There is little existing evidence to suggest that waterfowl other than swans are affected by ingesting lead from fishing weights.
I also understand that it applies only to swans on open water.
However, the main source of damage to swans and cygnets is poisoning caused by lead weights discarded, or lost, by fishermen.
Lead weights are not only the most common but the most avoidable cause of death among swans.
Why do we have to keep her prerogative right for swans?
I made the suggestion that in the winter, if serious disturbance were caused to the swans, the targets could be put out at sea.
