Swans and litter

Today i have been to pennington flash where i was recording swan for the Northwest swan study. There was a swan with a blue ring on that had just come round from where the fishermen where fishing she cam to the side of the banking to where i was feeding the ducks and swans. it apperad the swan had a big brown stain down it back as i went to have a look it was coffee still hot. the fishermen had thrown hot coffee of the swan to try and move the swan on so she would not disturb the fish and the fishermen. i thought to my self how cruel can someone be to do something like that to a really amazing creature i think theses men and youths who did this are really sick and something ought to be done about it.
Swan's and fishing line.
Hooks caught in the mouth also bleed profusely and cause a fair a mount of bruising but recovery is generally quick after removal. Fishing line is often found caught under the lower beak and can be found by running your finger nail under the birds chin. This should be cut off and gently removed. The line may have embedded itself deeply and the wound may need debrided and cleaned. Unless very severe these problems clear up well.
Line may also get caught round the tongue with the trailing ends being swallowed these can some times be gently pulled up with the bird conscious but generally it is easier if they are anaesthetised. This is also the case for hooks caught at the very back of the mouth adjacent to the top of the oesophagus,(an area we call `the bastard'). It is incredibly difficult to reach from either end and has to be treated on a very individual basis. Hooks caught in the oesophagus show a variety of symptoms ranging from, a small mobile lump, soft tissue swelling and huge bulging necks. A hook which can be felt externally and seen on x-ray may well have been walled off and already disintegrating. Large oesophageal tears may not show a hook on x-ray, the kind fisherman may have already retrieved that hence the large tear.
please don't leave fishing line on the side of the banking take it home and put all rubbish in the bin thanks
