Nongame bird communities on managed grasslands in North Dakota Nongame bird communities on managed grasslands in North Dakota
Grazed native prairie, unmanipulated native prairie, and planted alfalfa-wheatgrass habitats each supported prairie bird species unique to that habitat type. Comparisons of the three habitats, using community coefficients and overlap indices, showed that grazed and alfalfa-wheatgrass habitats supported the most dissimilar or unique bird communities. All three habitat types, or habitats...

Fall and winter foods of northern pintails in the Sacramento Valley, California Fall and winter foods of northern pintails in the Sacramento Valley, California
Food habits of northern pintails (Anas acuta) were investigated on 3 national wildlife refuges in the western portion of the Sacramento Valley, California, from August to March 1979-82. Pintails consumed 97% (aggregate % dry wt) plant food during diurnal foraging on national wildlife refuge rice, summer-irrigated, and summer-dry habitats from August through January. Invertebrate use...

Composition and stability of coyote families and territories in North Dakota Composition and stability of coyote families and territories in North Dakota
Coyote (Canis latrans) families studied in North Dakota during 1976 to 1978 contained three or more adults during the spring-summer season, and they occupied large contiguous, non-overlapping territories. Coyote territories averaged 61 km2 during the spring-summer season and 30 km2 during fall-winter season. Three of four families occupied territories that were similar in size for two...

Feeding ecology of northern pintails and green-winged teal wintering in California Feeding ecology of northern pintails and green-winged teal wintering in California
The feeding ecology of northern pintails (Anas acuta) and green-winged teal (A. crecca) was examined from October through February 1979-81 in 4 major seasonal marsh types in the Central Valley, California. The esophagi of 262 pintails contained 72.3% plant seeds and 27.7% animal matter. The esophagi of 173 green-winged teal contained 62.3% plant seeds and 37.6% animal matter. Swamp...

Breeding birds and vegetation structure in western North Dakota wooded draws Breeding birds and vegetation structure in western North Dakota wooded draws
Populations and distribution of breeding birds occupying wooded draws were studied in a five-county region of western North Dakota during June 1982. Wooded draw vegetation was dominated by green ash, which occurred in 96% of the draws sampled. Chokecherry and juneberry were the most frequent shrub species. I recorded 49 bird species in the 30 draws censused. Rufous-sided towhee, brown...

Responses of three prairie ground squirrel species, Spermophilus franklinii, S. richardsonii, and S. tridecemlineatus, to duck eggs Responses of three prairie ground squirrel species, Spermophilus franklinii, S. richardsonii, and S. tridecemlineatus, to duck eggs
Franklin's Ground Squirrels (Spermophilus franklinii) preyed on eggs in 29 of 30 tests in which they were exposed to two Mallard (Anas platyrhynchos) or two Blue-winged Teal (A. discors) eggs and their discovery of eggs was confirmed. No Richardson's (S. richardsonii) or Thirteen-lined (S. tridecemlineatus) ground squirrels preyed on eggs in 104 and 54 similar tests, respectively...

Hydrology and chemistry of selected prairie wetlands in the Cottonwood Lake area, Stutsman County, North Dakota, 1979-82 Hydrology and chemistry of selected prairie wetlands in the Cottonwood Lake area, Stutsman County, North Dakota, 1979-82
The relation of hydrologic setting and temporal variability in hydrology to nutrient content and geochemical characteristics of a group of prairie wetlands and adjacent ground water was studied during the period 1979-82. Although data were collected from many wetlands and wells at the study site, emphasis in this report primarily is on four wetlands two seasonal and two semipermanent and...

Northern pintail body condition during wet and dry winters in the Sacramento Valley, California Northern pintail body condition during wet and dry winters in the Sacramento Valley, California
Body weights and carcass composition of male and female adult northern pintails (Anas acuta) were investigated in the Sacramento Valley, California, from August to March 1979-82. Pintails were lightweight, lean, and had reduced breast, leg, and heart muscles during August-September. Ducks steadily gained weight after arrival; and body, carcass (body wt minus feathers and gastrointestinal...
