=Blue Grosbeak=: _Guiraca caerulea_ (Linnaeus).--This is a common to uncommon summer resident in most of Kansas, in brushland and streamside thickets. _G. c. caerulea_ (Linnaeus) breeds in the east, east of stations in Douglas, Greenwood, and Cowley counties, and _G. c. interfusa_ Dwight and Griscom breeds in the west, west of stations in Cloud, Stafford, and Clark counties; a broad zone of intergradation exists between the two named populations. Temporal occurrence is indicated in Table 19. _Breeding schedule._--Seven records of breeding span the period May 21 to June 30; the modal date of laying seems to be in late May or early June. _Number of eggs._--Clutch-size is about 4 eggs. Nests are placed from three to 30 feet high in a variety of deciduous plants.

The species extends westerly, in riparian situations, in reduced numbers, ultimately meeting and hybridizing with the Lazuli Bunting. Specimens referrable to the Indigo Bunting have been taken as far west as Finney County, but most specimens from that far west show evidence of interbreeding with Lazuli Buntings. Temporal occurrence is indicated in Table 19. _Breeding schedule._--Twenty-four records of breeding span the period May 11 to August 20 (Fig. 8); the modal date for egg-laying is June 15. _Number of eggs._--Clutch-size is 3 eggs (3.1, 2-4; 17). Nests are placed about three feet high (ranging from one to nine feet) in coralberry, sumac, thistle, sycamore sprouts, hickory sprouts, grape, elderberry, cottonwood, dogwood, ragweed, and grasses.
