Many thanks for the information. I spent 3 hours at Strumble Head yesterday from shortly after 9am. A couple of people turned up who knew the area and saw harbour porpoise so I knew I just had to get my eye in. A great northern diver and peregrine hunting helped pass the time. I saw a few individual porpoise briefly and from about 11:30 saw several pairs and a small group of 3 or 4 which kept surfacing in the same area.
Yep Ian. getting your eye in is crucial, glad you had some good sightings! allthinggood,cliff
