The blue head is obvious and this flock is made up of dimorphic birds, unlike the Common Grackles below: "The female [common grackle] averages slightly smaller and duller in plumage, but the distinction is not as dramatic as with the other grackles" (Tveten p. 332). The contrast in the members of the flock and the blue head convince me that this is a Brewer's Blackbird.
