Family STRIGIDAE: Owls

Eastern Screech-Owl, Otus asio [R -, r, -, - O]
 Eastern Screech-Owls are rarely found at Cedar Creek. In most years they are probably absent. Howitz heard one south of the laboratory only once. Residents report occasionally hearing a Screech-Owl in the Cedar Creek vicinity. Save for the Barred and Great Horned Owls, the status of the other owls at Cedar Creek is very poorly known.
