Western Screech Owl
Once combined with Eastern Screech-owl, this species was accorded full species status in 1981. Western Screech-Owl thrives in varied habitats, from humid coastal forests to southwestern deserts. Where ranges meet in the Great Plains, screech-owls are best distinguished by voice. Western varies greatly in size and plumage; as many as 18 sub-species have been recognized.
VOICE Distinct pure, high, crescendo poo notes that accelerate like a bouncing ball coming to rest; tremolo like Eastern, often broken in middle.
