I am fortunate to have a pond 50 yards from my front door - a couple of acres of water, rushes and scrub. The current population is a pair of mute swans, 6 cygnets, one of last years young and a whooper swan who broke a wing tip on the power line in February 2015. The carry on between the pair of mute swans and the other two makes Game of Thrones look like handbags.
This evening there was a tremendous commotion just after I fed the family some oats. There was a dark shape in the water and the cob was going berserk. Assuming it was a mink I legged it down to the pond looking for the largest stone I could find to give a hand. To my amazement the cob was beating the tar out of a 3/4 grown otter and he really did not need any help from me. He was hissing furiously and beating the otter with paddles and wings. The otter was hiding in tree roots in shallow water, bleeding from head wounds . He came onto dry land but went back when he saw me.
Now mute swans are two a penny in comparison with otters, but I rather hope the otter goes somewhere else for his tea!
To crown it all I dropped the phone on the way down so no photos.
