This happened in Stratford, England. The poor man was so hungry that he swallowed the bait fish. Due to the rapid intervention of the people managed to save a swan.
The photo shows how a bird vet calms and tries to determine the place where the fish hook stuck. Then hook with a piece of fishing line detached successfully recovered from the throat of a wounded bird.
Rescued swans released into the river and fed. As well, when there is nothing stopping a deep breath and spread your wings!
