Abstract

For the past four years I have maintained a bird trapping station in the back yard at my home in Iowa City for the purpose of securing birds for banding. Two government sparrow traps, built after the design and specifications set forth in United States Department of Agriculture Circular 170 (April, 1921), have been in more or less constant operation. Through the agency of these traps, the position of which has been shifted only slightly from time to time, I have taken between April 3, 1923, and January 1, 1923, a total of 112 birds representing six species.
