Nests are placed in cavities of trees.
Tufted Titmouse: Paras bicolor Linnaeus.—This resident is common in the eastern half of Kansas, in woodlands. Specimens taken in the breeding season and nesting records come from east of a line running through Cloud, Harvey, and Sumner counties, and the species probably breeds in Barber County.
Breeding schedule.—Twenty-two records of breeding span the period March 21 to June 10 ([Fig. 7]); the modal date for laying is April 25, and 54 per cent of all clutches are laid in the period April 11 to 30.
Number of eggs.—Clutch-size is 4 to 5 eggs (4.5; 6).
Nests are placed in cavities about 12 feet high (ranging from three to 30 feet) in elm, oak, cottonwood, hackberry, redbud, osage orange, and nestboxes placed by man.
White-breasted Nuthatch: Sitta carolinensis Latham.—This resident in eastern Kansas, in well-developed woodland, is uncommon. S. c. cookei Oberholser occurs east of a line running through Douglas and Cherokee counties, on the basis of specimens taken in the breeding season and actual nesting records, and S. c. carolinensis Latham occurs in Montgomery and Labette counties. S. c. nelsoni Mearns has been recorded in Morton County but probably does not breed there.
Breeding schedule.—Eggs are laid in March and April; young have been recorded being fed by parents throughout May.
Number of eggs.—Clutch-size is between 5 and 10 eggs.
Nests are placed in cavities about 30 feet high in elm and sycamore.
House Wren: Troglodytes aedon parkmanii Audubon.—This summer resident is common in the east and uncommon in the west. Preferred habitat is in woodland, brushland, and urban parkland. House Wrens arrive in eastern Kansas in the period April 3 to 27 (the median is April 19), and are last seen in autumn in the period September 19 to October 13 (the median is September 30).
