adventures in backyard birding, Solvang, 2020-09-05

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.
