All about Bald Eagle Transmitters

BE 629-30172 trans1-001
Folks know that Alice is the adult female at the Bald Eagle nest along Overpeck Creek Ridgefield Park because you can sometimes see the transmitter strapped to her back.

But we've never been able to see a transmitter like hers fairly up-close until now, under some unfortunate circumstances.

Kathy Clark of the state's Endangered and Non-game Species Program reported last week that a Bald Eagle  "was recovered dead on Picatinny Arsenal in mid-May.  Necropsy report boils down to impact trauma.  The bird was still wearing an old-style backpack transmitter."

New York State found that "the bird was hacked in the first year of the NYC project [2002] at Inwood Park [in Manhattan].  It was a 7-week-old wild nestling from Wisconsin.  It was banded 629-30172 and A62 and outfitted with a Telonics 3 year backpack."

Kathy reports that the transmitter "certainly looks older than 13 years, being a solid metal case. Looks like an old clunker."

Alice was hacked in Inwood Park in 2004 and outfitted with a similar transmitter.

"It may have lost padding that would have been against the bird's skin," according to Kathy.  "It weighs 72g, which is nearly exactly what the new satellite tags weigh (70g plus harness)."
