Tidal marsh loss to anthropogenic environmental impacts and climate change, particularly sea level rise, has and will continue to cause declines in tidal marsh bird populations. Distribution patterns of tidal marsh birds are generally known, yet we l

Costs of multiple parasitism for an avian brood parasite, the Brown-headed Cowbird (Molothrus ater)

Autor: Nancy E. Mathews, David R. Curson, Christopher B. Goguen

Publikováno v: Canadian Journal of Zoology. 89:1237-1248

The Brown-headed Cowbird (Molothrus ater (Boddaert, 1783)) is a generalist brood parasite that often lays into nests that contain conspecific eggs. Although it has often been assumed that this multiple parasitism reduces Cowbird sur- vival, this has

Effects of Parasitism by Brown-Headed Cowbirds (MOLOTHRUS ATER) on Reproductive Success of Three Frequent Hosts in New Mexico

Autor: David R. Curson, Christopher B. Goguen, Nancy E. Mathews

Publikováno v: The Southwestern Naturalist. 54:58-67

We studied effects of parasitism by brown-headed cowbirds (Molothrus ater) on three frequent hosts from a pinyon-juniper (Pinus-Juniperus) community in New Mexico. During 1993–1999 and 2001–2002, we measured frequencies of parasitism and examined

Behavioral Ecology of the Brown-Headed Cowbird (Molothrus ater) in a Bison-Grazed Landscape in New Mexico

Autor: David R. Curson, Nancy E. Mathews, Christopher B. Goguen

Publikováno v: Ornithological Monographs. :71-83

Brown-headed cowbirds (Molothrus ater; hereafter "cowbirds") often forage with grazing ungulates. Although domestic livestock have largely replaced American bison (Bos bison) as the cowbird's foraging associate, recent restoration of bison to their f
