Very common in this area. Picking and flying away with acorns at this time.
Mixed flocks, mostly White-crowned Sparrows with a couple Golden-crowned Sparrows in among the grassland and dried thistles.
This male/buck was staying within several yards/meters of a female/doe. I concentrated on photographing the male and later noticed in my photos that his tongue was frequently out.
Fall color foliage, covered with Lace Lichen (Ramalina menziesii)
Late migrant, first-year bird
You can certainly detect the Yellow-Billed part in this pair of lousy pictures
