Brown-Headed Cowbirds

1998
Abstract Most avian brood parasites use more than one host species (Friedmann 1948, 1960, 1963; Friedmann et al. 1977). Brown-headed and shiny cowbirds (Molothrus ater and M. bonariensis) are extreme generalists among brood parasites, and use a variety of hosts in each habitat and geographic area (Friedmann 1963; Friedmann et al.

Brown-Headed Cowbird Behavior and Movements in Relation to Livestock Grazing

Ecological Applications, 2001
The Brown-headed Cowbird (Molothrus ater) is a widespread brood parasite which often engages in a commensalistic feeding relationship with domestic livestock. We studied the behavior of female cowbirds breeding in pinyon–juniper woodlands in New Mexico, USA, on two adjacent sites, one an active cattle ranch, and the other a site that was not grazed by ...

The Song Sparrow and the Brown-Headed Cowbird

2006
Abstract The Life History of the Cowbird and Other Brood Parasites The brown-headed cowbird is one of 100 species of obligate brood parasitic birds worldwide (Davies 2000; Lowther 1993). These birds lay all their eggs in the nests of other “host” species, which then incubate the parasite eggs and rear the resulting young (Rothstein ...

Ecology of parasitism of Brown-headed Cowbirds by haematozoa

Canadian Journal of Zoology, 1992
We quantified haematozoa infections in 964 Brown-headed Cowbirds (Molothrus ater) sampled over three summers in eastern Ontario. Our objective was to use the cowbird–haematozoa system to assess practical and theoretical aspects of testing Hamilton and Zuk's parasite hypothesis of sexual selection.
