Minnesota State Bird Tee/Light Blue on Navy - Men's
The Minnesota State Bird T-shirts are adorned with the state of Minnesota shape, the Minnesota State bird - the Common Loon, and the American Birding Association's four letter "Banding Code."
COLO - is the ABA's banding code for the Common Loon. When ornithologists band a bird in the field, they use this code to document the record. Many avid birders have adopted this abbreviated system, and now refer to the subjects of their sightings by these codified call-signs.
