Tundra swan habitat preferences during migration in North Dakota
I studied tundra swan (Cygnus columbianus columbianus) habitat preference in North Dakota during autumn migration, 1988-89. Many thousand tundra swans stop in the Prairie Pothole region during autumn migration, but swan resource use has not been quantified. I examined habitat preference in relation to an index of sago pondweed (Potamogeton pectinatus) presence, extent of open water, and wetland si

Age-related reproduction in striped skunks (Mephitis mephitis) in the upper Midwest
Reproductive data from the upper Midwest are meager for the striped skunk (Mephitis mephitis), a common North American carnivore. We provide data on some age-related reproductive attributes of 178 female striped skunks collected at 19 sites in eastcentral North Dakota and westcentral Minnesota in 1979–1981 and 1987–1991. Seventy-four percent of the females were 1 year old; 95% were pregnant or par

Variation in body mass of wild canvasback and redhead ducklings
We assessed variation in body mass of ducklings in single- and mixed-species broods of wild Canvasbacks (Aythya valisineria) and Redheads (Aythya americana) 20-50 days old. Body mass of canvasback ducklings was not affected by year and season (early vs. late hatch date) despite changes in water conditions. Mean body mass of male and female Canvasbacks did not differ in Class IIA but did differ in

Waterfowl botulism--a brief summary
Botulism is a food poisoning caused by the ingestion of the toxin produced by the bacterium Clostridium botulinum of any of six strains, designated A through F. The disease, as it occurs in epidemic proportion in wild birds, is most commonly of the C type, although outbreaks caused by type E botulism have been observed on the Great Lakes.
C. botulinum is a widely distributed anaerobic bacterium wh

Locating, constructing, and managing islands for nesting waterfowl
The purpose of this extension bulletin is to assist public and private managers in locating, constructing, and managing islands to enhance nest success of waterfowl. The information is from studies by the Northern Prairie Wildlife Research Center, Jamestown, North Dakota, and information collected by biologists working at sites throughout the northern hemisphere.

Locating and managing peninsulas for nesting ducks
The purpose of this extension bulletin is to guide the management of nesting ducks on peninsulas on public and private lands. Managing peninsulas for ducks is a relatively new strategy that was developed in the grassland region of western North America. Information contained in this bulletin is primarily from studies conducted by biologists working at the Northern Prairie Wildlife Research Center.

Conservation reserve program: benefit for grassland birds in the northern plains
During the past few decades numbers of some species of upland-nesting birds in North America have declined. Duck species such as mallard (Anas platyrhynchos), northern pintail (A. acuta) and blue-winged teal (A. discors) have declined since the early 1970s and have remained low since 1985 (Caithamer et al. 1993). Some grassland-dependent nonwaterfowl species also have declined since 1966, as indic
