Abstract
For twenty consecutive years I have taken the Christmas Bird Census which is sponsored annually by the magazine Bird-Lore. All these censuses were taken in northeastern Iowa. This series of December bird lists, covering a twenty-year period, forms a good index to the winter bird life of northeastern Iowa. During the twenty years forty-six species have been observed. With the exception of a half dozen or so rather rare winter visitants or residents, this number includes all the winter birds I have recorded in this locality.
