A popular swan will never fly again because generous admirers have fed it too much bread.
The bird, based in Graves Park in Sheffield, has developed a permanent condition called 'angel wing' through overeating.
This has prompted charity 'Friends of Graves Park' to urge visitors not to feed the animals bread, as it is not good for them, Yorkshire Live reports.
In a Facebook post, they said: "THIS SWAN WILL NEVER FLY AGAIN.
"This poor swan is suffering from "Angel Wing" deformity. It is not as many think, moulting. This is a permanent condition and prevents the bird from flying.
"The cause is usually down to birds being fed excess amounts of bread. It is entirely preventable. Please remember this when folk are tipping sliced loaves into the ponds."
Angel wing is a deformity that stops swans and other waterfowl from being able to fly because it permanently damages their wings.
It can appear to the untrained eye as simple moulting, but is much worse than that the Friends said.
Bread is not considered a healthy food to give to other waterfowl such as ducks as it is known to fill them up without providing them with much nutrition.
It can also pollute the water, leading to algae blooms which negatively impact the quality of the water.
Last year a spokesperson for the Royal Society for the Protection of Birds (RSPB) told MyLondon bread is not a natural source of food for water birds such as ducks and geese
They added: "Like humans, birds need a variety of food to be healthy, and bread doesn’t offer birds the nutrition they need.
"Although ducks, geese and swans are able to digest bread, it can leave them feeling full without them having gained the nutrients, vitamins and minerals they need from their natural food.
"People can feed other types of food to them which will be gratefully received. Things like peas, sweetcorn, oats and bird seed all provide more nutrition for birds, meaning they’re healthier!"
