A couple of hours at Strumble from midday. Lots of sea bird feeding activity but just the occasional porpoise siting. Then a pod of at least 20 porpoise cruised in front of the watch point heading west. They formed a tight group, all adults, and just kept moving through, never getting distracted by all the seabird feeding. They were not too far out and in good light and frequent surfacing gave great views. I tracked them well beyond the lighthouse and they were still moving in the same formation. I've not seen porpoise travel in such a well ordered pod - very dolphin like.
Also 2 black terns and 2 sooty shearwater.
