In 1969, nine survey routes were established in Ellis County, Kansas, to assess populations of breeding birds. Surveys were conducted during the years 1969-81 and 1985, for a total of 207 surveys. The number of surveys was reduced to 114 when cut-off points were set for time and date. Data were analyzed for total number of individuals, total number of species, and for 12 of the more common species in the county. Testing revealed no overall patterns for total number of individuals or total number of species. Minor population cycles were suggested for some of the individual species. The factor with the greatest effect on this study was observer bias.
