Timed count at 5:27 p.m. over an area about 100' N to S. and about 50 yards deep to the SW.

Usually at least 6 at a time visible.

No breeze, so they're just drifting through the trees, dropping in from much higher. We're on the rim of a bluff a few 100 yards from the Rio Grande and about 200' above the river.

Our street is a cul de sac and the big stand of trees creates a wind shadow that catches the roosts.

Edge of the front of the migration arrived right behind a rain squall that was very narrow and just left a trace of rain, then returned to still air.
