Low success in shiny cowbird chicks parasitizing rufous-bellied thrushes: chick-chick competition or parental discrimination?
Article Abstract:
Research is presented concerning the significant reduction which was observed in the feeding of parasitizing chicks of the shiny cowbird due to parental discrimination by rufous-bellied thrushes.

Selfish begging by screaming cowbirds, a mimetic brood parasite of the bay-winged cowbird
Article Abstract:
Research describing the comparative begging behavior of screaming and bay winged cowbird nestlings is presented. It is shown that parasitic nestlings beg more intensively for the same degree of hunger than the host nestlings.

Why brown-headed cowbirds do not influence red-winged blackbird parent behaviour
Article Abstract:
The effect of brood parasitism on host parent and offspring behaviour in younger and older broods is compared. The results indicate that the presence of the cowbird in the nest affected neither the latency nor duration of host nestling begging, but stimulated more frequent begging by red-winged blackbird nestlings following food distribution.
