More Bay Area Slaty-backed Gulls.
Unfortunately, this is not one that one can chase - but no matter, Half
Moon Bay is the most reliable place to see this species nonetheless. The
bird I located today was in a private area in the SF Bay Area, if accepted
it will be a new county record. I apologize for the secrecy; it is just the
way it has to be. Here are photos of the bird:
Keep watching the large gull flocks in the Bay Area, I am sure there are
many Slaty-backed Gulls that have not been found yet and birds are moving
through right now. This has been an amazing year for this species in the Bay
Area, and it likely is due to an invasion. There have also been good photo
records from Newfoundland, Ontario and Texas this year! I predict we will
get an echo flight next year, but unless there is a range expansion into
North America (as Lesser Black-backed Gull did earlier), this year may go
down as a banner one for this species which will be very difficult to
