Tree Swallow, Banded
This bird has what appears to be a U.S. Federal band on its left leg. I didn't notice the band until I loaded the image into the computer. If I'd seen it in the field, I would have zoomed in to get the numbers on the band. The band appears to be a standard aluminum butt-end band.
Here's some info on bird bands from the Bird Banding Lab pages on the USGS' (United States Geological Survey) site:
"The most common type of band used in North America is the butt-end band. This band is a round band with two edges that butt evenly together when closed correctly. Butt-end bands are supplied by the Bird Banding Laboratory to licensed US banders free of charge."
I think this is the first banded Tree Swallow I've seen. I plan on learning more about Tree Swallow banding.
