Asio fammeus - Locally common in open country over plains, sloughs, and marshes. The "ears" are hard to see. Note the black patch near bend of the underwing and large buffy area on upper wing surface. Active before dark; flight is irregular. Wings are tilted upward like a harrier's. Barks during breeding season; otherwise silent.
