Recruitment failure in American avocets and black-necked stilts nesting at Kesterson Reservoir, California, 1984-1985 Recruitment failure in American avocets and black-necked stilts nesting at Kesterson Reservoir, California, 1984-1985

We evaluated recruitment by American Avocets (Recurvirostra americana) and Black-necked Stilts (Himantopus mexicanus) in 1984 and 1985 at the selenium-contaminated Kesterson Reservoir and at a nearby reference site, the Volta Wildlife Area, both in western Merced County, California. Nests were monitored to determine their outcomes, including hatching success, and broods were censused...

Movements, home range, and territories of male sea otters off central California Movements, home range, and territories of male sea otters off central California

Sixty male sea otters (Enhydra lutris) were tagged on the rear flippers with colored tags. Of these, 46 (77%) were resighted. Movements of 127 km were documented for adults and 187 km for subadults. Adults maintained breeding territories that averaged 40.3 ha (n= 10, SE = 4.0). They returned to the same territory seasonally for up to seven consecutive years. Territorial males moved from...

Contaminants in foods of aquatic birds at Kesterson Reservoir, California, 1985 Contaminants in foods of aquatic birds at Kesterson Reservoir, California, 1985

Plants, aquatic insects, and mosquitofish (Gambusia affinis) were collected from Kesterson Reservoir, Merced County, California, and a nearby reference site (Volta Wildlife Area) to compare concentrations of three contaminants found in 1985 with those reported in 1983 and 1984. Mean selenium concentrations in food-chain organisms from sites at Kesterson in 1985 ranged from 26.0 μg/g (dry...
