Dickcissel gets its name from the male's Spring song - "dick dick ciss ciss ciss". This neotropic migrant breeds primarily in central U.S. grasslands. Formerly breeding in many Atlantic states, they were extirpated by 1900. In recent years they have begun to reestablish themselves in small pockets in the East. Rare individuals are seen every Fall around Brooklyn and NYC, usually within flocks of House Sparrows.
