Nests are placed about 20 feet high in crotches near trunks or heavy branches of such trees as red cedar, elm, oak, osage orange, cottonwood, honey locust, box elder, and pine.
Black-capped Chickadee: Parus atricapillus Linnaeus.—This resident is common north of the southernmost tier of counties, in forested and wooded areas. P. a. atricapillus Linnaeus occurs chiefly east of the 98th meridian, and P. a. septentrionalis Harris occurs west of this; a broad zone of intergradation exists between these two subspecies. Breeding schedule.—Fifty-one records of breeding span the period March 21 to June 10 ([Fig. 7]); the modal date for laying is April 15, and 64 per cent of all eggs are laid between April 11 and 30.
Number of eggs.—Clutch-size is 5 eggs (5.4, 4-7; 10).
Nests are placed in cavities about ten feet high (ranging from four to 20 feet) in willow, elm, cottonwood, honey locust, apricot, or nestboxes placed by man.

Carolina Chickadee: Parus carolinensis atricapilloides Lunk.—This resident is common in the southernmost tier of counties, from Comanche County east, in forest and woodland edge. Actual records of breeding are from Barber and Montgomery counties.
Breeding schedule.—There are no data on breeding of this species in Kansas.
Number of eggs.—Clutch-size is about 5 eggs.
