New Mexico State Bird Tee/Navy on Antique White - Women's
The New Mexico State Bird T-shirts are adorned with the state of New Mexico shape, the New Mexico State bird - the Greater Roadrunner, and the American Birding Association's four letter "Banding Code."
GRRO - is the ABA's banding code for the Greater Roadrunner. 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.
