Population recovery of the Whooping Crane with emphasis on reintroduction efforts: Past and future Population recovery of the Whooping Crane with emphasis on reintroduction efforts: Past and future
The U.S. Fish and Wildlife Service (USFWS) began building a captive whooping crane (Grus americana) colony at Patuxent Wildlife Research Center (Patuxent), Maryland, in 1966. From 1976 to 1984, 73 eggs from this colony and 216 eggs from Wood Buffalo National Park (Wood Buffalo), Canada, nests were placed in sandhill crane (G. canadensis) nests at Grays Lake National Wildlife Refuge...

Survival of cackling Canada geese, 1982-1988 Survival of cackling Canada geese, 1982-1988
We estimated seasonal and annual survival rates of cackling Canada geese (Branta canadensis minima) for the period 1982-1989 to identify periods of high mortality and assess effects of harvest management decisions. We tested hypotheses about age- and sex specific variation in survival, seasonal variation in survival rates, and variation in survival between years in which hunting seasons...

Lead toxicosis in tundra swans near a mining and smelting complex in northern Idaho Lead toxicosis in tundra swans near a mining and smelting complex in northern Idaho
Die-offs of waterfowl have occurred in the Coeur d'Alene River system in northern Idaho since at least the early 1900's. We investigated causes of mortality and lead and cadmium contamination of 46 tundra swans (Cygnus columbianus) from 1987 to 1989; an additional 22 swans found dead in 1990 were not examined. We necropsied 43 of the 46 birds found from 1987 to 1989; 38 of these were...

Survival of postfledging female American black ducks Survival of postfledging female American black ducks
We equipped 106 hatching-year (HY), female, black ducks (Anas rubripes) with transmitters during 1985-87 and monitored survival from late August to mid-December on a lightly hunted area on the Maine-New Brunswick border. The 1985-87 estimate of survival (hunting losses included) was 0.593, and when losses from hunting were censored it was 0.694. Survival in August-September was 0.987; by...

Science, population ecology, and the management of the American black duck Science, population ecology, and the management of the American black duck
This essay deals with the relevance of some of the ideas of Romesburg (1981) to population ecology and management of the American black duck (Anas rubripes). Most investigations dealing with the effects of hunting regulations on black duck populations have used the hypothetico-deductive (H-D) approach of specifying a priori hypotheses and associated deduced predictions. These...

Ectoparasitism and the role of green nesting material in the European starling Ectoparasitism and the role of green nesting material in the European starling
The use of green nesting material is widespread among birds. Recent evidence suggests that birds use secondary chemicals contained in green plants to control ectoparasites. We manipulated green nesting material and ectoparasites of European starlings (Sturnus vulgaris) to test two hypotheses: (1) ectoparasites adversely affect prefledging survival and morphometrics or postfledging...

Lead accumulation and osprey production near a mining site on the Coeur d'Alene River, Idaho Lead accumulation and osprey production near a mining site on the Coeur d'Alene River, Idaho
Mining and smelting at Kellogg-Smelterville, Idaho, resulted in high concentrations of lead in Coeur d'Alene (CDA) River sediments 15–65 km downstream, where ospreys (Pandion haliaetus) nested. Adult and nestling ospreys living along the CDA River had significantly higher blood lead concentrations than those at Lake Coeur d'Alene (intermediate area) or Pend Oreille and Flathead Lakes...
