I live in west Sonoma County in California and I've identified two new birds this week around my house (so hard to get pictures of them though):
In addition to the robins, towhees, scrub jays, crows and hawks I already knew about, I've identified a white breasted nuthatch that must have chicks in a birdhouse next door. I've been watching it bring back food every few minutes in the evenings.
A pair of red or purple (can't tell yet) house finches have been discussing housing on our front porch, and just began building a nest just outside our front door.
I just installed two new feeders and three new bird houses in the trees. So far the squirrels haven't been able to get into the food :)
