Four bottlenose dolphins

Half an hour into the survey period, two bottlenose dolphins were observed travelling into the survey area from the west with irregular surfacing, thought to be foraging whilst on the move. The pair travelled to the cardinal marker, where they were further observed taking long dives, thought to be foraging at depth, before disappearing for the rest of the survey period. At the beginning of the second half of the survey period, two more bottlenose dolphins, one identified as a calf, had travelled close to the harbour wall and were last seen travelling east past the wall, before disappearing for the rest of the survey period.

Five bottlenose dolphins

At the end of the first half of the survey period, four bottlenose dolphins, including a calf, were observed leaping/tail slapping/lunging between the harbour wall and the headland. A fifth bottlenose dolphin joined the group by the beginning of the second half of the survey period, joining in with the initial group’s behaviour. The group then split into two groups. The first was of three individuals, which carried on with their splashy behaviour, whilst the second group of two individuals were observed taking long dives, thought to be foraging at depth, a short distance away. In the last half an hour of the survey period, the groups soon merged again into one group of five individuals, and were last observed travelling, with regular surfacing, out of the area in a north-westerly direction.
