The really cool thing was that the Snow Goose was associating with a flock of resident CANADA GEESE which had already picked up a CACKLING GOOSE and a ROSS'S GOOSE. Ross's and Snow geese don't turn up every year on the coastside of San Mateo County. Cackling geese do, but they are uncommon. Having them all grouped together was great, but it was also the best viewing of a dark Snow Goose that I've ever gotten.
After I checked out the geese, I decided to look for the BLACK-AND-WHITE WARBLER that seems to be overwintering on a different spot on Pilarcitos Creek. Black-and-White is a good bird for this part of California. I don't find them every year. Glad I got another look at one. It wasn't too shy so I got a picture.

I'll post at least once more with my complete year list. That's it for now though.
