[Surnia ulula. Hawk Owl. None of the several sight records from Kansas is convincing to me. Reports from eastern Kansas indicating regular occurrence there of this far-northern species are surely erroneous and probably pertain to Short-eared Owls.]
* Speotyto cunicularia. Burrowing Owl. Common summer resident in west; irregular transient in east. Numbers seem to be decreasing.
Subspecies in Kansas: S. c. hypugea (Bonaparte).
