You could have seen some younger crows? Were they begging? It's common
in late summer/early fall to see and hear young crows that are fledged
and probably able to take care of themselves but still want mom and pop
to take care of them, so they will sit and beg for hours. Or could you
be seeing both American and Northwest crows. Northwest crows are a
little smaller. Since I've lived in the PNW most of my life, I assume
that I've seen Northwest crows frequently, but when it comes to certain
identification, I sure wouldn't want to stake my life on telling them
from Americans.

Maybe someone could enlighten us further on relative sizes of fledged
current year brood vis-a-vis adults.
