Abstract

On 17 June 1982, a census of birds was taken on a section of farmland in Woodbury County, Iowa, to repeat earlier censuses in 1916 and 1926. A total of 41 species and 359 individuals were counted; 19 species were common to all three censuses. In general, between-year comparisons show great similarity in the bird life for the three censuses. Farmsteads, riparian and pastures (in this order) were the habitat classes with highest bird densities. The three most abundant species (House Sparrows, Barn Swallows and European Starlings) were found on farmsteads; the next two most common species (Western Meadowlark and Grasshopper Sparrow) were prairie species found in pastures.
