Three animal rescuers had been trying to capture the injured duck for many days but all the efforts were in no vain as the bird managed to escape every time. Karel Makon, from animal rescue centre DESOP Plzen, said: "The first time we tried to catch him was in April. But it was in vain. We tried many times but he always flew away, and he recognised us. He couldn't be caught." It was until they decided to manage a coordinated kayak chase to get the bird, they managed to rescue it and take him to a vet.
