_Breeding schedule._--Twenty-two records of breeding span the period May 11 to July 10 (Fig. 8); the modal date for egg-laying is June 5, and 75 per cent of all clutches are laid in the period June 1 to 20. _Number of eggs._--Clutch-size is 5 eggs (4.5, 3-6; 15). Nests are placed in holes and niches in willow, red haw, elm, and a variety of stumps, about eight feet high (ranging from five to 20 feet), usually over water. A pair nested once in a gourd under the eave of a house in Winfield, Cowley County, and another pair in a tin cup on a shelf at a sawmill (Goss, ex Long, 1936). =Parula Warbler=: _Parula americana_ (Linnaeus).--This summer resident in eastern Kansas usually can be found in heavy woodland and flood-plain timber. Specimens taken in the breeding season and actual records of breeding come from Doniphan, Riley, Douglas, Montgomery, Labette, and Cherokee counties. Temporal occurrence is indicated in Table 17. _Breeding schedule._--Eggs are laid at least from mid-May to mid-June. _Number of eggs._--Clutch-size is about 4 eggs. Nests are placed in debris in root tangles along stream banks, and, presumably, in pendant arboreal lichens. =Yellow Warbler=: _Dendroica petechia_ (Linnaeus).--This summer resident is common in the east, in woodland and riparian growths. _D. p. aestiva_ (Gmelin) occupies eastern Kansas west at least to Barber County, but it is not known how far west representatives of this population breed. _D. p. morcomi_ Coale breeds in western Kansas. _D. p. sonorana_ Brewster, a name applicable to Yellow Warblers of the southwestern United States and northern Mexico, has been considered a "straggler" (Long, 1940) or probable summer resident (Tordoff, 1956; Johnston, 1960) in southwestern Kansas, on the basis of one specimen taken on June 24, 1911, at a point two miles south of Wallace, Wallace County. This specimen, which is pale, was identified in 1935 as _D. p. sonorana_ by H. C. Oberholser. Specimens taken subsequently from Cheyenne, Hamilton, and Morton counties in the breeding season can be referred adequately to _D. p. morcomi_. Probably the specimen of 1911 is a pale variant of _D. p. morcomi_ within its normal distributional range. _Breeding schedule._--Thirty-five records of breeding span the period May 11 to June 20 (Fig. 8); this probably is inadequate to show the extent of the season, and some egg-laying into July is likely to be found in the future. The modal date of egg-laying is May 25, and this is likely to be reliable. _Number of eggs._--Clutch-size is 4 eggs (4.2, 3-5; 29). Nests are placed about nine feet high (ranging from five to 20 feet) in crotches of trees and shrubs including willow, elderberry, cottonwood, crabapple, plum, and coralberry. =Prairie Warbler=: _Dendroica discolor discolor_ (Vieillot).--This rare, local summer resident occurs in deciduous second-growth. The only breeding records are from Wyandotte and Johnson counties.
