Pennsylvania State Bird Tee/Red on Red - Men's
The Pennsylvania State Bird T-shirts are adorned with the state of Pennsylvania shape, the Pennsylvania State bird - the Ruffed Grouse, and the American Birding Association's four letter "Banding Code."
RUGR - is the ABA's banding code for the Ruffed Grouse. 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.
