Sounds like not much is known about the nature of early autumn song in
WEME.
Regarding the Townsend's Solitaire winter song - you will notice the
song on my Stokes guide was from Oct., done in a patch of
juniper-pinyon, far downslope from their mountain breeding grounds.
Your Solitaires may also sing from time to time between their tooting.
Mine toot most of the day but sing intermittently. When several are in
close proximity (on good feeding grounds) they sing, toot, and chase
each other quite a bit in an aggressive manner.

The BNA monograph includes the following statements on page 11:
"Becomes gregarious in loosely constituted flocks, sometimes up to 200
birds, in fall and winter; remains in flocks until the following spring.
Flocks may also include Eastern Meadowlarks. No winter territoriality
(Lanyon 1953, Bent 1958). No published evidence for dominance hierrchies
in
winter flocks."
