This gull was on the wall at the control
gates at Chippawa, above Niagara Falls, Ontario on 28 November 2013.
It has yellow legs, a mantle several shades darker than Herring, and
is about the same size as surrounding Herring Gulls. It has limited
winter head streaking and some blotchiness on the neck. It was first
seen on Saturday 23 November 2013 and has generated much discussion
about its identity. Photos have been sent to Yellow-legged Gull
experts in Europe for their opinions.
