CGORS only bands raptors. Sometimes non-raptors are caught during operations. These birds are identified, recorded, and released without a band. Over the years, CGORS has captured over 150 species of birds. You can view a collection of photos at eBird.
NOTE: All banding, marking and sampling is being conducted under a federally authorized Bird Banding Permit, issued by the U.S. Geological Survey’s BBL. All birds are immediately released to the wild after processing. Photographs of birds in the hand are taken with the utmost concern for the birds health and well-being.
