Any idea where this gull was tagged? The tag looks to be S894. It was photographed by a friend of mine in Duluth MN. Its a Herring Gull that seems to have it’s first winter plummage.
Thoughts? Thanks
@Sandy Gordon: Any birds with bands or tags can be reported here and they will get back to you when they figure out where it was marked. http://www.pwrc.usgs.gov/BBL/bblretrv/
