=Common Nighthawk=: _Chordeiles minor_ (Forster).--This is a common summer resident throughout Kansas. Temporal occurrence is indicated in Table 11. Three subspecies reach their distributional limits in the State, _C. m. minor_ (Forster) in northeastern Kansas, _C. m. chapmani_ Coues in southeastern Kansas, and _C. m. howelli_ Oberholser west of the Flint Hills. _Breeding schedule._--Twenty-two records of breeding span the period May 11 to June 30; the modal date for egg-laying is June 10 (Fig. 5). _Number of eggs._--Clutch-size is 2 eggs. Eggs are laid on the ground in rocky or gravelly areas, on unpaved roads, or on flat, gravelled tops of buildings of man. =Chimney Swift=: _Chaetura pelagica_ (Linnaeus).--This is a common summer resident in eastern Kansas, around towns. Temporal occurrence in the State is indicated in Table 12. _Breeding schedule._--Thirty-six records of breeding span the period May 11 to June 30; the modal date for egg-laying is May 25 (Fig. 5). _Number of eggs._--Clutch-size is about 4 eggs. Nests are secured by means of a salivary cement to vertical surfaces, usually near the inside tops of chimneys in dwellings of man, but occasionally in abandoned buildings and hollow trees. =Ruby-throated Hummingbird=: _Archilochus colubris_ (Linnaeus).--This is an uncommon summer resident in eastern Kansas, and is rare in the west, in towns and along riparian vegetation. Temporal occurrence in the State is listed in Table 12. _Breeding schedule._--Eight records of breeding fall within the period May 21 to July 10; there seems to be a peak to laying in the last third of June. _Number of eggs._--Clutch-size is 2 eggs. Most nests are on outer branches of shrubs and trees, in forks or on pendant branches, 10 to 20 feet high. =Belted Kingfisher=: _Megaceryle alcyon alcyon_ (Linnaeus).--This summer resident is common throughout the State in streamside and lakeside habitats. Timing of arrival and departure of the breeding birds is not well-documented owing to the fact that the species is also transient and a winter resident in the State. _Breeding schedule._--Eggs are laid at least from April 21 to May 20. _Number of eggs._--Clutch-size is near 6 eggs. Eggs are laid on the floor of the chamber at the inner end of a horizontal tunnel excavated in an earthen bank. The tunnel is two to six feet long and many tunnels are strewn with bones and other dietary refuse. =Yellow-shafted Flicker=: _Colaptes auratus_ (Linnaeus).--This is a common resident and summer resident in eastern Kansas, meeting, hybridizing with, and partly replaced by _Colaptes cafer_ westward, in open woodlands. _C. a. auratus_ (Linnaeus) occurs in southeastern Kansas, and _C. a. luteus_ Bangs occurs in the remainder, intergrading west of the Flint Hills with _C. cafer_.
