Subspecies in Kansas: Following reported: _O. a. naevius_ (Gmelin) in northeast, _O. a. hasbroucki_ Ridgway in south-central, _O. a.
aikeni_ (Brewster) and _O. a. swenki_ Oberholser in west. The status of these subspecies is poorly known; additional breeding specimens and revisionary study are needed.
* _Bubo virginia.n.u.s._ Horned Owl. Common resident throughout state.
Subspecies in Kansas: _B. v. virginia.n.u.s_ (Gmelin) in east, _B. v.
occidentalis_ Stone in west.
_Nyctea scandiaca_ (Linnaeus). Snowy Owl. Rare and irregular winter visitant throughout state.
No subspecies recognized.
[_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).
* _Strix varia._ Barred Owl. Resident in east, locally fairly common.
Status in west not known.
Subspecies in Kansas: _S. v. georgica_ Latham in southeast; _S. v.
varia_ Barton elsewhere in state.
* _Asio otus._ Long-eared Owl. Uncommon summer resident, locally common transient and winter resident throughout state. Nesting records from Ottawa, Douglas, Doniphan, and Meade counties. Status in summer poorly known.
Subspecies in Kansas: _A. o. wilsonia.n.u.s_ (Lesson).
* _Asio flammeus._ Short-eared Owl. Resident, probably throughout state, in suitable habitat. More common in winter. Nesting records from Woodson, Republic, and Marshall counties.
Subspecies in Kansas: _A. f. flammeus_ (Pontoppidan).
* _Aegolius acadicus._ Saw-whet Owl. Rare winter resident throughout state. One nesting record: a pair found in Kansas City, Wyandotte County, in winter, 1950, remained at least to September, 1951, and were seen with young birds in summer, 1951, John Bishop.
Subspecies in Kansas: _A. a. acadicus_ (Gmelin).
* _Caprimulgus carolinensis_ Gmelin. Chuck-will"s-widow. Locally common summer resident in eastern Kansas, western limit of distribution poorly known.
No subspecies recognized.
* _Caprimulgus vociferus._ Whip-poor-will. Locally common summer resident in eastern Kansas; two specimens reported from Finney County, but status in west poorly known. Two nests reported, at Geary, Doniphan County, June 16 and June 14 to July 3, 1923, by Linsdale. In recent years, Chuck-will"s-widows seem to have increased at the expense of Whip-poor-wills in Kansas.
Subspecies in Kansas: _C. v. vociferus_ Wilson.
* _Phalaenoptilus nuttallii._ Poor-will. Summer resident, common in west, rare and local in east.
Subspecies in Kansas: _P. n. nuttallii_ (Audubon).
* _Chordeiles minor._ Nighthawk. Common transient and summer resident throughout state.
Subspecies in Kansas: Nesting; _C. m. minor_ (Forster) in northeast, _C. m. chapmani_ Coues in southeast, and _C. m.
howelli_ Oberholser in west, intergrading with one another through fairly broad zones. Migration; _C. m. sennetti_ Coues throughout state.
* _Chaetura pelagica_ (Linnaeus). Chimney Swift. Common transient and summer resident in east; status in west poorly known. Schwilling reports this species only in migration in Finney and neighboring counties.
No subspecies recognized.
* _Archilochus colubris_ (Linnaeus). Ruby-throated Hummingbird. Common transient and summer resident in east; much less common in west, status there poorly known.
No subspecies recognized.

No subspecies recognized.
* _Megaceryle alcyon._ Belted Kingfisher. Common summer resident and uncommon winter resident throughout state.
Subspecies in Kansas: _M. a. alcyon_ (Linnaeus).
* _Colaptes auratus._ Yellow-shafted Flicker. Common resident throughout state, but partly replaced in west by Red-shafted Flicker and hybrids between the two species.
Subspecies in Kansas: _C. a. auratus_ (Linnaeus) in southeast, _C.
a. luteus_ Bangs in remainder of state. _C. a. borealis_ Ridgway has been reported in winter in east.
* _Colaptes cafer._ Red-shafted Flicker. Common resident in west, hybridizing with, and replaced by, Yellow-shafted Flicker eastward.

Subspecies in Kansas: _C. c. collaris_ Vigors.
* _Dryocopus pileatus._ Pileated Woodp.e.c.k.e.r. Formerly common resident in eastern Kansas, now much reduced in numbers and distribution. Recent sight records from Leavenworth, Wyandotte, Douglas, Miami, Linn, and Neosho counties may indicate that this species is increasing in its former range. Definite nesting records only from Linn County where Frank Wood and Ivan Sutton found a nest with 4 eggs and a nest with two young and one egg, along Marais des Cygnes River, near Pleasanton, some years ago. Eunice and Wilson Dingus have noted this species at Mound City, Linn County, regularly for several years.
