_Breeding schedule._--Twenty-three records of breeding are from May 21 to July 10 (Fig. 5); the modal date for egg-laying is June 15. _Number of eggs._--Clutch-size is 3 eggs (3.4, 2-5; 22). Nests are placed in forks, crotches, and occasionally near trunks, chiefly of willow, from 4.5 to 12 feet high (averaging six feet). =Eastern Wood Pewee=: _Contopus virens_ (Linnaeus).--This summer resident is common in the east, but is rare in the west. Preferred habitat is in edge of forest and woodland. Temporal occurrence is indicated in Table 13. _Breeding schedule._--Nineteen dates of egg-laying span the period June 1 to July 20 (Fig. 5); the modal date for completion of clutches is June 15, and more than half of all clutches are laid in the period June 11 to 20. _Number of eggs._--Clutch-size is about 3 eggs. Nests are placed on upper surfaces of horizontal limbs of oak, elm, and sycamore, about 22 feet high. =Horned Lark=: _Eremophila alpestris_ (Linnaeus).--Breeding populations are resident in open country with short or cropped vegetation. _E. a. praticola_ (Henshaw) lives in the east, and _E. a. enthymia_ (Oberholser) in the west. _Breeding schedule._--Twenty-one records of breeding span the period March 11 to June 10 (Fig. 6); the modal date for egg-laying is March 25. The histogram (Fig. 6) is constructed on a clearly inadequate sample, and records of breeding both earlier and later are to be expected. The peak of first nesting activity is probably reasonably well-indicated by the available records. _Number of eggs._--Clutch-size is 3 eggs (3.6, 3-5; 16). Nests are placed on the ground, usually amid short vegetation such as cropped prairie grassland or cultivated fields (notably soybeans and wheat), and occasionally on bare ground.
