Conditioned aversion of aluminum sulfate in black ducks Conditioned aversion of aluminum sulfate in black ducks
Three experiments were conducted to determine if reduced consumption of foods with elevated Al levels by black ducks (Anas rubripes) was due to taste aversion, conditioned taste aversion or malaise. Black ducks preferred a diet with 1,000 ppm Al over a control diet but ate less of a diet with 5,000 ppm Al. Prior experience with the high Al diet enhanced preference for the control diet...

Home range and movements of postfledging American black ducks in eastern Maine Home range and movements of postfledging American black ducks in eastern Maine
We monitored the movements of 97 female and 15 male juvenile American black ducks (Anas rubripes) in the vicinity of Moosehorn National Wildlife Refuge in eastern Maine and southwestern New Brunswick from September through mid- December, 1985-1987.. Movements were described by estimating home ranges and radial movements from the primary roost marsh. Overall home range sizes averaged 4987...

Topics in route-regression analysis Topics in route-regression analysis
The route-regression method has been used in recent years to analyze data from roadside surveys. With this method, a population trend is estimated for each route in a region, then regional trends are estimated as a weighted mean of the individual route trends. This method can accurately incorporate data that is unbalanced by changes in years surveyed and observer differences. We suggest...

Foraging flights of the white-tailed tropicbird (Phaethon lepturus): Radiotracking and doubly-labelled water Foraging flights of the white-tailed tropicbird (Phaethon lepturus): Radiotracking and doubly-labelled water
Radiotracking transmitters were fitted to White-tailed Tropicbirds nesting at Culebra, Puerto Rico. Foragers were located by light aircraft out to 89 km SSW of the nesting colony, over a deep-water foraging area south of Vieques Island, Puerto Rico and west of St Croix, U. S. Virgin Islands. Two birds were followed out to 176 km NNW from the colony, over the Puerto Rico Trench, but these...

Eggshell thinning and contaminant levels in bald eagle eggs from Arizona, 1977 to 1985 Eggshell thinning and contaminant levels in bald eagle eggs from Arizona, 1977 to 1985
The mean eggshell thickness of 11 eggs of bald eagles (Haliaeetus leuccocephalus) and 21 samples of eggshell fragments (n = 32) collected from 14 nests in Arizona during 1977 to 1985 was 0.539 mm, 8.8% thinner than the pre-1947 (pre-DDT) mean for eggs from southern California and Baja California, Mexico. Eleven eggs analyzed for contaminants contained slightly elevated concentrations of...

Effects of organophosphorus insecticides on sage grouse in southeastern Idaho Effects of organophosphorus insecticides on sage grouse in southeastern Idaho
Die-offs of sage grouse (Centrocercus urophasianus) were verified in southeastern Idaho in 1981. We captured 82 apparently healthy grouse to quantify the effects of organophosphorus insecticides (OP's) and other pesticides on sage grouse in sagebrush (Artemisia spp.) bordering agricultural lands in July 1985 and 1986. Grouse were fitted with radio collars and tracked through part of each...
