Ring-billed Gull delawarensis TC08 adult, December 29 2015, Sunnyside Beach, Toronto. Picture: Alvaro Jaramillo.

Amanda Guercio banded this bird, yellow TC08 as an adult on February 03 2014 at Sunnyside. Wing/head/culmen/etc measurements suggested female.

These birds are part of a winter site monitoring project of gulls on the Great Lakes. This project started winter 2013 and run by the Tommy Thompson Park Bird Research Station, and the Toronto and Region Conservation Authority Looks like these birds have come back to the site they were banded at.
