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.
Breeding season.—Forty-eight records of breeding span the period April 11 to June 10; the modal date for egg-laying is May 10 ([Fig. 5]). This sample is drawn from central and eastern Kansas, but includes records of breeding by some birds identified in the field as C. cafer.
Number of eggs.—Clutch-size is about 6 eggs.
Nests are piles of wood chips in cavities excavated in stumps and dead limbs of trees such as willow, cottonwood, mulberry, and catalpa, ordinarily about six feet above the ground.
Red-shafted Flicker: Colaptes cafer collaris Vigors.—This woodpecker is a common summer resident in western Kansas, meeting, hybridizing with, and largely replaced by C. auratus in central and eastern sectors. The vast majority of specimens taken in Kansas show evidence of intergradation with C. auratus.
Breeding schedule.—The few records of flickers identified in the field as C. cafer have been combined with those of C. auratus ([Fig. 5]).
Number of eggs.—Clutch-size is perhaps 6 eggs.
Nests are like those of C. auratus.
Pileated Woodpecker: Dryocopus pileatus (Linnaeus).—This is a rare and local resident in the east, in heavy timber. The species has been seen, chiefly in winter, in all sectors of eastern Kansas in recent years, but actual records of breeding come only from Linn and Cherokee counties. D. p. abieticola (Bangs) occurs in the northeast, and D. p. pileatus (Linnaeus) in the southeast.
Breeding schedule.—Eggs are laid at least in April.
