=Henslow Sparrow=: _Passerherbulus henslowii henslowii_ (Audubon).--This is an uncommon and local summer resident in eastern Kansas, in grassland. Breeding records are from Cloud, Shawnee, Douglas, Morris, and Anderson counties. Temporal occurrence is indicated in Table 20. _Breeding schedule._--Eggs are laid in May and June. _Number of eggs._--Clutch-size is about 5 eggs. Nests are placed on the ground, usually in bluestem pasture, but in any case grasses. =Lark Sparrow=: _Chondestes grammacus_ (Say).--This is a common summer resident in grassland edge habitats. _C. g. grammacus_ (Say) breeds east of the Flint Hills, east of stations in Pottawatomie, Anderson, and Montgomery counties, and _C. g. strigatus_ Swainson breeds west of stations in Clay, Dickinson, Harvey, and Sedgwick counties; specimens from the intervening area are of intermediate subspecific character. Temporal occurrence is indicated in Table 20. _Breeding schedule._--Thirty-nine records of breeding span the period May 1 to July 20 (Fig. 9); the modal date for egg-laying is probably May 25, but the sample may not be reliable in this respect. _Number of eggs._--Clutch-size is 4 eggs (4.1, 3-5; 28). Nests are usually placed on the ground, in cover of pasture grasses, clover, thistle, milo maize, and soybean; there is one record of a nest one and one-half feet high in a small pine. =Cassin Sparrow=: _Aimophila cassinii_ (Woodhouse).--This is a common summer resident in open scrub and grassland edge, to the south and west of Wallace and Comanche counties. Specimens taken in the breeding season and actual nesting records are from Wallace, Hamilton, Kearny, Finney, Morton, and Comanche counties; the A. O. U. Check-list (1957) cites Hays, Ellis County, as a breeding locality, but it is doubtful that the species now occurs there. _Breeding schedule._--Eggs are laid in May and June. _Number of eggs._--Clutch-size is about 4 eggs. Nests are placed on the ground, at bases of small bushes. TABLE 20.--OCCURRENCE IN TIME OF SUMMER RESIDENT AMERICAN BUNTINGS IN KANSAS
