Confidence: I'm as sure as I can be.
Notes: Several Shearwater seen flying northwards over the calm sea this evening but no pics possible. An otter was observed swimming at the surface about 1km offshore. It went under with the typical view of the humped back as it went down. A moment later a salmon or large sea trout leapt into the air just where the otter was seen diving. 5 salmon/large sea trout were seen leaping in total. A seal was also seen but the otter was unmistakable.
