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...

Accumulation of lead and organochlorine residues in captive American kestrels fed pine voles from apple orchards Accumulation of lead and organochlorine residues in captive American kestrels fed pine voles from apple orchards
Pine voles (Microtus pinetorum) were collected from pesticide-treated orchards in New York and fed to 3 captive American kestrels (Falco sparverius) for 60 days to evaluate potential hazards from soil-borne persistent insecticides. Three control kestrels were fed uncontaminated laboratory mice (Mus musculus). The pine voles contained an average of 38 ppm lead, 48 ppm DDE and 1.2 ppm...

Body weight and composition dynamics of fall migrating canvasbacks Body weight and composition dynamics of fall migrating canvasbacks
We studied body weights and composition of canvasbacks (Aythya valisineria) during fall migration 1975-77 on stopover sites along the upper Mississippi River near La Crosse, Wisconsin (Navigational Pools 7 and 8) and Keokuk, Iowa (Navigational Pool 19). Body weights varied (P 0.001) by age and sex without interaction. Weights varied by year (P 0.001) on Pools 7 and 8. Mean weights...

Rice available to waterfowl in harvested fields in the Sacramento Valley, California Rice available to waterfowl in harvested fields in the Sacramento Valley, California
Rice fields in the Sacramento Valley, California were sampled in 1985 and 1986 to determine the weight of rice seed remaining in the fields immediately after harvest and again after the fields were burned. No significant differences were found between years (P>0.05). The pooled mean was 388 kg/ha in harvested fields and 276 kg/ha in burned fields. These values are less than estimates...

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.

Winter raptor use of the Platte and North Platte River Valleys in south central Nebraska Winter raptor use of the Platte and North Platte River Valleys in south central Nebraska
Winter distribution and abundance of raptors were monitored within the Platte and North Platte river valleys. Data were collected along 265 km of census routes along the Platte and North Platte rivers during the winters of 1978-1979 and 1979-1980. Observations recorded during the second winter involved less observation time and were at somewhat different periods. There were 1574...
