Eagle Battles In New Jersey

Thursday, November 20th, 2014

Wildlife Blogger Jim from Readings From The Northside was lucky enough to witness two bald eagles fighting over a deceased duck. He captured their battle on film and describes what he saw on his blog Readings From The Northside.

As the numbers of eagles increase in New Jersey, these type of disputes are becoming more common place. Eagles not only fight over food but territory as well. Several eagles have been found deceased or injured this past year due to conflicts with other eagles.

Tracking New Jersey’s Bald Eagles

Transmitters attached to juvenile eagles in 2014

Since 2011 ENSP and CWF have been following the movements of young eagles outfitted with transmitters that have fledged from the Merrill Creek nest in Northern NJ. Currently two eagles are being tracked.

During the summer of 2014 two juvenile bald eagles were fitted with a GPS tracking device (a wearable backpack). Biologists chose one eagle from Atlantic County (a male) and one from Cumberland County (a female) to be tagged in this telemetry study. The male hatched at a nest near Nacote Creek in Port Republic, and wears a green band with code D/95. The female is from a nest on the Maurice River; she wears color band E/05.

The male, named “Nacote” (D/95) had a transmitter attached at 8.5 weeks of age on May 6, 2014 and on May 22, he first moved away from the nest tree. He remained within about 1/4 mile for more than one week as he learned flying and landing skills. He made a bold northern movement in late July, and was in Canada until mid-October when he started heading south. He currently is in upstate New York.

The female,  named “Millville” (E/05)  was about 8.3 weeks of age when outfitted with the transmitter. The banding date was May 19, and she remained close to the nest until late July, venturing out to Delaware Bay marshes and back in early August. In mid-September she crossed the Delaware River into Delaware and then spent most of September along the Chesapeake Bay in Maryland before crossing over to Virginia. She headed back into Delaware recently.

An interactive map showing their current location can be viewed on our website.  It’ll be interesting to see where they end up this winter.




Update on Duke Farms Eagle Cam

Juvenile eagle, D-98 recovered dead in Maine

On July 27th the juvenile male, D-98, was found dead by residents of Little Sebago Lake in Maine. He was banded at six weeks of age along with his two siblings one male and one female at the Duke Farms eagle nest which was broadcast live online.

His body was found floating in the lake by residents who reported the band numbers to the National Bird Banding Lab. We then received the report that he was found dead and were able to contact the finders for more information. Residents of the lake which is NW of Portland, reported seeing him near an active eagle nest located on the lake. The nest had chicks which had fledged in early July. On July 25th residents reported seeing a juvenile with a green band sitting in a tree near a boat house;

“The youngster had been in a small tree next to our boat house for quite a long time when an adult, carrying a fish, swooped in over the folks sunning on the beach and attacked the young bird. It dropped the fish in the process. The adult flew off leaving the fish and the juvenile behind. Thanks to a cell phone photo, we know that the youngster had the band colors of the later retrieved juvenile”.

While we don’t know for certain we can assume that the juvenile’s death was in some part due to injuries that occurred when it was attacked by the adult.  It is always sad to report on the death of an eagle especially one that hundred’s of Duke Farms eagle cam viewers watched “grow-up”, but it is the reality of life in the wild. The mortality rate for first year eagles is fairly high as they are still learning to hunt and survive on their own.  It is very unusual to receive this much information on the details surrounding an eagles death.  D-98 made an approximately 390 mile trip up to Maine.  He probably found plenty of food at the lake which is why he was hanging around, but ended up in another eagles territory.  Hopefully the remaining two juveniles from the Duke Farms nest have better luck and survive their first year.


New Jersey Eagle Nesting in PA

the story of “Jersey Girl”

Each year biologists with the NJ ENSP & CWF band chicks at eagle nests though out NJ. Each chick gets a green (NJ) band on one leg and a silver federal band on the other.  The Green band indicates that the bird was banded in NJ and the letter over the number combination is recorded so we know where and when.  There are at least 20 pairs of eagles nesting in NJ where at least one of the adults is a NJ banded bird.  Over the past few years we’ve gotten reports of NJ birds seen in other states and if we’re lucky (and someone has a really good camera) the green band can be read.

We recently heard from Linda Oughton who lives in PA.  She  has a pair of eagles nesting near her home and was able to get a photo of the perched female with green band B/64.  She was able to tell us that this pair has been nesting for the past three years near her development in Montgomery County and raised and fledged four young for two of those years. They were active this season and had two chicks, which unfortunately didn’t survive due to the severe winter weather.  Before nesting in this tree they nested for three years at another location where they raised seven young.  The banded eagle is a female which is known because she is larger than her mate (female eagles are larger than the males).

B/64 was one of three chicks banded in 2004 at the Hopewell West nest which is located in Cumberland County along the Cohansey River. Linda has named  B/64 “Jersey Girl”  and she keeps everyone in the development where she lives informed about the nest. No doubt that this former NJ bird is well loved and protected.

Brochures now available

Bald Eagle Project Brochures.

The New Jersey Bald Eagle nesting population is on the rise with 148 nesting pairs monitored in 2013 and 177 young fledged.  As the eagle nesting population increases so do the incidences of eagles nesting in close proximity to humans and human activity. It’s exciting to have a pair of bald eagles nesting and people often want to get a closer look but this can cause disturbance to the nesting eagles and have detrimental impacts. Over half of NJ’s eagle nests are located on private property which makes it important to advise and educate land owners, land managers about living with eagles.

To address this issue CWF received a grant to produce two informational brochures about co-existing with bald eagles in NJ. One is a general brochure for anyone interested in eagles in NJ and the other is specifically for landowners/land managers with eagle nests located on their property.  The brochures contain information on eagle history, living with eagles as you neighbors, how to be a good eagle watcher or steward, as well as phone numbers for information and law enforcement. As the eagle project volunteers monitor their nests they will have these brochures available to educate interested people.
