Black-chinned Sparrow on Kitchen Creek Road

I didn't find my first Black-chinned Sparrow until 2014, the first spring after I moved to San Diego. I see it about 5 times a year now, in the montane chaparral with dead tree limbs sticking above it--just like the photo below.

The bouncing ball song is like an Orange-crowned Warbler and Wrentit song merged together.
