Rare Bird: Rusty Blackbird

Was foraging with a mixed flock of Red-Wing Blackbirds and Brown-Headed Cowbirds. Was foraging at and around the base of a feeding station. This individual flew a few seconds before the red-wings and brown-heads flew. There were two other individuals that followed directly behind this individual that were close by in front of the native wildflower plot. They were relatively the same size, but I could not ID them. Possibly 3 Rusty Blackbirds were in the mixed flock.
