Abstract

Brood-parasitic screaming cowbird nestlings manipulate host parent care via a begging call structure that matches that of the host’s own young. Using playback of calls at nests, we investigated the role of begging call structure in stimulating parental provisioning by a host (baywing) to 2 brood parasites. Baywings provisioned more in response to screaming cowbird calls, which closely match those of its own young, than to shiny cowbird calls, which do not.
