Our local parks have slowly been putting up signs that suggest that the wild fowl are actively harmed by feeding them bread.
It means that feeding them is no longer a cheap activity.
However the Swan Sanctuary have put out a statement to say this isn't true, and "We strongly disagree with the idea that the campaign will improve the health of swans and other waterfowl. In fact, we believe it could actually have a detrimental effect on the waterfowl. The Sanctuary has evidence that when people stop feeding bread, to the birds, they quite often stop completely rather than substitute the bread with an alternative."
