The second picture presents a direct side-by-side comparison of E. californicalis and E. ocellea (3 individuals each; all observed at the same place and night) as I currently understand it. The main difference is the location of the dark line (marked by a red arrow in the top photos) within the surrounding white field. (Please, note though that there is no guarantee for this to work, and there seem to be counterexamples on BOLD.)
Based on this ID method, I have found E. californicalis only in one small area (Yolo Bypass) where others also have seen it. In contrast, E. ocellea is much more broadly distributed.

This tan striped White-throated Sparrow is one and only white throated sparrow wintering this year in my yard. The other sparrows are 20+ White-crowned, 8 Golden-crowned, 1 Lincoln's and 1 Aleutian sooty
Fox sparrow.

LARGEST male Bullfrog (easily 2 to 3 pounds) that I have seen in 50+ years. Could easily swallow Mouse, Blackbird, Crayfish, or small Snake. No smaller Bullfrogs in the immediate area - probably all swallowed.
