Hunter ‘crippling losses’, or unretrieved kill, probably range from 20% to 40% of all ducks hit by gunfire. However, this major mortality factor in duck populations has been largely ignored by waterfowl policymakers and managers. An economic analysis of ‘crippling losses’ for prairie Canada and the USA was conducted, based on 1992 harvest statistics. The analysis is based on current levels of spending on habitat programmes designed to bolster declining North American duck populations, with reference to the North American Waterfowl Management Plan.
