Number of eggs.—Clutch-size is about 4 eggs.
Nests are secured by means of a salivary cement to vertical surfaces, usually near the inside tops of chimneys in dwellings of man, but occasionally in abandoned buildings and hollow trees.
Ruby-throated Hummingbird: Archilochus colubris (Linnaeus).—This is an uncommon summer resident in eastern Kansas, and is rare in the west, in towns and along riparian vegetation. Temporal occurrence in the State is listed in [Table 12].
Breeding schedule.—Eight records of breeding fall within the period May 21 to July 10; there seems to be a peak to laying in the last third of June.
Number of eggs.—Clutch-size is 2 eggs.
Most nests are on outer branches of shrubs and trees, in forks or on pendant branches, 10 to 20 feet high.
Belted Kingfisher: Megaceryle alcyon alcyon (Linnaeus).—This summer resident is common throughout the State in streamside and lakeside habitats. Timing of arrival and departure of the breeding birds is not well-documented owing to the fact that the species is also transient and a winter resident in the State.
Breeding schedule.—Eggs are laid at least from April 21 to May 20.
Number of eggs.—Clutch-size is near 6 eggs.
Eggs are laid on the floor of the chamber at the inner end of a horizontal tunnel excavated in an earthen bank. The tunnel is two to six feet long and many tunnels are strewn with bones and other dietary refuse.
