On the Numbers and Local Distribution of Illinois Land Birds of the Open Country in Winter, Spring, and Fall

Abstract

Is has been our general plan to work at first with broad strokes of the full brush, refining upon our neutral background by degrees and endings, as we hope to do in a paper following the present one, with the final details for each species taken up separately and followed all over the state and around the year.  This one time more, however, we must resume our method of blocking in the skeletal outlines and the basal features of the local ornithology, as intelligently as we can with somewhat inadequate materials, leaving it to others to give life and finish to the sketch.
