In theory it’s lovely to have otters on the lake, like this one caught on camera last night. The reality is that they have cleaned out all the fish and if this one stays much longer it will kill all the young goslings, ducklings, moorhens and dabchicks. In years when an otter takes up residence we have a total clean out of all the young waterfowl. Our first families of greylags are on the lake now so I hope the otter will go elsewhere. It comes up underneath and pulls each bird down. I have even seen one take a herring gull down and, after drowning it, take it away over the dam and down the valley.
