These records are intended to be a continuation of the winter bird lists of the Upper Missouri Valley, started in 1916 by Dr. T. C. Stephens, of Morningside College. Later Mr. Charles J. Spiker, of New Hampton, Iowa, published the winter records from 1922 to 1926, and the present paper begins at the latter year.
