Nebraska sits at the nexus of continental bird migration and serves as a home?either permanently or seasonally?for nearly 450 species. Major migratory routes pass through the state, creating numerous opportunities to observe the great variety of North American bird species. The annual crane migrations in spring are legendary, and other key events include winter concentrations of bald eagles, flocks of up to thirty thousand grebes, mergansers, and gulls at Lake McConaughy in late fall, and incredible concentrations of waterfowl in the Rainwater Basin in early spring.øBirds of Nebraska captures the variety of Nebraska's ornithological possibilities in a style useful to hobbyists and professionals alike. For the first time in Nebraska ornithology, the authors have provided an exhaustive summary of state bird records compiled into concise but readable accounts of all species of birds reported in the state. This work covers taxonomy, early and late migration dates, high counts, nesting areas, and likely viewing locations.
The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains.
