Nests are made of marsh vegetation (arrowhead, cattail) and float on water.
Snowy Plover: Charadrius alexandrinus tenuirostris (Lawrence).—This summer resident is fairly common on the saline flats of central and south-central Kansas. Breeding records are from Barton, Stafford, Meade, Clark, and Comanche counties.
Breeding schedule.—Fifteen records show that eggs are laid in the period May 25 to June 20; the peak of laying seems to be around June 10.
Number of eggs.—Clutch-size is 3 eggs.
Eggs are deposited on bare sand.
Killdeer: Charadrius vociferus vociferus Linnaeus.—This summer resident is common throughout the State, in open country frequently near wetlands. A few individuals overwinter in Kansas, especially in the southern counties.
Breeding schedule.—The 29 records of breeding span the period March 21 to June 30; the modal date of laying is May 20. The distribution of completed clutches ([Fig. 3]) suggests that Killdeers are here double-brooded.
Number of eggs.—Clutch-size is 4 eggs.
Eggs are laid on the surface of the ground, frequently on gravel, field stubble, plowed earth, and pasture.
Mountain Plover: Eupoda montana (Townsend).—This is an uncommon and local summer resident in western short-grass prairie. Breeding records come from Greeley and Decatur counties.
