Passer domesticus
We are seeing lots of juveniles -- many House Sparrows, some American Robins, House Finches, and Canyon Towhees. Even though there are lots of birds around, it's officially summer now and all the plants have filled out with leaves to the extent that I rarely can get pictures of them (or even see them) when they hide deep in the bushes. The noisiest of the lot are the House Sparrows, and occasionally we'll see Mom out feeding seed to three or four little ones (all of whom are chattering endlessly).
