=House Sparrow=: _Passer domesticus_ (Linnaeus).--This sparrow, introduced from stocks in Ohio and New York (originally from England and Germany), has been present since about 1876 in eastern Kansas; it is a common resident in towns and at farmsteads throughout the state. Nomenclaturally, House Sparrows in North America consistently have been referred to the European ancestral stocks, _P. d. domesticus_, but none in North America today duplicates morphologically the European birds. This is evidence of meaningful adaptation of the North American populations to environments in which they now live, and continued use of _P. d. domesticus_ is misleading. Studies on local differentiation in North American House Sparrows are in progress, and when the biology of sparrows in the midwest is better understood, suitable nomenclatural proposals will be made. _Breeding schedule._--Fifty-one records of breeding span the period March 20 to July 20 (Fig. 8); the modal date for laying of first clutches is April 5, and for second clutches May 5. _Number of eggs._--Clutch-size is 4 eggs (3.9, 3-7; 13). Nests are placed in niches of various sorts seven to 50 feet high in buildings, nestboxes, and trees, or freely situated in forks and crotches of large trees. =Bobolink=: _Dolichonyx oryzivorus_ (Linnaeus).--This species is a rare and local summer resident, in and about grassy meadows. There are but two stations of breeding in Kansas: Jamestown State Lake, Cloud County, and Big Salt Marsh, Stafford County. Temporal occurrence is indicated in Table 18. _Breeding schedule._--Eggs are laid in June. _Number of eggs._--Clutch-size is about 5 eggs. Nests are placed on the ground amidst grasses. =Eastern Meadowlark=: _Sturnella magna_ (Linnaeus).--This summer resident and resident is common in eastern Kansas, in moist grassland. _S. m. argutula_ Bangs occurs in Montgomery, Labette, and Cherokee counties and intergrades to the north and west with _S. m. magna_ (Linnaeus). Good numbers of birds are found east of the Flint Hills, but to the west the species is of restricted and local distribution. Extreme outliers of the species are found no farther west than stations in Jewell, Stafford, and Barber counties. _Breeding schedule._--Forty records of breeding span the period April 10 to July 20 (Fig. 8); the modal date for egg-laying is May 5. Fifty-seven per cent of all eggs are laid in the period May 1 to 20. _Number of eggs._--Clutch-size is 5 eggs (5.2, 4-7; 26). Prior to May 11, clutch-size is 5.3 eggs (13 records), and after that date it is 5.1 eggs (13 records). Nests are placed on the ground, with cover of grasses or forbs. =Western Meadowlark=: _Sturnella neglecta neglecta_ (Audubon).--This is a common resident and summer resident in western Kansas, and is restricted and local in the east; preferred habitat is in grassy uplands.
