Distribution An D Dispersion Patterns Of San Dhill Crane Flocks In The Platte River Valley, Brian Lorenz, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
We evaluated sandhill crane (Grus canadensis) flock distribution and dispersion patterns along the Platte River Valley, Nebraska, in 2002-2003. The objectives were to: (a) determine the overall distribution and relationship between roosting and foraging flock numbers by bridge segments, (b) evaluate flocking characteristics in relation to abundance of cranes in different bridge segments and total abundance, and (c) correlate dispersion patterns and habitat use to period of migration, roost locations, and habitat types. Preliminary predictions included: foraging flock dispersions would be correlated with roost locations; greater numbers and larger flock sizes will be present in bridge segments with …

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 …
