I live in Marin County and see many of the same birds as you do, of course. I live on the edge of Richardson's Bay so we see lots of herons and egrets, mallards, some shorebirds depending on the tides and the year.
Every spring a mockingbird comes and sets up a big racket in the neighborhood, frantically making one call after another. This year it isn't quite so close to our house but it's nice to hear him.
