Abstract

For a number of years, during the summer and fall months, thousands of bronzed grackles, Quiscalus quiscula, and starlings, Sturnus vulgaris, have come from the surrounding countryside each evening to roost in the shade trees in residential areas of Ames, Iowa. Regularly associated with them have been lesser numbers of cowbirds, Molothrus ater, and robins, Turdus migratorius. Beginning with preliminary observations in 1949, the roosting flights of these birds, as well as the features of their roost, were kept under observation until late 1952. Results of the observations on the roost have been given in Bliese and Hendrickson (1952), and Bliese (1953a and b, 1954a and b). This paper concerns the roosting flights only, and confines itself to those of the grackles and starlings.
