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.

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!
