Abstract
The operation of decoy traps at The North Central Farm, Vickery, Ohio, the Ottawa-Crane Creek-McGee Marsh Area, and on the Bass Islands in Lake Erie, has permitted the banding of thousands of Red-winged Blackbirds (Agelaius phoeniceus), Common Grackles (Quiscalus quiscala), Brown-headed Cowbirds (Molothrus ater), and Starlings (Sturnus vulgaris). The repeats and returns of these banded birds justify inferences concerning the sex and age ratios in the populations and the stability of the populations, as well as indicating the seasonal migrations and movements of the populations.
