Tracking Chincoteague Bald Eaglets

On August 20, 2014, two young Bald Eagles were released at Chincoteague National Wildlife Refuge, Virginia. Both birds were rescued as eaglets in Chincoteague in May 2014 after their nest was destroyed in a storm. Prior to release, the eagles were fitted with GPS transmitters. Read more about the eaglets' history and rehabilitation here.

At the Wildlife Center, the eaglets were known as patients #14-0649 and #14-0650. Now, the young eagles will be known as C35 and C46. "C" represents Chincoteague, where the birds were hatched and later released. The numbers are the last two digits on the transmitter that each eaglet is wearing. Each transmitter has a five-digit number written on the side of it in permanent black marker so that the eaglets could possibly be identified at a distance. Eagle #14-0649 is C35; Eagle #14-0650 is C46.

Where are they now?

January 2019: It appears as though C46's battery is depleted, which isn't a surprise after four years of tracking!
UPDATE: January 24:  After five months without a check-in, we assumed that Bald Eagle C46’s battery was depleted – but this bird surprised us!

On January 25, C46’s tracker did a “data dump” for the past four months. We can see that this bird spent time in its usual territory of southern Delaware, southeastern Maryland, and the Eastern Shore/Chincoteague Island in Virginia.

The eagle made trips spanning between Georgetown, DE and Accomack County, VA, with a few visits to its natal territory on Chincoteague Island.

We don’t expect to get more data from this eagle’s journey, but perhaps we’ll be surprised again!

August 26: Scattered check-ins from the past month indicate that Bald Eagle C46 is in southern Delaware. Most recently, the bird checked in just south of Georgetown, Delaware.

July 15:  We’re approaching the fourth anniversary of Bald Eagle C46’s release [August 20]. As the GPS transmitters age, quality and frequency of data degrade; the batteries in the transmitters are not intended to last more than a few years.

In the past year, we’ve seen evidence of transmission failures with missing data and infrequent check-ins. Still, even the briefest check-ins are exciting, because they tell us that the eagle is still alive and moving around!

On July 15, C46 checked in near Cokesbury, Maryland near a patchwork of farmland.
