Book Description
Poisoning of North American waterfowl resulting from the ingestion of lead shot by ducks, geese, and swans causes an estimated annual mortality of 2% to 3% of the population. To alleviate this problem the search for a suitable substitute for lead has been underway since the early 1950's. Proposed substitutes for lead shot were evaluated in a series of acut toxicity tests with pen-reared mallards. Most candidate materials were as toxic to ducks as commercial lead shot. Coating or alloying lead with other materials only delayed mortality among dosed ducks.

The ingestion of one lead shot, size 4, by each of 80 pen - reared mallards caused an average 19% mortality.
