9", Gregarious...the adult male is a robin sized blackbird, with yellow or orange-yellow head and breast; in flight, shows white wing patch. Female and immature male: smaller(female) and browner, most of yellow confined to throat and chest; lower breast streaked with white; white wing patch restricted or lacking. Song consists of low hoarse rasping notes and sounds like rusty hinges. Forages in farm fields, open country , feedlots. Often associates with other blackbirds in mixed flocks in fall and winter.
From what i can see this bird is not as aggressive as our own Red Winged Blackbird but still is not pushover.
