I birded Tower Grove Park for a short time this morning (approximately 11am), and found exactly two (2) RUSTY BLACKBIRDS among a flock red-winged blackbirds and brown-headed cowbirds very near the park entrance at Kingshighway. The rusties were foraging somewhat separately from the rest of the flock.
