Thanks to Dave Irons for identifying this little sparrow as a juvenile Chipping Sparrow. He says that Spizella sparrows retain this streaked plumage for a few months only. He explains in the comments after my post.
It was seen August 7, 2011, picking around on the ground in front of the barn. It did not hang out with the others eating seed I'd thrown out for them... California Quail, Spottted Towhee, Song Sparrow, House Sparrows. It was smaller and slimmer than the House Sparrows. I thought at first it was a Savannah Sparrow, but the ones we have on our northwestern Oregon farm in the foothills of the coast range usually have yellow lores. This bird had a notched tail, but it was long not short. I'd like to know what it is so am posting nearly all the photos I took in hopes someone will tell me why it is whatever it is.
