Another productive year for NJ’s eagles

The Conserve Wildlife Foundation of NJ in partnership with the NJ Endangered and Nongame Species Program has released the 2017 NJ Bald Eagle Project Report.  In 2017, 178 eagle nests were monitored during the nesting season. Of these nests 153 were active (with eggs) and 25 were territorial or housekeeping pairs. One hundred and ninety young were fledged. (more…)

W34: A NY Banded Eagle In NJ

Bands help to tell his story.

In the end of October, NJ Eagle Project volunteer Randy Lubischer spotted a banded adult bald eagle near his home in Monmouth County. He was able take good photos that showed the bird was banded with a blue (NY) band on the left leg and was able to get a very clear image of the letter and number code on the band. We reached out to the NY Division of Fish, Wildlife and Marine Resources to find out more information on the eagle.

In the fall of 2011, an injured hatch year bird was found on the side of the road in Onondaga County, NY. The bird was rehabbed,  banded (NY Blue band W34) and released on October 7, 2011 at the Montezuma NWR.  On 11/18/2016, W34 was sighted in Darlington, Maryland and then in in NE Maryland again on 3/1/2017.

W34 looks to be staying in NJ to nest as he has found a mate, a sub-adult female, who still has dark feathers on her head. They have started to build a nest and have been copulating.

We can’t necessarily assume that W34 was hatched in NY. Since he was found injured and not banded he could well be a NJ bird. We have followed NJ recent fledges outfitted with transmitters, take long flights north after leaving their nest areas.  We also know that many NJ banded eagles do return to NJ to nest. So we’ll never know the true origin of W34 but we can piece together some of his story and hopefully have more news about him and his mate in the upcoming nesting season.

Continuing To Track NJ Eagles

Saturday, September 2nd, 2017

by: CWF biologist Larissa Smith

We keep track of all re-sightings we receive of NJ (green) banded eagles. This information is important as it lets us know where eagles raised in NJ go after leaving the nest and eventually where they end up nesting. In 2017 we have had NJ banded birds sighted in NJ as well as PA and VT.

On April 15, 2017 Mary Dunham photographed NJ banded D/18 near Lake Como in Belmar, NJ.  The female was banded in March 2011 at the Manasquan Reservoir, Monmouth County. She was with another smaller adult, assumed to be a male. While Mary  watched a third adult eagle came into the area and the pair chased it away. This is an indicator that D/18 was paired up and perhaps was nesting in the area.

D/18 @ Mary Dunham

In August we received a report that D/18 was sighted once again. This time she was up near the NY- Canada border. We don’t know much about the movements of nesting eagles so we can only speculate why she made such a big move north. Perhaps she went north with a recent fledgling or maybe she was kicked out of the pair by an intruder eagle and headed north?

D/40@ Reid Hoffer

In March we were contacted by Reid Hoffer who monitors an eagle nest along a reservoir in Rockland County NY.  He was able to get a photo of a green band, D/40, she was banded May 2011 at Newton Reservoir in Sussex County. Mr. Hoffer reports that unfortunately the pair did not produce any offspring this year.

Telemetry

We are also currently tracking three NJ eagle with transmitters attached.  The New Jersey Bald Eagle Tracking project shows the movements of all three of these birds as well as their history.

Two of the transmittered birds  fledged from Merrill Creek Reservoir in Warren County, NJ. Harmony 2, has spent the last four years in a 100-mile swath of western Connecticut and Massachusetts. She fledged in 2012 making her a 5th year bird and breeding age. We suspect she’ll nest in the same area next season.  Haliae fledged in 2013 and has spent the past three years mostly around the Eastern Shore of Maryland. Perhaps she’ll stay in that area to nest? So two birds from the same nest, but one has settled to the north and one to the south.

Nacote, a male from the Galloway nest in Atlantic County, has stayed more “local” to his home area. He’s spent the last three seasons in Atlantic, Cumberland and Cape May Counties. He favors the CMC landfill and local sand pits where other eagles are known to roost and feed.

All this information helps us to locate roost and foraging areas and protect them.  It’s also fascinating to know where NJ eagles go after leaving their nest area, especially when they begin nesting. Why do some head north, others south and yet others stay near their “home” range? We don’t know, and that’s ok, it’s what makes them wild!

“Jersey Girl” Update

Monday, June 19th, 2017

B/64 and mate have a successful 2017 nesting season.

CWF Biologist: Larissa Smith

B/64 & mate@ L. Oughton

In 2014 I first heard from Linda Oughton who watches an eagles in nest near Montgomery, PA. The female in the pair is a NJ banded bird, B/64, nick named “Jersey Girl”. She was banded in 2004 at the Hopewell West nest along the Cohansey River in Cumberland County.

This season Jersey Girl and her mate raised and fledged three chicks. Linda reports that they have fledged a total of 14 chicks since they first started nesting in 2010. It isn’t often that we know what happens to one of NJ eagles and we can only know if they were banded as chicks.  Unfortunately many of the NJ banded eagles that are reported to us are either injured or dead. But in recent years re-sightings of green banded NJ birds are more common and we are aware of NJ banded eagles nesting in NJ as well as NY and CT.

Fallen Eagle Nest, Leads To Eagle Rescue

Saturday, June 10th, 2017

and one lucky eagle chick.

Larissa Smith, CWF Biologist

Friday afternoon before Memorial Day weekend I received a call from one of the Eagle Project volunteers, Heiki Poolake. A nest which him and his wife Donna monitor, had fallen out of the tree and the chick was on the ground. The chick was approximately 9 weeks old so still several weeks away from fledging (leaving the nest). On the ground the chick was susceptible to predators. While the adults were in the area and keeping an eye on the chick they most likely weren’t feeding the chick on the ground.  One option would be to build some type of “nest” back up in the nest tree. That option would require a climber and their weren’t any available. The next option was to install an osprey platform at the site and place the chick in the platform. We have done this successfully in the past when an eagle nest had fallen.

Eagle chick on ground 5/26/17@ D. Poolake

ENSP Principal biologist Kathy Clark, CWF volunteer Matt Tribulski , the Poolakes and myself all met out at the site.  The platform was installed close to the original nest tree with extended perches to allow the chick to “branch”.  It was determined that the chick was in good health, no broken bones or other issues from the fall. The chick was banded with a silver federal band and a green NJ Band E/50. Measurements were taken which helped to determine that the chick was a female and almost 9 weeks of age. She was fed some fish since we were unsure when she was last fed and placed in the nest platform along with more fish.

The Poolakes went out the next day and found her once again down on the ground and placed her back in the nest.  The fish we had left were gone which was a good sign she was eating. She remained in the nest until  June 8th when she was perched on the branch of a near by tree.  Both adults were also perched close by, keeping an eye on her.  At this point she was approximately 11 weeks old around the time when chicks her age start to branch and practice flying. She’ll stay in the area for the next few weeks with the adults as she learns to hunt on her own and strengthen her wings.  The first year is tough for eagles as they learn to survive on their own. We wish E/50 luck and hope to see her nesting in NJ someday.
