Coyote 736 was a healthy, young male that was trapped and collared on the southwest side of Chicago on June 2, 2013. His tail had a unique deformity — short, with a twist that resembled a pug's tail, so beginning his nickname of "Pug" (although we don't normally name coyotes, sometimes nicknames help our researchers communicate with the media when referring to animals). We were very excited to learn from this animal given his location. Pug traversed some of the most urban, rugged streets of Chicago and didn't seem to draw attention anywhere.
