The writer has published three papers in the Proceedings of this Academy dealing with the winter bird life in the Missouri River region during the years from 1916 to 1920. More recently Mr. Chas. J. Spiker has published a paper on the same subject dealing with the years from 1922 to 1926. The present paper is intended to bridge the gap between these two periods and to place in permanent form a few very interesting and important records of the bird life in the region dealt with.
