Abstract

A survey of literature, egg collections and field data produced a list of 60 species that have served as hosts of the brood parasitic Brown-headed Cowbird in Iowa. About 52 of these species are known to have reared cowbird young. In Iowa, those species most commonly parasitized - in absolute numbers - include Red-winged Blackbirds, Dickcissels, Common Yellowthroats and Song Sparrows. An additional 36 species are listed which nest in Iowa but have not yet been recorded as cowbird hosts in the state even though they have served as cowbird hosts elsewhere.
