Birds of the foothill woodland community

This study is concerned with density of the bird population expressed as the actual number of non-breeding birds and the pairs of potential breeding birds living on thirty-tree and a third acres in the Foothills Woodland Community at the Experimental Range, Madera County, during the winter and spring of 1953. Generally a study of the density of the bird population is usually concerned with one or the other types of investigation, but since the writer kept records during the non-breeding and breeding season both results are included in this paper.
