Over the past few weeks the camera has seen a lone otter going through the culvert about twice a week. At the beginning of last week we had quite a lot of rain and the water once again spilled over the sluice gate. Twice in the same day the camera recorded something I haven't seen before - an otter fishing in the culvert. I reckon this is the dog and it is fascinating to see how he systematically sweeps from side to side looking for fish.
The lone otter detected the next time was a cub, which was surprising. The camera records for only 20s in infrared mode so we don't quite see it make it up the ramp but I presume it did as there was no subsequent recording. Quite why it was on its own isn't clear but I expect mother was nearby.
Two hours later the camera briefly glimpsed a small otter coming back through the pipe - detecting a small cold wet otter in water isn't easy for the sensor. Another two hours later mother appeared with both cubs, again heading north. The cubs are slow though the fast-flowing water and the camera's 20s cut-off means we don't see them get up the ramp. They were too far away to trigger a second recording.
Two days ago they went through again, this time in much shallower water, although it is very slippery. And yesterday a large solo otter went through, presumably the dog. He walks slowly to make sure he doesn't slip.
