A sample of 591 American Black Duck, Anas rubripes, gizzards from Nova Scotia (N.S.) included 4.6% that contained ingested lead shot.Among those, 7.1% of 198 gizzards from Cumberland County contained shot.In Prince Edward Island (P.E.I.), 7.1% of 224 Black Duck gizzards contained ingested shot, including 11.1% of 63 from Queens Co.In N.S., 14.3% of 91 Ring-necked Ducks, Aythya collaris, contained ingested shot, including 13.0% of 77 from Cumberland Co.In P.E.L., 52.8% of 53 Ring-necked Duck gizzards contained ingested shot, all but three of these from Pisquid Pond, Kings Co.In certain areas, these proportions exceeded (a= 0.05) the 5% maximum suggested by the Canadian Wildlife Service (CWS) as requiring further study, but they rarely exceeded (a= 0.05) the 10% maximum suggested as requiring a lead shot ban.Nevertheless, lead shot ingestion by N.S. and P.E.I. waterfowl is causing mortality.Our data suggested that non-toxic shot zones for the hunting of waterfowl be established on the following areas: East Amherst Marsh and Wallace Bay National Wildlife Area, Cumberland Co., N.S.; Pisquid Pond, Kings Co., P.E.I.; and wetlands in
