Brown-headed cowbirds in grasslands: Their habitats, hosts, and response to management Brown-headed cowbirds in grasslands: Their habitats, hosts, and response to management
The brown-headed cowbird (Molothrus ater) is an obligate brood parasite whose numbers have increased in recent decades to the potential detriment of the species that they parasitize. Thus, most management efforts focus on discouraging brown-headed cowbird parasitism or controlling brown-headed cowbird populations.

A probable extralimital postbreeding assembly of bufflehead Bucephala albeola in southcentral North Dakota, USA, 1994-2002 A probable extralimital postbreeding assembly of bufflehead Bucephala albeola in southcentral North Dakota, USA, 1994-2002
The Bufflehead Bucephala albeola predominantly in Canada and Alaska (USA). Evidence suggests that the species may have recently expanded its breeding range southward into central and south-central North Dakota. This paper presents data on observations of Buffleheads during the breeding season in Kidder County, North Dakota, 1994-2002, and discusses the possibility that the species has...
