Waterfowl nesting on interstate highway right-of-way in North Dakota
We studied 630 acres of roadside along 23 miles of Interstate 94 in Stutsman County, North Dakota, to assess wildlife values of highway rights-of-way. We found 422 duck nests that had an overall success of 57 percent in 1968, 1969, and 1970. Mammalian predators were responsible for 85 percent of the destroyed nests. To test the effect of mowing on duck nest initiation and success, alternate 1-mile

Classification of natural ponds and lakes in the glaciated prairie region
The wetland classification system for the United States adopted by the Bureau of Sport Fisheries and Wildlife in 1953 is described by Martin et al (1953) and by Shaw and Fredine (1956). That classification has been followed by many biologists in recent years and is especially useful in categorizing in a general manner the wetlands throughout the country over a span of years. It has become appare

Waterfowl in relation to land use and water levels on the Spring Run Area
Low water levels during critical phases of the breeding cycle appear to have caused population declines of waterfowl and other marsh birds on the Spring Run Game Management Area. Pair-counts indicated a decline from 70 pairs of waterfowl in 1965 to 2 pairs in 1968. Nest success of upland nesting blue-winged teal (Anas discors) averaged 33% and mallards (Anas platyrhyncos) averaged 23%. Blue-winged

Alula removal technique for identifying wings of released waterfowl
A technique for marking waterfowl ducklings less than 1 day old was developed to permit subsequent identification in the hand. Marking was accomplished by removing the alulae from wings of mallard (Anas platyrhynchos) ducklings with a small scissors or clipper. No differences in growth rate, behavior, or flight capability were noted between clipped and nonclipped birds. Thirty-five hundred ducklin

Waterfowl breeding habitat in agricultural and nonagricultural land in Manitoba
Waterfowl populations and habitat characteristics were examined on 33 potholes in each of two 16-square-mile study areas of agricultural and nonagricultural land in southwestern Manitoba. The agricultural land potholes, lacking in or incompletely surrounded by trees, received greater use by lesser scaup (Aythya affinis), canvasback (A. valisineria), redhead (A. americana), coot (Fulica americana),

Summer foods of lesser scaup in subarctic taiga
Reports on the food of 25 adult and 38 juvenile Aythya affinis, collected in June-Sept 1967 along the Yellowknife Highway north of Great Slave Lake. The vegetation, physiography and ponds of the area, the collecting and statistical methods are briefly described. Approx 99% of the scaup diet was animal material; juveniles in mid-summer fed on freeswimming organisms such as Chaoborinae (phantom midg
