habitat near Long Beach Island’s north-end inlet “by clearing out the vegetation and re-grading the sand, because this once important breeding site had become overgrown and was no longer suitable for piping plovers to nest. Plans also called for building a shallow pond to create productive foraging habitat for chicks (to) be protected from human disturbance.”

Today is designated World Shorebirds Day!

Here at The Conserve Wildlife Foundation of New Jersey we are proud of our ongoing conservation efforts with piping plovers and red knots, both imperiled shorebirds. Along with our partners, we are doing our best to keep these species in our future, but our work is not done, as shorebird species all around the world are in steep decline. Habitat across the range, critical for their survival, is under siege from development, commercial uses, and human recreational activity.

Click on the link below to hear what CWF Senior Wildlife Biologist Todd Pover had to say about piping plovers, their success this past season in New Jersey and challenges over the decades, as part of a series of interviews compiled for World Shorebird Day!

Grounded: Resurgence of natural osprey nests

by Ben Wurst, Habitat Program Manager

It’s not very common to see ospreys, a large predatory bird, nest on the ground. Despite the rarity of these sightings, it has become more common and acts as a glimpse into the past (and future), before humans dominated the landscape. Today, more and more ospreys are building nests on the ground and snags over water.

Results from 2019 Osprey Nest Surveys highlight another productive year.

by Ben Wurst, Habitat Program Manager

Surveys of osprey nests in New Jersey have occurred annually for the past forty five years. They are conducted to help determine the overall size and health of the population. The first aerial survey over Barnegat Bay counted only five active nests. Ten years earlier there had been over 50. The combined effects of DDT and habitat loss had taken their toll. No osprey nests were productive and the population at risk of being extirpated from the state.

“In 1974 there were only five active osprey nests on Barnegat Bay. Today there are approximately one hundred and fifty.”

After ospreys were listed as endangered an innovative effort to transplant viable eggs from the Chesapeake Bay to Barnegat Bay began. In addition, to help replace natural nest sites that were lost to development, man-made nest platforms were designed and installed away from human disturbance. Slowly osprey pairs became productive thanks to the die hard effort of State biologists like Pete McLain, Kathy Clark and many volunteers and partners. It’s encouraging for us to look back to see how far we’ve come in the statewide recovery of ospreys in New Jersey.
