Wetland bird seasonal abundance and habitat use at Lake Earl and Lake Talawa, California Wetland bird seasonal abundance and habitat use at Lake Earl and Lake Talawa, California
A study of wetland bird composition, seasonal abundance, and habitat use was conducted on Lake Earl and Lake Talawa in Del Norte County, California from July 1974 through February 1976. Ninety-five species were recorded. Most birds occurred from October to December and during March and April. Diving ducks occurred primarily during fall and winter and were more abundant than surface...

Carbonate deposition on tail feathers of ruddy ducks using evaporation ponds Carbonate deposition on tail feathers of ruddy ducks using evaporation ponds
Substantial carbonate deposits were observed on rectrices of Ruddy Ducks (Oxyura jamaicensis) collected during 1982-1984 on evaporation ponds in the San Joaquin Valley, California. Carbonate deposits were composed of about 75% aragonite and 25% calcite, both polymorphous forms of CaCO3. Significantly more carbonate deposits were observed on Ruddy Ducks as length of exposure to...

Vegetation of wetlands of the prairie pothole region Vegetation of wetlands of the prairie pothole region
Five themes dominate the literature dealing with the vegetation of palustrine and lacustrine wetlands of the prairie pothole region: environmental conditions (water or moisture regime, salinity), agricultural disturbances (draining, grazing, burning, sedimentation, etc.), vegetation dynamics, zonation patterns, and classification of the wetlands.The flora of a prairie wetland is a...

Estimating carcass fat and protein in northern pintails during the nonbreeding season Estimating carcass fat and protein in northern pintails during the nonbreeding season
I used northern pintails (Anas acuta) collected from August through March 1979-82 in the Sacramento Valley, California to derive equations to predict ether-extracted carcass fat, carcass protein, and skeletal lean dry weight. Ether-extracted carcass fat was best predicted by total fat depot weight (wet skin, abdominal fat, and intestinal fat) (r2 = 0.94) and estimates based on carcass...

Importance of individual species of predators on nesting success of ducks in the Canadian prairie pothole region Importance of individual species of predators on nesting success of ducks in the Canadian prairie pothole region
We followed 3094 upland nests of several species of ducks. Clutches in most nests were lost to predation. We related daily nest predation rates to indices of activity of eight egg-eating predators, precipitation during the nesting season, and measures of wetland conditions. Activity indices of red fox (Vulpes vulpes), striped skunk (Mephitis mephitis), and raccoon (Procyon lotor)...

Effects of fire in the Northern Great Plains Effects of fire in the Northern Great Plains
This publication is a review of selected literature about prescribed burning in the Northern Great Plains (NGP) for management of wildlife. It also will be useful to other resource managers and researchers and to persons interested in the NGP. It is more 'descriptive' than 'interpretative.'The publication is a joint effort of the South Dakota State Cooperative Fish and Wildlife Research...

Least squares estimation of avian molt rates Least squares estimation of avian molt rates
A straightforward least squares method of estimating the rate at which birds molt feathers is presented, suitable for birds captured more than once during the period of molt. The date of molt onset can also be estimated. The method is applied to male and female mourning doves.
