Migrational homing by a pair of mallards
It is generally assumed that wild, North American female dabbling ducks (Anatinae: Anatini) select new mates each year and may return to the same nesting areas in consecutive years (McKinney 1964, Wildfowl 16: 93). Lincoln (1934, Bird-Banding 5: 151) first documented migrational homing in a female Mallard (Anas platyrhynchos), and Sowls (1955, Prairie ducks, Harrisburg, Pennsylvania, Stackpole Co.

Land use and prairie grouse population relationships in North Dakota
The relationship between prairie grouse and land use was studied during the period 1964-71. Prairie chickens (Tympanuchus cupido) declined from 48 males in 1964 to none in 1971. Sharp-tailed grouse (Pedioecetes phasianellus) declined from 166 males in 1964 to 57 in 1971. These declines were related to the decline in vigor and eventual loss of Soil Bank habitat on the study area. Two new courtship

A method to determine waterfowl shooting distances
Long-range shooting at ducks and geese frequently results in a high crippling loss, unretrieved birds and frustrated hunters. A principal problem has been the general inability of hunters or observers to properly judge distance of birds. This paper describes a reasonably accurate method developed to determine shooting distances to geese. Two observers utilized transit-mounted 4X hunting scopes to

Analysis of radiotracking data using digitized habitat maps
A method is described that provides a rapid and accurate analysis of habitat used by radio-equipped animals. The digitizer (basically an X-Y plotter in reverse) converts maps into digital form by describing each habitat unit as a polygon that closely approximates the actual shape of the unit. The coordinates of each polygon are then stored on magnetic tape. Habitat classification data and other in
