Abstract

AbstractRelatively little is known about the effects of specific parasites on sexually selected behavioral traits. We subjected free‐living mountain white‐crowned sparrows (Zonotrichia leucophrys oriantha) to a playback experiment to identify the effect of hemosporidian parasites on potentially sexually selected song characteristics. We recorded song after a playback of a novel white‐crowned sparrow song, meant to simulate a territorial intrusion. Infections withLeucocytozoonorPlasmodiuminfluenced singing behavior, while infection withHaemoproteushad no detectable effect. Specifically, song consistency, as measured using a spectrogram correlation, was influenced by bothPlasmodiumandLeucocytozooninfection. Additionally, birds infected withPlasmodiumsang fewer songs following experimental playback. Thus, relatively widespread parasites, likePlasmodium, may have a strong effect on potentially sexually selected song characteristics.
