Differential parasitism of least flycatchers and yellow warblers by the brown-headed cowbird

Abstract

Brown-headed cowbirds (Molothrus ater) parasitized yellow warblers (Dendroica petechia) six times more frequently than least flycatchers (Empidonax minimus) nesting in the same riparian habitat in southern Manitoba.
