The need for accuracy in modelling: An example The need for accuracy in modelling: An example
The need for accurate information in modelling depends on the objectives of the effort, but trustworthy data are essential for a model intended for use in the management of natural resources. This point is illustrated by referring to a recently published model of canvasback ducks. We demonstrate that several key assumptions are not supported by biological evidence, and that inferences...

Fat deposition and usage by arctic-nesting sandhill cranes during spring Fat deposition and usage by arctic-nesting sandhill cranes during spring
Body weight, fat, and protein levels of arctic-nesting Sandhill Cranes (Grus canadensis) were measured at several locations during spring migration and on the breeding grounds. Body weights of adult males and females increased by about 34% (1,129 g) and 30% (953 g) from early March at the Platte River to late April at Last Mountain Lake, Saskatchewan; average fat content increased from...

Mallard recruitment in the agricultural environment of North Dakota Mallard recruitment in the agricultural environment of North Dakota
Recruitment of a mallard (Anas platyrhynchos) population was assessed on a 10,041-km2 study area in central North Dakota during 1977-80. We equipped 338 hens with radio transmitters and monitored them during the breeding season. Two hundred thirty-five of these hens furnished data reported here. Habitat use, nest site selection, fate of nests, and the rate of renesting were measured...

Organochlorine contaminants in California waterfowl Organochlorine contaminants in California waterfowl
Concern has been expressed that the extensive use of organochlorine pesticides in California may be exposing waterfowl to hazardous contaminant levels. The objectives of our study were to: (1) determine concentrations of organochlorines in northern pintails (Anas acuta) from five important waterfowl wintering areas in California; (2) compare concentrations of organochlorines in selected...

Larval dermestid beetles feeding on nestling snail kites, wood storks, and great blue herons Larval dermestid beetles feeding on nestling snail kites, wood storks, and great blue herons
In recent years abdominal lesions attributable to larval dermestid beetles (Dermestes nidum) have appeared in nestling Snail (Everglade) Kites (Rostrhamus sociabilis), Wood Storks (Mycteria americana), and Great Blue Herons (Ardea herodias). Although it appears that most nestlings affected have survived, the degree of threat posed by dermestid larvae to various avian species is as yet...
