Survival of wood duck and mallard broods in north-central Minnesota Survival of wood duck and mallard broods in north-central Minnesota
Duckling survival in wood duck (Aix sponsa) and mallard (Anas platyrhynchos) broods was estimated from data obtained from 71 radio-marked brood hens on a study area in north-central Minnesota. Radio-marked hens produced 30 broods during the study, and 41 hens already leading broods were captured and radio-marked. Production estimates based on brood size counts were inflated by about 38...

Use of elevated nest baskets by ducks Use of elevated nest baskets by ducks
Open-top nest baskets were mounted on upright metal poles in various wetlands to assess the value of baskets as a potential technique for increasing duck nest success. Observations were made from 1966-1968 in North and South Dakota, Minnesota, and Wisconsin and were continued through 1973 in North Dakota. Baskets were used most readily in the prairie pothole region; of the 1,038 basket...

Duck plague in free-flying waterfowl observed during the Lake Andes epizootic Duck plague in free-flying waterfowl observed during the Lake Andes epizootic
The first major epizootic of duck plague in free-flying waterfowl occurred at Lake Andes, South Dakota, in January and February, 1973. Duck plague was diagnosed in black ducks, mallards, pintail-mallard hybrids, redheads, common mergansers, common golden eyes, canvasbacks, American widgeon, wood ducks, and Canada geese, indicating the general susceptibility of ducks to duck plague...

A spring aerial census of red foxes in North Dakota A spring aerial census of red foxes in North Dakota
Systematic aerial searches were flown on transects to locate adult red foxes (Vulpes vulpes), pups, and rearing dens on 559.4 km2 (six townships) in eastern North Dakota during mid-May and mid-June each year from 1969 through 1973 and during mid-April 1969 and early May 1970. The combined sightings of foxes and fox dens from the mid-May and mid-June searches were used to identify...
