In Kansas this kite seems to prefer open and even barren terrain, in contrast with its habitat in forests of the southeastern states. Typical habitat of Kansas is that of the High Plains, dominated by a short-grass climax of blue grama (_Bouteloua gracilis_) and buffalo grass (_Buchloe dactyloides_), with sagebrush (_Artemisia_ sp.), prickly pear (_Opuntia_ sp.) and other somewhat xerophytic vegetation. In the Gypsum Hills of south-central Kansas near the Oklahoma border, the Mississippi kite finds habitat conditions exceptionally favorable. This is an area of broken topography, dissected by small steep-sided ravines, often with brush and scrubby trees on the slopes. At Meade County State Park groves of cottonwoods (_Populus deltoides_) provided abundant places for perching and nesting. At this locality an artesian well provided an abundant year round water supply, which was impounded into an artificial lake half a mile long and a little less than a quarter mile wide. Water was also impounded in a series of small ponds maintained for the benefit of fish and waterfowl. Along with other improvements extensive plantings of cottonwoods and other trees were made with relief labor in the nineteen thirties. Trees were scarce on the area originally, but by 1961 there were almost continuous groves in an area nearly two miles long and three quarters of a mile wide encompassing the lake and ponds and adjacent areas. In conversation at the Park in August 1961, Dr. C. W. Hibbard told me of his observations on the colony of kites since 1936 when his paleontological field work in that area was begun. He indicated an area of less than two acres west of the artesian well to which the colony had been limited in its nesting in 1936, because at that time few trees were available as nest sites. In subsequent years, as the trees in the artificially established groves increased in size and height, and other trees became established naturally where the impoundments had created favorably moist conditions, the nesting colony expanded in all directions, and the number of kites increased tremendously. When my observations were made in 1961, the nesting area was co-extensive with the cottonwood groves, and there were literally thousands of trees within the area that provided adequate sites for nests.
