Dear Tweeters,
Today, the 18th December 2023, there was an odd gull with 560 Bonaparte's Gulls at Barcelona Harbor, Western NY. That's on the Great Lakes, Lake Erie, to be precise.
If we had anything comparable to Tweeters over here, I'd post this to a local list-serve, but we don't.
Here's the link to my eBird checklist.

I'd love to hear from any gull aficionados as to their best ideas on ID. I have some ideas of my own, but would love to hear what others think.
Yours truly,
Gary Bletsch
