Good photos of the Hermit Thrush, California and Spotted Towhee, Golden-crowned, Song, and Fox Sparrows, plus a few others. I also got a few shots of a European Starling in the Eucalyptus trees by the parking lot and some American Crows in trees up the ridge on the bay side. These weren't on your checklist.
The one shot of the sapsucker was from the back and didn't show the head, not as good as I would have hoped... The other shots all had tree branches and trunks obscuring the view so I didn't bother to post those.
