The Three Bridges eagle cam went live for the 2024 nesting season on December 1st. A pair of eagles made an appearance that morning. The Three Bridges nesting platform was used by eagles in 2021, when they successfully raised two young. During the 2022 and 2023 nesting seasons, the pair were seen at the nest platform but ended up using a nest in a tree. We will see if the pair decides to use the nest platform this season. For now we believe that the Three Bridges pairs territory is both the nest tree and platform. As the numbers of nesting Bald Eagles continues to increase New Jersey there is the possibility that a second eagle pair could nest at the platform. Last nesting season there was lots of eagle action at the tower, eagles of all ages stopped by along with many different avian species. A pair of Osprey’s took interest in the nest platform but didn’t end up laying eggs. An American Kestrel perched at the platform on the first day the cam was live. It’ll be interesting to see what activity occurs at the tower this season.
The Duke Farms eagle cam is extremely popular and just this week viewers watched as two chicks hatched. These two chicks will be watched by a multitude of viewers over the next few months as they grow to become juveniles and leave the nest. As with anything in Nature, this pair has had it’s ups and downs. I wanted to summarize the history of this pair and nest. The male is a NJ banded bird (A/59) and has been in the pair from the beginning, he is 23 years old. Interestingly, there have been several females in the pair over the years. Thank you to Duke Farms for hosting the cam and their tech team that keeps it running smoothly when issues arise. The cam location has changed as well as the cam itself over the years and the quality of the picture has improved.
New Jersey’s eagle chicks were all fledged by the end of July, 2022. It was a successful nesting season for NJ’s eagles with 335 young eagles fledged. The results of the season will be available in December when the annual eagle report is published.
NJ Eagle Project nest monitors have reported that some eagles were seen working on their nests in September. NJ’s pairs don’t migrate and stay in NJ outside of the nesting season though they aren’t as tied to the nest. Each pair is different in when they will start returning and working on their nests for the 2023 season. One pair that is watched by thousands of viewers, is the Duke Farms eagle pair. The pair has been making appearances at the nest, though there are periods where they are not seen at the nest which is normal for this time of year. Nest monitor Diane Cook got this screen shot of both adults at the nest on Tuesday November 8th.
Diane reported the pair spent the night at the nest before flying off in the morning.
In 2022 the female at Duke Farm’s laid the first egg on January 17th, so we’re still over two months away from possible incubation. The majority of NJ’s eagle pairs won’t lay eggs until February.
As I write this there are two fluffy little chicks in the Duke Farms nest. They will have an audience of millions of eagle cam viewers watching them as they grow and fledge. As the adult eagles step around the nest, look closely and you will notice that one of them is banded. The male is A/59 and he is twenty-two years old. Twenty-two years ago I began my career with the Conserve Wildlife Foundation working with the New Jersey Eagle Project. In March 2000, A/59 hatched in a nest located in Greenwich, Cumberland County. When he was two weeks of age, he was fostered into a nest along the Rancocas River in Burlington County. The Rancocas pair had failed to produce their own young for a few years and fostering a healthy chick into the nest would help to keep the pairs fidelity to the nest site.
On May 15, 2000, he was banded and a radio transmitter was attached with a harness which was designed to eventually fall off. A/59 fledged on June 3 and was tracked until the transmitter’s signal was last recorded on October 22. You can read more details about the telemetry in the 2000 Bald Eagle Report.
In 2000, when he hatched and I started working with eagles there were 25 nesting pairs of eagles that fledged 29 young. Compare that to last year’s numbers of 247 pairs we monitored and 296 young fledged. As the number of eagles increases in New Jersey so does the competition for nest sites. A/59 has been able to defend and hold onto his territory at Duke Farms since 2009.
It’s very interesting to know the history of this eagle. I feel a bond with him since we both started our “eagle” journey at the same time.
It looks like the Duke Farm’s nest will only have two chicks this season.
One egg remains in the nest bowl and is still being incubated, but based on when the second chick hatched, March 1st, it should have hatched by now. We won’t know for certain why the egg didn’t hatch, but one theory is that it was the first egg laid.
There had been intruder eagles at the nest and fights between the adults and intruders. At one point both adults were off the nest for 20 minutes while an immature was in the nest. Perhaps something happened to the egg during these incidents.
The egg will eventually get buried in the nest or shoved to the side. The adults are busy bringing food to the nest for feedings and both chicks are getting plenty of food.
As a volunteer nest observer working for New Jersey’s Bald Eagle Project under the guidance of Kathy Clark and Larissa Smith, I watch and report on six nests in central and northern NJ. When the Duke Farms eagle cam first went online in 2008, I loved watching the adult pair and their nestlings whenever I was at home on my computer! Web cams give us an intimate look into the lives of eagles. By observing close up, so much can be learned about eagle behavior, and this nest was only five miles from my home in Hillsborough. These were my eagle neighbors! In May of 2019, during the annual banding of the two eaglets at the Duke Farms nest, the younger male (banded E/88), was outfitted with a satellite transmitter and became part of the research program “Eagle Trax” to discover where fledglings go when they leave the nest.
Duke first went online Sept 17, 2019, after he had left the nest area, beginning his journey to adulthood as an independent eagle. Although Duke has made short trips over to PA and even a couple times returned briefly to NJ, to his natal nest area, he spent most of his time in Maryland on the lower Susquehanna River and upper Chesapeake Bay.
“Duke” 11/24/20 @ Barb McKee
Then, early last November, I got an email from Kathy Clark. Duke had once again returned to NJ and was in Hillsborough, very close to our home on the Millstone River. I hustled right out with my scope and camera to see if I could spot him. If I was ever going to see Duke “in the wild” it would be now, with no foliage to block the views, while he was just a few miles away! As I searched the small patch of woods that corresponded to the last tracker location, I realized how challenging it would be to find this “eagle in the hay-stack”! Even with experience in spotting eagles, and having some ideas about the behavior of juveniles, where they might perch and what sorts of terrain they might be attracted to, actually seeing Duke would take a lot of patience and persistence, but most of all luck! To find him with good light in a spot where photos are possible, would take even more luck—what were the odds? Although through his transmitter he is being tracked, the data downloads only once every 24 hours, so I only knew where he had been, not where he was in real time!
“Duke” and an immature female feeding on a deer carcass 11/24/20 @ Barb McKee
I have been blessed to have seen Duke about a dozen times in the last eleven weeks. There have been many other times when I was probably looking right at him without seeing him and this is supported by the information from the tracker! A human playing “hide and seek” with an eagle is definitely at a visual disadvantage! I have learned that young eagles prefer wooded cover, small valleys with tiny streams where they might find a rodent or reptile. They tend to perch near water, not large rivers, but rather small creeks in narrow gorges or beside farm ponds. In winter, the best find for a hungry young eagle is a road-killed deer or other animal in a farm field that is fresh, but already immobile. A find like this keeps Duke perched and roosting close by until the food is consumed. I have seen many competitors for this precious winter commodity: vultures, other eagles, pesky crows, and at one site, even a coyote!

I also realized early on that Duke is just as likely to perch low and be almost invisible as he is to perch in a high tree top silhouetted against a light sky. Twice I flushed him off his perch because I was looking up not down. I learned that Duke has a favorite roosting spot where he has spent almost half of the nights he has been in central Jersey, but also discovered that he spent two nights within 100 yards of his natal nest in a small wooded area at Duke Farms!
“Duke” perched on Duke Farms property 1/5/21 @ Barb McKee
I have taken hundreds of photos of Duke. The light isn’t always the best, and Duke is usually quite far away, but my photos and videos have shown a healthy and thriving almost-two-year-old who has learned to hunt and to defend his prey! He has also learned to be patient and careful, and to wait his turn, most notably when “sharing” a meal with much larger and thus more assertive young female juveniles! I have seen him scatter and chase the competition off his food on fields. I saw him try to “steal” something from a hawk in the air. I have seen him in flight, a sight I never tire of! I even saw him perched over the Millstone River in my own back yard, probably searching for fish! That was truly memorable!
“Duke” in flight 1/19/21 @ Barb McKee
Will Duke decide to stay here in central NJ? Will he eventually mate, build a nest, and have nestlings of his own here? I hope so! Evidence suggests that eagles do return to an area not that far from the area where they fledged and began the challenging journey from fledging to maturity. I hope to share Duke’s adventures for many years to come.
It is always exciting to receive a report of a New Jersey banded eagle, especially when it is from Duke Farms eagle cam. D/99 was resighted two years ago during the winter of 2019. The blog post Duke Farms Alumni D/99: All Grown Up, has all the details of those sightings.
D/99, January 2021 @ Kristen Branchizio
D/99 has been sighted again, this time in Freehold, Monmouth County. He was seen for several days feeding on a deer carcass along with a few other eagles.
D/99 was the youngest of three chicks in the 2014 Duke Farms nest. It’s amazing to see the “before” and “after” photos. The little fuzzy wobbling chick is now a full grown majestic adult.
D/99 and siblings, April 2nd, 2014
D/99 is now seven years old and could possibly have a mate and be nesting in the area. We hope to get more resightings of D/99 in the future to know that he is doing well and raising his own family.
In part one and two of this blog series we followed the Three Bridges eagle pair. The transmission tower where they had previously nested was replaced and a new nesting platform installed. The question was: would the pair return and use the new nesting platform? Eagle Project volunteers have been closely monitoring the tower and surrounding areas for the eagle pair. The eagles have not been seen at their old nesting tower. At one point it looked like they were building a nest on an adjacent tower, but the amount of sticks never increased. Then a new eagle nest was found in a tree about a mile away from the tower location.

After many observations by nest monitors it is believed that this is the Three Bridges pair. While we can’t be 100 percent certain, the fact that they haven’t been seen at their old nest location and that this new nest is close enough to be in their territory. It is not uncommon for eagle pairs to relocate their nest if there is disturbance to the nest site. While it is disappointing, the new nest platform might not go to waste. Nest monitors have seen immature eagles perched on the newly installed tower and nest platform.

immature on nest platform 1/9/21@ Barb Mckee
As the number of eagles’s nesting in NJ continues to increase, it only makes sense that a pair will eventually use the nesting platform in the future.
CWF along with the NJ ENSP are using NJ Eagle Trax to track, “Duke” a year and a half old eagle who was outfitted with a transmitter on May 25th 2019.
May 25, 2019. Duke with transmitter @Kathy Clark
The last update I wrote was on March 31st. and at that time Duke had headed up to his old nest site at Duke Farms and then flew back south to the Susquehanna. In April he ranged along the Susquehanna in Southern PA and the Chesapeake region in MD, he did make a quick trip up into PA and back to MD. Duke spent all of May along the Susquehanna River near the Cononwingo Dam.
On June 1st he made another big trip up to Duke Farms and his old nest site. On June 9th he started heading back south and spent the rest of the month along the Susquehanna River. He spent all of July and August along the southern section of the Susquehanna River.
The Conowingo Dam, just south of the PA/MD state line in Darlington MD, is a location that Duke has visited several times over the last few months. This is an area where eagles congregate during fall migration and the winter. It is a popular eagle viewing spot, so perhaps someone will be able to get a photo of Duke. He still has a few years left before he’ll set up his own territory and find a mate.
We have been following “Duke” on NJ Eagle Trax, since he fledged from the Duke Farms nest on June 15th, 2019. He spent January in the Chesapeake Bay region. February and March he was ranging around northern MD and southern PA. On March 21st he made a big move up to NJ and was very close to his old nest. The points show him at Bradley Gardens at 4:42pm and the next point, to the southwest, at 4:59. We don’t know where he was between those two points but was certainly close enough to pass over his old nest. He spent the night at Round Valley Reservoir and the headed south on March 22nd.
