=White-necked Raven=: _Corvus cryptoleucus_ Couch.--This summer resident is common in western Kansas, probably occupying locally favorable sites in prairie grassland and woodland edge west of a line from Smith to Seward counties. The species is known to nest in Cheyenne, Sherman, and Finney counties. _Breeding schedule._--There are few data from Kansas; Aldous (1942) states that the birds begin activities leading to building sometime in April in Oklahoma; the peak of egg-laying probably occurs in May, which coincides with the records from Kansas. _Number of eggs._--Outside Kansas, this species lays 3 to 7 eggs; these figures seem applicable to Kansas, where brood sizes are known to run from 1 to 7 young. Nests are placed about 20 feet high in cottonwood and other trees. =Common Crow=: _Corvus brachyrhynchos brachyrhynchos_ Brehm.--This resident is common in most of Kansas, but numbers are lower in the west. Distribution in the breeding season is west at least to Cheyenne, Logan, and Meade counties. _Breeding schedule._--Sixty-nine records of breeding span the period March 10 to May 31 (Fig. 7); the modal date for egg-laying is April 5, and 60 per cent of all eggs are laid between March 21 and April 10. _Number of eggs._--Clutch-size is 4 eggs (4.2, 3-5; 19). 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.

See legend to Figure 1 for explanation of histograms.] =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. Nests are placed in cavities of trees.
