Abstract

Three plots in southwestern Missouri, an upland forest, a shrubby plot, and a cedar plot ranging from 1.3 to 1.4 ha were sampled for bird species diversity from late March through November, 1978. Breeding bird censuses were also conducted in each area during the nesting season. Overall bird species diversity (BSD) was highest in the cedar plot. Breeding bird diversity (BBD) was also highest in the cedar plot as cedar trees provided a greater number of nest sites. Nests built in cedar trees were analyzed to identify the factor responsible for nest-site selection. By virtue of species specific stimuli, it was suggested that three species of breeding birds in the cedar field partitioned nest-site resources on the basis of foliage density.
