Abstract

For a number of years, during the summer and fall months, thousands of bronzed grackles and many starlings, cowbirds, and robins have come daily to roost in Ames, Iowa, and then left for the surrounding countryside again in the morning. Roosting has always been in the shade trees of residential areas, but apparently the trees have not been used indiscriminately. Direct observation by the writer since 1949, and comments from local citizens for conditions prior to that time, have indicated that certain trees served as roost places night after night, whereas nearby trees were not used at all.
