Bald Eagle Banding and Transmitter Attachment at Duke Farms

Sunday, June 2nd, 2019

Two bald eaglets at the site of our Eagle Cam at Duke Farms were recently banded by biologists from Conserve Wildlife Foundation (CWF) and New Jersey Department of Environmental Protection, Endangered and Nongame Species Program (NJDEP ENSP).

This year’s banding was special, as in addition to a band the male eaglet was also fitted with a transmitter which will allow him to be tracked on our Eagle Trax page.

Kathy Clark, (NJDEP ENSP), and Larissa Smith (CWF) wrote about the experience, and the benefits of transmitters on the Duke Farms blog. Their FAQ’s are reprinted below.

On April 8th, Kelly Hunt was photographing four bald eagles at Forsythe National Wildlife Refuge (NWR), two adult birds and two immature birds. When she got home and looked at the photos she realized that one of the young birds was banded and had a transmitter. It was “Nacote” back in his home area. “Nacote” was banded and outfitted with a transmitter on May 6, 2014 at the Galloway nest. Since then we have been tracking his movements on the CWF website. These photos give a great look at what the plumage of a bald eagle going into its third year looks like. You’ll also notice that the eyes and bill haven’t yet turned yellow.

Re-sighting New Jersey Eagles

Looking for green bands.

by: Larissa Smith, wildlife biologist/volunteer manager

One way we can track eagles is with transmitters which I’ve discussed in previous blogs. Since 2011 three eagle chicks have been outfitted with satellite transmitters to track their movements. Two of the birds have since died. To follow the movements of the third eagle go to

Another way to track eagles is by banding them.  The NJ Endangered and Nongame Species Program has been banding eagles with green (NJ specific) bands since 1987.  Eagles are banded when they are six weeks of age and get a green NJ band on one leg and a silver federal band on the other.  The state band has a letter over a two digit number. The band information is entered into the National Bird Banding Lab database and when someone finds an injured or dead eagle they can report the band. Most of the information that comes in from these bands are from dead or injured birds. The bands tell us when and where the the bird was banded. By using spotting scopes people can sometime see that a bird has green band but many times are unable to read the number.  We know that  23 pairs of eagles nesting in New Jersey have at least one bird in the pair that was banded in NJ.

Sometimes we are lucky to get re-sightings from photographers with high powered lenses who can focus in on the band.  Just in the past week we’ve gotten three sightings of NJ birds.  One eagle has been seen on Long Island with a green band and reported by Peter Stegemann. He has seen this bird all last summer and fall with another eagle and they might be nesting this season. This would be the first pair of eagles to nest on Long Island since DDT wiped out the eagle population. By zooming in on the photo ENSP principal biologist Kathy Clark was able to read the letter and first number as C/8.  The second number couldn’t be read but by going through the banding records it was determined that this eagle was banded in 2009 at the Princeton nest.

Another NJ banded bird (D/64) was photographed by Justin Pursell in Schwenksville, PA on April 7th, 2013. The eagle hasa nest in the area.  The bird was banded May 10, 2004 at the Hopewell West nest in Cumberland County.  Kristen Nicholas took a photo of a third  year NJ banded bird at Lake Tappan Northern NJ/Lower NY on March 20, 2013. The green band is D/39  a third year male which was banded in 2011 at the Oradell Reservoir in Bergen County NJ.

While it’s great to get re-sightings of NJ banded birds we don’t want to get them at the expense of the eagles. These photos were taken by photographers with high powered lenses. People should view eagles from a safe distance so as not to disturb them, especially when they are nesting.  Disturbance to a nest can cause the eagles to abandon the eggs/young or cause the young to prematurely jump from the nest.
