Great Plains Research: A Journal of Natural and Social Sciences
Elk (Cervus elaphus) were historically found throughout North America but were extirpated from Nebraska and much of the Great Plains in the 1880s due to consumptive uses by settlers, miners, market hunters, and others. Elk began to reappear in Nebraska in the 1950s and 1960s, and established a stable, nonmigratory population that currently consists of seven herds and an estimated 1,400 individuals throughout western and central Nebraska. The reappearance and subsequent persistence of elk in Nebraska suggests there is adequate habitat to support a self-sustaining population. The general movement of elk eastward may lead to an eventual statewide …

A Noteworthy Record And The Breeding Distribution Of The Blue Grosbeak In North Dakota, Lawrence D. Igl
USGS Northern Prairie Wildlife Research Center
The northern limit of the blue grosbeak's (Guiraca caerulea) breeding distribution occurs in southern North Dakota. Records of the blue grosbeak in North Dakota are uncommon. Here, I report my observation of a blue grosbeak at a site where the species was recorded 25 years earlier. A summary of the species' distribution and records in North Dakota are provided.
Dramatic Increase Of Le Conte's Sparrow In Conservation Reserve Program Fields In The Northern Great Plains, Lawrence D. Igl, Douglas H. Johnson
Dramatic Increase Of Le Conte's Sparrow In Conservation Reserve Program Fields In The Northern Great Plains, Lawrence D. Igl, Douglas H. Johnson
USGS Northern Prairie Wildlife Research Center
During a continuing investigation in the northern Great Plains, we documented substantial increases of the Le Conte's Sparrow (Ammodramus Leconteii) in Conservation Reserve Program (CRP) fields in 1994 compared with 1990-93. The most dramatic increases occurred in Eddy County, North Dakota, and Sheridan County, Montana. The changes in habitat associated with the drought from 1989 to early 1993 and above-normal precipitation from mid-1993 through mid-1994 likely produced favorable breeding conditions for this species in CRP fields in 1994.
