Effects of post-impoundment shore modifications on fish populations in Missouri River reservoirs Effects of post-impoundment shore modifications on fish populations in Missouri River reservoirs

In the Missouri River main stem reservoirs in Montana, North Dakota, and South Dakota, hydrodynamic processes have decreased the lengths of shorelines and changed their configuration during the first 20 to 25 years of impoundment. Shale shores of Lakes Fort Peck, Oahe, Sharpe, and Francis Case were rapidly eroded by wave action and water level fluctuation. Banks slumped, embayments...

Early concentrations of Brown Pelicans along southern Oregon coast Early concentrations of Brown Pelicans along southern Oregon coast

The California Brown Pelican (Pelecanus occidentalis californicus), which nests in southern California and Mexico, wanders north along the coast after the breeding season, sometimes as far as southern British Columbia (A.O.U. 1957). Anderson and Anderson (1976) and Ainley (1972) report that Mexico-originating pelicans disperse north in late summer and fall, increasing California coastal...

A variable circular-plot method for estimated bird numbers A variable circular-plot method for estimated bird numbers

A bird census method is presented that is designed for tall, structurally complex vegetation types, and rugged terrain. With this method the observer counts all birds seen or heard around a station, and estimates the horizontal distance from the station to each bird. Count periods at stations vary according to the avian community and structural complexity of the vegetation. The density...

Factors affecting waterfowl breeding density and productivity estimates in the Northeast Factors affecting waterfowl breeding density and productivity estimates in the Northeast

During 1977-79, information useful for making breeding pair and brood surveys was obtained while studying black duck (Anas rubripes) habitat selection and productivity in south-central Maine. Surveys should be initiated in relation to sunrise and sunset time. Morning versus evening counts, familiarity with the survey area, wetland dynamics of the study area, wetland surface water area...
