Rare Golden Eagle Tracked Through Migration

A rare golden eagle that was rehabilitated after it was found wounded in New York last year has been tracked since its release all the way back to where it was originally found.

The eagle was found in Amenia, N.Y., by snowmobilers in February 2011. It had suffered multiple puncture wounds on its left leg, likely caused by an animal it was trying to capture. Its left foot was also injured. It was transferred to the Tufts Wildlife Center in North Grafton, Mass., for treatment and made a full recovery.

Last March, it was released from Tufts, but not before Todd Katzner, a research assistant professor at West Virginia University who studies the species' migratory habits, outfitted it with a GPS-GSM telemetry unit and a tracking band.

While the golden eagles are not endangered, they are rarely seen in the eastern parts of North America. Sightings in New York and New England are exceedingly rare, and occur only during migrations. The birds are often 50 percent larger than bald eagles, with wingspans that surpass 7 feet (2 meters).

The tracking data has revealed the bird’s flight pattern over the past year: After its release, the bird remained near Amenia for about two weeks before beginning its northern trek, traveling not far from the St. Lawrence River, and then crossing part of the Labrador Peninsula into the northern reaches of Quebec. As winter set in, the golden eagle then headed south, resting near the area where it was found.

Data now reveals that the bird has begun its return northward to the Quebec/Labrador breeding grounds.

"It's extremely gratifying to all of us here at Tufts Wildlife Clinic to learn that this beautiful bird is doing well and living out its life in the wild, as it should be," said Dr. Florina Tseng, director of Tufts Wildlife Clinic.
