Union County Falcon Cam female, “Frida,” stands over her clutch.
Last Friday, Union County Department of Parks & Recreation Environmental Specialist Betty Ann Kelly sent us an exciting update on the Union County Falcon Cam.
It looks like our famous peregrine pair are officially expecting!
Great news!
As some of you know, the rooftop of the Union County Courthouse has been home since 2006 to a pair of peregrine falcons, a threatened bird of prey species. Our female, nicknamed “Frida” because of her large “unibrow” between her eyes (reminding us of the South American artist) has laid her first egg of the season on March 19th, 2021 at 9:45 a.m.!
We can expect possibly two or three more eggs over the course of the next few days with hatching occurring sometime in late April.
Go toucnj.org/falcon to catch a glimpse of the falcons and possibly the egg on our falcon cam!
We will keep you posted!

Just two days later, this past Sunday, we received even more good news!
Today at around 2:20 p.m. after what seemed like considerable effort, our female peregrine falcon laid egg # 2.
All is well.
We expect another egg or two in the next few days. When the last egg is hatched, both male and female falcons will consistently incubate.
By the way, this egg only looks bigger because of the camera’s wide angle lens.
The two Duke Farms bald eagle chicks peek out from under their parent to catch some sun.
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.
For every dark day there was always hope for a brighter future. Results from the 2020 New Jersey Osprey Project.

This was likely one of the most challenging, at least in recent years, in the history of the New Jersey Osprey Monitoring Project. From social distancing and working from home (with children) to severe wind events and dealing with the impacts of humans on ospreys, 2020 turned out to be quite the year. Overall, our work was largely unaffected by the global covid-19 pandemic. Most of our work is conducted outdoors and away from mass gatherings of people. It was important for us to ensure the safety of our volunteers and the general public safe.
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.

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.

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.
NJDEP & CWF REPORT RECORD NUMBER OF BALD EAGLE NESTS, WITH EAGLES CONFIRMED IN ALL 21 NJ COUNTIES
by Ethan Gilardi, Wildlife Biologist
Photo by Northside Jim
2020 was a record breaking year for Bald Eagles in New Jersey. Going from just one recorded nest in 1980, New Jersey’s Bald Eagles hit three major milestones this year in terms of new nests, locations and total nests monitored.
A record 36 new eagle nests were found in 2020. 22 nests were found in southern New Jersey, seven in northern New Jersey, and seven in central New Jersey.
This means that Bald Eagle are now confirmed to nest in every county in the state!
An astounding (and record breaking) 220 nesting pairs of eagles were also monitored in 2020. These pairs produced a total of 307 eaglets, with an additional 28 nesting pairs tracked to nests, but laying no eggs. Of the 210 known-outcome nests, an average of 1.46 young were produced per nest, exceeding the productivity rate necessary to maintain a stable population of 1.0 young per nest.
These numbers could not have been achieved or documented without the dedicated efforts of the almost one hundred volunteers with the Bald Eagle Nest Monitor program, managed by the Conserve Wildlife Foundation of NJ in partnership with the Endangered and Nongame Species Program. These volunteers conduct the majority of the nest-observation work vital to the Endangered and Nongame Species Program in tracking the population and nest distribution of our state’s Bald Eagles.
“The comeback of the bald eagle in New Jersey ranks among the most inspiring recoveries of endangered wildlife species anywhere,” said David Wheeler, Executive Director of the Conserve Wildlife Foundation of NJ. “The bald eagle’s return illustrates what is possible for many other rare species when you bring together proactive wildlife management, strong public investment, and the unparalleled dedication of biologists and volunteers.”
CWF thanks our dedicated volunteers and partners who make our bald eagle conservation work possible, including PSE&G, Wakefern Food Corp./ShopRite Stores, P&G, Wells Fargo, Mercer County Parks, Wildlife Center Friends, the American Eagle Foundation, and the Zoological Society of New Jersey.
In Part one of this blog series the Three Bridges eagle nest was removed from the transmission tower. The tower was then dismantled. The next step was the installation of the new tower. This tower design is different then the old tower which had a lattice structure on top where the eagles built their nest. Since this new tower didn’t have have the same structure to support a nest, an eagle nest platform was designed and built .

During the entire procedure the Three Bridges eagle nest monitors recorded the eagle pairs activities. They were often perched on the nearby towers watching the activity. Nest monitor Mary Ellen Hill saw one of the eagles fly over to the new pole and hover above before flying back to another tower.

On a cold, snowy day the eagle nest was placed into the nest platform. The nest platform was then hoisted up to the arm of the tower and bolted in place. Now we wait and see if the pair will return and nest in their “old” nest on the new nest platform and tower.

Thank you to all the Eagle Project volunteers who monitor this nest and PSE &G employees who have worked hard to finish this project before eagle nesting season.
April 21, 2020, Three Bridges adult with 2 chicks@ Daniel Kroon
The following was written by NJ Eagle Project volunteer, Daniel Kroon. He monitors this nest along with several other dedicated volunteers whose photos are featured in this blog.
The Three Bridges (Hunterdon County) eagle nest is located on the top arm of an electric transmission tower. This pair has successfully nested on the tower for the past five years. This line of towers is scheduled to be replaced with new monopoles and the work on it has recently begun. PSE&G is cooperating with the NJ Bald Eagle program to move this nest to a new pole platform. Unfortunately, the pair is already on territory and have been observed bringing a stick to the old nest. It is an interesting story of how these eagles are adapting to the human-created environment and how we are trying to accommodate them.
The pair at nest October 17, 2020 before work begins @ Mary Ellen Hill
On November 4, PSE&G removed the top of the tower, keeping the nest intact, and lowered it to the ground where they carefully removed the nest from the tower structure. The nest is stored in a shed and will be re-installed on a platform affixed to the new tower when it is erected. We hope the eagle pair accept their remodeled home.

We will follow up with part two of this story once the new monopole tower is installed and the nest is placed back up on the platform. We thank all the nest monitors, PSE&G and everyone involved to make this as successful as possible.
None of us could have predicted what would happen in 2020, and that’s certainly true for New Jersey’s bald eagles.
When our eagle volunteers joined me at our kick-off training in February, we prepared as usual to monitor known nests and educate landowners and the public about the importance of minimizing disturbance to our breeding pairs.
We never imagined how important eagles would become to so many people during the COVID-19 pandemic. Dozens of you shared the wonder you felt in seeing eagles fly overhead, some for the first time. Eagles became a sign of strength and resilience for those staying at home, as well as those venturing out to do essential work.
And New Jersey’s eagle population soared – both literally and figuratively – breaking records with more than 200 active nests (with eggs) and 300 young fledged – up from just one pair in the early 1980’s.
We can thank our devoted eagle volunteers for this year’s success, as well as the individual, foundation, and corporate supporters who came through with funding to support our tireless efforts.
Unfortunately, not everyone who gave in the past, or who expected to give this year, donated as planned. And we recently learned that we’re losing our largest project funder for the coming season.
That is why I’m asking you to donate today to help CWF raise $10,000 to help cover the shortfall. Two generous donors have each put up a $2,500 match, which means that the first $5,000 donated will be matched dollar for dollar.
While having the best season on record is exciting news for all of us, important work remains to be done. Eagles still face serious threats of habitat loss and disturbance. The increasing population will require an even larger team of trained volunteers to observe nesting behavior and determine egg laying, hatching, and fledging dates. It also means an increase in the number of injured eagles which will need help. All of this takes time and resources.
For my part, I’m happiest when I’m outside working with bald eagles as I have for 20 years. After all, I’m a biologist, not a fundraiser! But in this case, I’m reaching out to ask for your support for the Eagle Project. We have overcome financial challenges in the past with the help of people like you. Whether you have always supported this project, or have newfound appreciation for these majestic raptors, please help us to ensure that this incredible success story continues to inspire all of us!
