August 1, 2021. It is raining and dreary out. Indoors all day wrapping up my end-of-season raptor time/mileage sheets, I have cabin fever! Tracking Duke for the last nine months has been educational and fun, and right now I know that he is nearby. For the last week he has been perching along the Raritan river–very close to my home and adjacent to his natal home, Duke Farms in Hillsborough. I have been too busy to spend as much time as I would like hiking and biking along the river nearby, while playing “hide and seek” with Duke! I check the internet link for today’s confirmation. Sure enough, Duke is perched in a wide-open field on Duke Farms land that I know well. It is only 4 miles away so I get in the car and head over there. Because it is raining, my chances of spotting him might be pretty good since eagles prefer not to fly in the rain, but rather remain on their perches without moving. He might still be there! I anticipate success. There he is! Right where I thought he would be. In a small grouping of trees in the middle of this large field there is one dead tree front and center, and Duke, fortunately, is perched on the dead tree, easily seen from the road. The photos are shot from about 100 yards away, in a light rain, but it is still a thrill to see him as it has been exactly two months since I last saw him on June 1st. blog post (Playing Hide and Seek with an Eagle)

On August 2, I learned that Duke had flown from that Duke Farms field back to the Delaware River and to Tohickon Creek where he spent the first week in August. As the second week began, his transmitter skipped 2 consecutive days of downloading data, but and when it finally did download, he had flown back to Duke Farms! In the coming days he seemed restless. He did not hunker down in one area, but appeared to be revisiting all of his haunts and hang-outs in central Jersey from the last nine months. He even went back to Tewksbury, flew very close to his winter “restaurant”, the game fowl pens at Flint Hill Hunting Preserve, and did a huge circle over Bedminster! He checked out Round Valley, the Black/Lamington River, Eagle Bend on the North Branch, and explored that river from Far Hills all the way to route 22. Then on August 30, a travel day again, he flew back to the Delaware! Again his transmitter did not connect with the satellite on the last day in August, but when it finally did connect, it was clear that his restlessness continued.

During the torrential rains of hurricane Ida, Duke finally hunkered down in PA on Neshaminy creek west of Washington Crossing in a rural area of woods and fields. He remained there until Sept. 6 when he flew back to the Delaware River and perched right near my Bulls Island nest. That is where he was on Sept 7. Then….his transmitter skipped three days of downloading! Finally, on Sept. 10, 72 hours of data downloaded and it showed he had been back on Tohickon Creek. This is a wild stream in a wooded gorge. There are some roads and houses here and there, but it is mostly rural–a good place for a young eagle. There would be plenty of places to perch and roost, and fish and small animals in and by the river to eat. But then, after 3:03:08 pm Eastern Daylight Time on September 10, his transmitter went dark!

My adventures with Duke started exactly a year ago today! blog post (Duke’s Homecoming) I learned he can hold his own against competition for food, aggressively steal from lesser raptors, find small rodents, reptiles and other prey in the smallest of creeks and valleys, fly beautifully and roost safely during rain, wind and snow. I have watched him thrive as an independent eagle in the wild, and although I sometimes worried about his choice of perches and food sources, I believe he has a great chance of reaching maturity and, in about 2 years, with his head and tail feathers mostly white, find a territory he likes and a mate with whom to build a nest. I miss knowing where he has been and miss our games of hide and seek. It has been 57 days since his last data download. I trust from the information on the site that his solar battery has failed and that Duke himself has not failed! During the coming winter I will be searching all the places I know he preferred. I believe eagles are creatures of habit. As I watched him travel around, sometimes all the way to the Chesapeake and back, I am sure that he used his eagle eyes to spot landmarks which are his “road maps” when he travels. I have plenty of reason to believe that he will return to his favorite roosts and hang out and I will have my eyes open, still searching for him. My sincere hope is that I, or someone else, will someday catch a photo of him with his E/88 band easily readable!

In the meantime, soar safely Duke, fly high and free.

The 2021 New Jersey eagle nesting season was another good year for NJ’s eagle population. The final numbers and details will be available in the 2021 Annual Bald Eagle report published in December. There are over 100 eagle project volunteers who monitor eagle nests/s during the season. They are an extremely dedicated group who not only monitor eagle nests but help to protect the nests. Volunteers become familiar with their pairs and get to witness all kinds of eagle (and other wildlife) activity. I asked the volunteers to send me their one favorite photo from this season.

This is the second year that the NJ Endangered & Nongame Species program along with the Conserve Wildlife Foundation of NJ have set up a “soft release” area for juvenile eagles that were found grounded and cared for at Rehabilitation centers. The site is in a remote area of Cumberland County where staff and volunteers provide supplemental food (fish and road-killed mammals) in a safe place, and where other juvenile and sub-adult eagles would provide the social learning they needed. Trail cameras were installed to document eagle use.

This eagle nesting season we have been following the story of the Three Bridges eagle pair in a blog series. A camera on the nest allowed viewers to get an up-close view of the nesting activities. The pair successfully raised two chicks, who biologists banded (green bands H/04 & H/05), and they fledged the end of June.

On July 4th, eagle H/05, was found injured near the nest. He was taken to The Raptor Trust where he was treated for a fracture of the left coracoid bone, which supports powered flight in the wing. He remained in the care of The Raptor Trust until he was fully healed and had regained some of his flight strength.

Three Bridges nest monitors continued to observe the nest area and determined that the adults and H/04 were still around the nest platform. In a very quick and quiet manner, H/05 was released back at the nest site last past week. It was necessary to have adults in the area, so he can continue his post-fledging period with them, learning to hunt and survive on his own.

Since his release, H/05 has been seen flying and perching in the nest area. It is very important for people to view the nest platform from a distance and not approach the nest tower or any eagles perched in the area. We all need to keep this nest area “eagle-safe” for the next month, giving H/05 and his family time to reacquaint and re-learn eagle skills! We thank everyone who has supported this eagle family.

“Jersey Girl” is a NJ banded eagle (B/64). She was reported to us in 2014 by Linda Oughton, who has been keeping track of her and her mate since 2010. They nest is in Montgomery County, Pennsylvania. B/64 was banded in 2004 at a nest in Cumberland County NJ, located along the Cohansey River. ‘Jersey Girl” is seventeen years old.

I started writing the Three Bridges blog series at the end of November 2020. At the time we had no idea if the eagle pair would return to the newly installed nest box, nest somewhere else or nest at all this season. In the last blog post Part 5, the eggs had hatched. Since that last blog a lot has happened at the nest. On April 2nd nest monitors determined that hatching was occurring and on April 14th it was determined that there were two chicks. On May 14th, the nest was visited by PSE&G and NJ Division of Fish and Wildlife, Endangered and Nongame Species Program. The chicks were banded with silver federal bands and green NJ bands H/04 and H/05. Both chicks were determined to be males. During the nest visit the camera was fixed and a whole new close up view of the nest appeared.

Cam viewers got to watch the young eagles as they learned to feed themselves and started preparing their wing muscles for flight, by flapping and hopping around the nest. When eagles are nesting in a tree the young will perch on branches which is called “branching”. In this case the chicks don’t have any branches, so the perches were built as substitute branches. Nest monitor, Mary Ellen Hill, got the below screen shot of one of the chicks perched for the first time. The young eagles also used the metal arm of the pole for perching.

On June 20th, H/04 took his first flight and his brother H/05 followed on June 22, all of which was caught on camera. Eagle Project volunteer Diane Wilson Cook has made a webpage, Bald Eagles at Three Bridges with the video clips from these flights. The fledges have been returning to the nest platform since fledging. The parent’s are still bringing food to the nest for the young eagles as they will be in the nest area for the next few weeks as they learn to hunt and survive on their own.

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.

• 

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!

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!

• 

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!

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 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 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.
