Could it be? The claim of lead killing upland birds seemed ludicrous to me. I reported on science for years. Birds picking up lead in wide-open spaces of prairies and deserts, c'mon. Last week my nephew asked about lead in salt-water harbours where we do a lot of gunning. I replied that generations of shooting from the blind on Rum Point alone must have left a ton of lead. Could the same apply where dry-land gunning is concentrated, where habitat favours pheasant, grouse, quail etc?
