Any time you find a banded bird, even if its a common one like a Canada Goose, give these folks at the USGS a holler. I found a banded Yellow-eyed Junco a few weeks ago on Mt. Lemmon, and yesterday I heard back with a nifty certificate and some fun information about the bird. Now I feel like I know it so well! It's still only a hunch, but I'm pretty sure this bird's name is LeRoy.
It's important to take notes or get a photo of all the bands (this particular bird had plenty) as the ordering and coloration of the bands tells the banders different specifics about each individual.
Meet LeRoy (also known as specimen 2030-27116). He is about four years old, he has yellow eyes, he was banded in July of 2011 by Dr. Conway, and he likes long walks on the beach.
