Abstract

I report the first observation of conspecific brood parasitism in the Dickcissel (Spiza americana). I monitored 302 nests during a study of the interactions between parasitic Brown-headed Cowbirds (Molothrus ater) and Dickcissels. This and a possible second case of conspecific brood parasitism may have resulted from females laying in nests after their original nests were destroyed in nearby hayfields.
