I smelled trouble stirring early last week when I read the weekend forecast calling for upper 40-degree temperatures in the Chicago area. Both Saturday and Sunday made it above 50F, with a high of 54 degrees recorded on southern Lake Michigan today (14 Dec 2014). To top it off, overcast skies dominated all of Saturday and most of the day Sunday.
Despite a notable absence of gulls at some of our better gull-watching sites, I still managed to see all five of our winter species with a bit of effort!

A shot of both the sub-adult Thayer's and the Glaucous in one frame...not the best photo, but it captures the day's highlights for me:
Here's a nice hatch year Ring-billed to conclude this post. Note how well it's holding on to its juvenile flank, chest and neck feathers. Most similar-aged RBGU's have for some time now shown mostly whitish feathers here, with variable streaking on the head and hindneck that's not as extensive as this:
