Bald eagles are New Jersey’s early birds. In the chill of winter, they’re the first to build nests and lay eggs.
Even in the short days of December, these early birds are busy gathering sticks, grass and other materials to build or repair their nests. Only two weeks into the new year, they start laying eggs.

The male at the Duke Farms nest is banded with a green NJ band, A/59. He is nineteen years old this season.
On March 24, 2000, at 2 weeks of age, A/59 was fostered from the Greenwich nest in Cumberland County to the Rancocas nest in Burlington County. On May 15, 2000 he was banded, a backpack transmitter attached and fledged on June 3. ENSP’s staff tracked A/59 until the transmitter’s signal was last recorded on October 22. You can read more details in the 2000 Bald Eagle Report. A/59 started nesting at the Duke Farms nest in 2006 and has been in the public eye ever since on the Duke Farms eagle cam.
We have an interesting update on one of A/59’s offspring, “Tiny” C/94, who has been nesting in CT since 2014. “Tiny’s” original mate was a Massachusetts banded female. In 2017 nest monitor Cyndi Pratt Didan, reported that he had a new mate with a green NJ band on her right leg. Cyndi was recently able to get a photo of the females band and we could read the code as D/15.
In 2010, D/15 was one of two female chicks banded at the Duke Farms nest. Yes, she is Tiny’s sibling. Tiny was banded in 2009. It is interesting that two eagles from the same nest in NJ ended up as a pair nesting in CT and that we are able to know this information via bands and the Duke Farms cam. Cyndi has not yet found where the pair is nesting but will keep us updated.

Mercer County is now home to two pairs of bald eagles and their nests. The discovery comes nearly three decades after the species nearly vanished from New Jersey.
“Bald eagles in particular were wiped out to where we only had one nest in all of New Jersey as recently as the 1980s, and it wasn’t even a successful nest. And now we have over 200 pairs of bald eagles,” said David Wheeler, executive director of the Conserve Wildlife Foundation of New Jersey.
Wheeler said pesticides and people led to the near extinction of bald eagles.
Friday, bird watchers came equipped with binoculars and cameras to catch a glimpse of one the nests located at Mercer County Park.
“To see the nature and the national symbol of the United States all right here in Mercer Park is pretty neat,” said Flemington resident Graham MacRitchie.
Nearly 70 people were part of a new educational walking tour run by the County Parks Commission.
This breeding season, the Mercer County Park Commission is pleased to announce that two pairs of bald eagles have chosen County Parks for nest sites, continuing their expansion in New Jersey and the greater mid-Atlantic region. To celebrate the resident eagles, the Park Commission, Conserve Wildlife Foundation of New Jersey (CWF), PSE&G and the Wildlife Center Friends have launched a partnership to provide bald eagle-themed programs.
The first free public event will be at Mercer County Park at the West Picnic Area on Friday, Feb. 8 from 1 to 3 p.m. Participants will meet with naturalist staff and walk to the viewing site, where interpretation on eagle nesting will be offered. Attendees will also have the opportunity to view eagle activity through a spotting scope and binoculars.

On Sunday January 13th, 2019 photographer, Bob Cook was taking photos of the ~20 eagles at a lake in a Mercer County park. He noticed that one of the eagles had a green tag on it’s right leg. After reviewing the photos it was established that the band was D/99.
D/99 is from the Duke Farms nest located in Somerset County. He and his two siblings grew up as a celebrities their every move being watched by viewers of the Duke Farms eagle camera. The three chicks were banded on May 12th, 2014. Measurements showed that there there were two males and one female, D/99 was the youngest male. All three fledged from the nest in June 2014.
Unfortunately, in August of 2014 we received a report that D/98, the oldest male, was found dead up in Maine. He most likely died of injuries that occurred during a fight with another eagle. This most recent sighting of D/99 is the first report of either of the two remaining chicks. D/99 will be five years old in April and reaching the age where he will be looking for a mate and establishing his own territory. It is always nice to know that a chick has survived to adulthood and most likely has come back to NJ to nest.

The Conserve Wildlife Foundation of NJ in partnership with the NJ Division of Fish and Wildlife, Endangered and Nongame Species Program, has released the 2018 NJ Bald Eagle Project Report.
“Two hundred-four nest sites were monitored during the nesting season, of which 185 were documented to be active (with eggs) and 19 were territorial or housekeeping pairs. Thirty new eagle pairs were found this season, 20 in the south, nine in central and one in the north. One hundred-twenty-one nests (66%) of the 182 known-outcome nests produced 172 young, for a productivity rate of 0.94 young per active/known-outcome nest. The failure rate was well above average with 61 nests (33%) failing to produce. The Delaware Bay region remained the state’s eagle stronghold, with roughly half of nests located in Cumberland and Salem counties and the bayside of Cape May County.”
The number of active nests has increased while the number of young eagles fledged has decreased since a high of 216 young fledged in 2016. During the 2018 eagle nesting season there was an abundance of cold, wet, windy and snowy weather which was the cause for a portion of the nest failures. As the eagle population increases, there are more eagles competing for territories. This can also be a contributing factor in nest failures. NJ is still in the range of 0.9 to 1.1 young per nest which is needed for population maintenance with a productivity rate of 0.94 young per known-outcome/active nest in 2018. The 2018 NJ Eagle Project Report has all the details on the project including telemetry, re-sightings and recoveries.
The success of the eagle project is due to the tremendous dedication of the NJ Eagle Project Volunteers. They monitor the nests in all types of conditions and education people about the eagles with enthusiasm.
THANK YOU
One person can make a difference!
Thank you.
“Bald Eagles have made an amazing recovery in NJ since the 1980s. Today the eagle population still faces challenges and one of those is lead poisoning. Lead in the environment is dangerous to eagles as well as humans, and is often deadly. Unintentional poisoning of eagles can occur when they scavenge gut piles from deer or other game species shot with lead ammunition. It takes just a tiny fragment of lead to sicken and kill an eagle. Each year avian rehabilitators receive eagles that are diagnosed with lead poisoning and most will die. There is no good treatment for lead poisoning.”

Some of New Jersey’s eagle pairs are getting an early start on the 2019 nesting season. Eagles in NJ will begin incubation anywhere from January through March. NJ Eagle Project volunteers usually report eagles back and working on the their nests in the late fall/early winter. But some pairs have already been spotted sprucing up their nests in preparation for the upcoming nesting season.

On August 20th, 2018 a resident of Monmouth Beach reported a young eagle that had been perching in the neighborhood and was possibly injured. NJ Eagle Project Volunteer Randy Lubischer, was able to respond and check out the situation. The bird was a hatch year eagle, which means it fledged during this nesting season. The eagle was feeding on a swan carcass and though Randy could get fairly close, the bird was able to fly a short distance and appeared to have an injury to its left leg. The eagle had been seen feeding on the swan carcass for the past few days, so it was assumed that its injury was keeping it from hunting and the bird would only get weaker over time.
