During the fall and winter of 1953 the writers undertook a general ecological study of a portion of the Palouse River valley, near Armstrong, Whitman County, Washington. During the course of these investigations records were kept on the numbers of birds observed and the vegetation in which they were located. It was anticipated that these observations might indicate bird-use of the major vegetational types found in the area. Several investigators (Dumas 1950; Wing 1949) have published distributional data for birds of the Palouse grassland during the nesting, period, but few have been concerned with distribution patterns during the fall migration.
