Survival of northern bobwhites in Georgia: Cropland use and pesticides Survival of northern bobwhites in Georgia: Cropland use and pesticides
At the end of 18 weeks during spring and summer in 1986 and 1987, survival was 0.5339 and 0.3709 respectively. Repeated organophosphorus insecticide sprays to crops in 1987 may have significantly reduced survival of bobwhites beyond that seen in 1986 when few pesticides were applied. Cropland use was high; birds were found less than 50% of the time in or less than 100 meters of field...

Small mammal populations at hazardous waste disposal sites near Houston, Texas, USA Small mammal populations at hazardous waste disposal sites near Houston, Texas, USA
Small mammals were trapped, tagged and recaptured in 0·45 ha plots at six hazardous industrial waste disposal sites to determine if populations, body mass and age structures were different from paired control site plots. Low numbers of six species of small mammals were captured on industrial waste sites or control sites. Only populations of hispid cotton rats at industrial waste sites...

Northern bobwhite, gray partridge, and ring-necked pheasant population trends (1966-1988) from the North American Breeding Bird Survey Northern bobwhite, gray partridge, and ring-necked pheasant population trends (1966-1988) from the North American Breeding Bird Survey
We use North American Breeding Bird Survey data to estimate population trends for 1966-1988 for northern bobwhite (Colinus virginianus), ring-necked pheasant (Phasianus colchicus), and gray partridge (Perdix perdix). Bobwhite populations have undergone widespread declines, pheasant have undergone major declines in eastern North America with mixed trends elsewhere, gray partridge have...

Body mass and lipid content of shorebirds overwintering on the south Texas coast Body mass and lipid content of shorebirds overwintering on the south Texas coast
Three species of shorebirds were collected at bimonthly intervals in 1979-1980, from the time of their arrival in early autumn to mid-February, on the south Texas coast. Female Long-billed Dowitchers (Limnodromus scolopaceus) and Western Sandpipers (Calidris mauri) were heavier (P 0.05) than males, but the reverse was true for American Avocets (Recurvirostra americana). Lipid content...

Intersexual and temporal variation in foraging ecology of prothonotary warblers during the breeding season Intersexual and temporal variation in foraging ecology of prothonotary warblers during the breeding season
We studied foraging ecology of Prothonotary Warblers (Protonotaria citrea) over four breeding seasons to determine if this species exhibited sex-specific or temporal variation in foraging behavior. Significant differences between sexes during the prenestling period were found for foraging height and substrate height (foraging method, plant species/substrate, perch diameter, horizontal...
