Last night dumped a lot of White-crowned Sparrows in my Solvang backyard, and
I just photographed a dark-lored one. Per [Lehman] this should either be Z. l. oriantha (likely) or Z. l. leucophrys (less likely). Another bird was either Z. l. pugetensis or Z. l. nuttalli, but I did not yet manage to photograph that one.
Advice on how to separate between those subspecies is welcome.
