NB: For the Info of local Birding/Nature colleagues
As usual when one observes something different or unusual, one does not have the right camera available. I went out during the late afternoon to take a few landscapes and ended up on a road that runs alongside a river.
My 'Spotter' observed movement in the centre of the river which as you can see below turned out to be an Otter.
I only had a camera with a 18-105mm lens attached and had to crop these shots to get an ID record.
For local colleagues the position was about 300 metres North of Deeping HB Water Tower.
