This white crowned sparrow decided to be a holy terror this morning.
The house finch didn't give up, however, and got a bath in.

Go listen to some good music: "Territories" from the album Power Windows by Rush. I didn't catch them, but a black phoebe, and what looked like a California towhee were in on this little territorial battle, too. I don't know where the male Anna's hummingbird--who believes he has sole ownership of the fountain--was when all this was going on.
