_Breeding schedule._--Twenty-two records of breeding span the period March 21 to July 10 (Fig. 7); the modal date for first clutches is April 15 and for second clutches June 15. _Number of eggs._--Clutch-size is 5 eggs (5.5, 5-7; 12). Nests are placed in crevices about five feet high (ranging from zero to nine feet) in trees (oak, cherry, and pear), boulders, and a wide variety of structures, some of them nestboxes, built by man; appropriation and modification of nests of Barn Swallows is known to occur. =Carolina Wren=: _Thryothorus ludovicianus ludovicianus_ Latham.--This common resident of southeastern Kansas in woodland understory and brushland is uncommon in the northeastern and south-central sectors. Stations of breeding all fall east of a line running through Doniphan, Riley, and western Reno counties. North and west of southeastern Kansas the Carolina Wren is in marginal habitat and periodically is reduced in numbers by severe winters. _Breeding schedule._--Fourteen records of breeding span the period April 11 to August 10; the modal date for laying is April 15, to judge only from the present sample. The species probably breeds also in late March and early April. _Number of eggs._--Clutch-size is 4 eggs (4.2, 3-8; 9). Nests are placed near the ground in stumps, and a wide variety of structures built by man, or in crevices in earthen banks. =Long-billed Marsh Wren=: _Telmatodytes palustris dissaëptus_ (Bangs).--This is an uncommon summer resident in eastern Kansas in and around marshes. Presumably breeding individuals occur east of stations in Doniphan, Shawnee, and Sedgwick counties, but actual records of breeding come only from Doniphan County (Linsdale, 1928:505). First dates of arrival in spring run from April 19 to 29 (the median is April 22), and dates of last autumnal occurrence are from September 26 to October 31 (the median is October 8). _Breeding schedule._--Eggs are laid from May to August. _Number of eggs._--Clutch-size is 5 or 6 eggs; the range is from 3 to 10 (Welter, 1935). Nests are woven of broad-bladed grasses, usually no farther than two feet from water or mud, suspended in vertical plant stalks or branches in marshes. =Short-billed Marsh Wren=: _Cistothorus platensis stellaris_ (Nauman).--This rare and irregular summer resident in northeastern Kansas occurs in wet meadowland. Breeding records are available from Douglas and Coffey counties. Temporal occurrence in the State is at least from April 29 to October 25; early dates are most likely of transients. _Breeding schedule._--Eggs are laid in late July and August. _Number of eggs._--Clutch-size is 6 or 7 eggs. Nests are woven of plant fibers and placed in vertically-running stalks and stems of grasses and short, woody vegetation, within two feet of the ground.
