Waterfowl damage to Canadian grain : current problem and research needs / by Lawson G. Sugden.: CW69-1/24E-PDF
"Waterfowl damage to crops in Alberta, Saskatchewan and Manitoba first became severe in the 1940's when the practice of swathing grain became prevalent. Mallards (Anas platyrhynchos) cause the most damage, which is sustained primarily by barley and wheat. Loss of grain is most severe in wet autumns that delay the harvest and tends to be chronic near large wetlands that harbour ducks in autumn"--Abstract.
