A quick note that this evening a Prairie Merlin flew over Canyon Lakes Golf Course in San Ramon. This is my first in Contra Costa and is surprisingly not flagged. The powder blue back and orange strea

Hi all, Got out to a few spots today. Don't have much to report that hasn't already been said, just a few quick things. Birded Jewel Lake today in Tilden from about 750-9. I was hoping for a good show
