I monitor a bald eagle nest located in Wawayanda State Park, Sussex County. My heart sank when I was asked to retrieve the carcass of a bald eagle found dead on nearby Highland Lake. The Wawayanda eagles protect a large and rugged territory that includes many smaller ponds, several swamps and other wetlands, and seven lakes, including those in my community. I feared that the dead eagle was one of the Wawayanda pair. Despite their territory’s size, our local eagles are in some ways easy to follow. When the lakes are frozen, as they are this winter, we see few visiting eagles traveling through. Although eagles appear similar, each eagle is really an individual in look and behavior. After watching them closely for years, I’ve learned a lot about the eagles; characteristics, their habits, and their favorite places to perch. Moreover, the male is banded and wears distinctive green and silver ankle bands, which stand out even from a distance, especially with a pair of binoculars.

Bald eagles banded in New Jersey receive two separate bands – a silver band from the federal US Fish and Wildlife Service with a unique six-digit ID number and a state green band with a two-digit code etched in silver. Because of its color and the shorter code, the state band can be read from a distance. The male’s bands tell us quite a lot about his history and this nest. He first arrived in 2016. By identifying his green NJ band as D10, I was able to learn that he was banded as a nestling at another Sussex County nest in 2010. Although I didn’t see any battles, it was clear that he and the young (fourth year) female he arrived with were the new pair in town, replacing the eagle pair that we had been seeing for at least five years prior. I didn’t know where their nest was and spent a lot of time looking for it, but I still saw them frequently throughout their territory. I eventually learned their nest is in Wawayanda.

The female was not banded and therefore harder to track. I don’t know for sure, but I believe the original female from 2016 may have been replaced in 2020. That year, the Wawayanda nest failed– did not fledge any chicks – and a pair of eagles were seen building a new nest near the old one. That failure, the new nest, and their behavior during the 2021 nesting season are why I think a new female took over that year. I was able to see and confirm the male’s bands, so I knew he remained. But the eagles did something I hadn’t really seen in all my years of monitoring – when either eagle was flying into the nest, they would call out, almost as if they were saying, “Hey, it’s me, not a stranger.” They did that throughout the 2021 nesting season, but not in any subsequent season. It was as if they were learning about each other that year and once they really knew each other, never had to do it again.

This pair has been special to watch. To survive in a territory as large and challenging as landlocked northwestern New Jersey, the eagles must be especially resourceful because their nest-building, egg laying, and even early hatching season takes place when their primary food source (fish) may not be available. And they must be strong enough to repel intruding eagles across many miles to protect their dispersed food sources. When they had chicks in the nest, the male’s primary job was maintaining the security of their territory and providing food, while the female needed to ensure survival of their young. When the male was too involved with security matters, as happened in both 2023 and 2024, the female was hunting, feeding the chicks, and protecting the nest area on her own because the male was in another part of their territory for long stretches.
Between 2021 and 2024, this pair fledged eight eaglets. Watching them accomplish this with fine-tuned teamwork and a secure bond has been a real privilege.

When I retrieved the dead eagle and saw it was  not banded, I thought first of the fierce Wawayanda female. With the eagle found near her favorite perching spot and few visitors in the area, it seemed likely to be her. In the two weeks after the eagle was found, two weeks that are the heart of the Wawayanda eagles; mating, nesting and egg laying season, the male waited for her by the nest. I watched him for hours, hoping I was wrong, that she would return, and the season would go on as normal. But that didn’t happen and after all of this, I’m as sure as I can be that it was indeed her. Preliminary tests are positive for Highly Pathogenic Avian Influenza (HPAI, or bird flu), which is hitting birds in our state heavily this year.

She was strong and beautiful, and I’ll miss her quite a lot. I’m sure the male spent those few weeks also missing his bonded mate. But the eagles must focus on the future and by his nature he knows he needs a new mate. As he searches for his next partner, there is no guarantee that he will even remain at Wawayanda. He may choose to move on or he may lose control to other eagles who are looking for a nesting area. I do know that there are a lot of prime nesting spaces open in our area and I hope that whoever “loses” at Wawayanda moves down the road and settles in at a nearby spot.

What happened since the female’s body was found demonstrates both the fragility and the resiliency of bald eagles in New Jersey. I have great hope that the Wawayanda nest will continue successfully and look forward to the next chapter.

Harrison is thrilled to join the CWF team as the newest staff biologist and contribute to the plethora of wildlife work being done, including wildlife monitoring at Joint Base McGuire-Dix-Lakehurst in partnership with United States Fish and Wildlife Service New Jersey Field Office, bird surveys, rare turtle research, and other wildlife projects.

A lifelong resident of South Jersey, Harrison has always been drawn to the coast and the natural wonders of the area, inspiring him to eventually pursue a bachelor’s degree in Marine Biology from the University of Rhode Island. There he became a certified rescue and scientific diver, studying coral reefs firsthand in Bermuda. However, his career path unexpectedly shifted to wildlife biology after taking a field ornithology class, where his excitement and passion for birds and wildlife biology bloomed. 

After graduating, Harrison pursued a variety of bird related seasonal work, starting as an intern at the Wetlands Institute, being involved in their coastal bird research program and conducting his own project investigating nest success and parameters of Saltmarsh and Seaside Sparrows. From there he worked as a Research Technician for Cellular Tracking Technologies, a wildlife telemetry company, and as a spring migration counter for the Cape May Bird Observatory. Harrison hit the road to Idaho afterwards to survey a threatened population of Yellow-billed Cuckoo as well as migratory shorebirds before joining CWF the next field season as a technician on the Delaware Bay American Oystercatcher Project. 

A self proclaimed “bird nerd,” Harrison spends time outside of work birding and learning more about the world of birds. When he’s not in the field, Harrison enjoys getting in the water to surf, SCUBA, swim, or take a leisurely paddle. On more relaxed days he enjoys going to gym, cooking tasty food, and hunting for great restaurants and breweries. 

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.

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.

Earlier this month, the New Jersey Department of Environmental Protection (NJDEP) announced significant changes to the state’s Endangered and Threatened Species List. These updates reflect both encouraging conservation successes and ongoing challenges for our state’s diverse wildlife.

A Conservation Milestone

In a landmark decision, the bald eagle and osprey have been removed from New Jersey’s endangered species list. This remarkable achievement is the result of decades of dedicated conservation efforts and collaboration between government agencies, environmental organizations like Conserve Wildlife Foundation, and the public. The recovery of these iconic birds demonstrates the power of focused conservation initiatives and habitat protection.

The bald eagle, once on the brink of extinction due to DDT use and habitat loss, has made an incredible comeback in New Jersey. From a single nesting pair in the 1970s, the state now boasts 293 nesting pairs. Similarly, ospreys have rebounded from just 50 nests in the 1970s to more than 800 today.

These success stories highlight the effectiveness of long-term conservation strategies, including habitat restoration, nest protection, and public education. They serve as inspiration for future conservation efforts and remind us of the positive impact we can have when we work together to protect our natural heritage.
