The Screaming Cowbird is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The Screaming Cowbird (Molothrus rufoaxillaris) is a species of bird in the Icteridae family. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Its natural habitats are pastureland and heavily degraded former forest. References - * BirdLife International 2004. Molothrus rufoaxillaris. 2006 IUCN Red List of Threatened Species.

Screaming Cowbird (Molothrus rufoaxillaris), a brood parasite that almost exclusively parasitizes Bay-winged Cowbirds. Friedmann (1929) considered these two species closely related, but this is not the case (Lanyon 1992); regardless of phylogenetic relationships, these two species are tightly bound together in their reproductive biology. The host-parasitic relationship between Bay-winged and Screaming cowbirds was first realized on 12 April 1873 by W. H. More

SCREAMING COWBIRD Molothrus rufoaxillaris In keeping with other cowbirds the Screaming is a nest parasite, though, in contrast to the extremely similar Shiny Cowbird who lays its eggs anywhere, the Screaming is a little more focused in its target - namely the Greyish Baywing. Juvenile Screamings bear a remarkable resemblance to both adult and juvenile Baywings, the unlucky parents being scammed into raising somebody else More

nestling Screaming Cowbird failed within 2 days Failed within 2 days were statistically indistinguishable (P > 0.5 for all comparisons among immaculate and spotted Shiny Cowbird eggs and Screaming Cowbird eggs; Fisher's exact test, Siegel 1956). Further- more, the assignment of species as accepters or rejecters (Table 1) agrees with Fraga (1978, 1980, 1983b, 1985) for 11 common species, including all rejecters. Observations of natural parasitism agree (Mason 1986). Lack of competition from the Screaming Cow- bird. More
