Gulls at the Marathon landfill

I did a quick swing through the Marathon Landfill this afternoon. There were about 300 gulls present although there was lots of turnover during my 20 minute stay. There were no Ring-billed Gulls yet. I enjoyed up-close views of four Glaucous Gulls and my first Great Black-backed Gull for the Thunder Bay District.

Glaucous Gulls, first and second year?

Glaucous Gull, adult.

Great Black-backed Gull, third year.

Otherwise, I haven't noticed any new arrivals. The flock of finches visiting out backyard feeders has diminished to about 90 birds comprised of Common and Hoary Redpolls, Pine Siskins, Purple Finch and Evening Grosbeaks.
