They came to check us out as we kayaked from Tiree to Coll. The smaller, young ones were nearer the shore, grouped together as if in a nursery. The larger ones were feeding further out into the tide flowing between the islands.
They seemed to check us out by cutting across our bows and bumping us with their dorsal fins. It was very gentle, although enough to move the bow sideways, before the fin sank below the surface.
The experience was so mesmerising I almost forgot to take out my camera - the first time that has happened! We eventually stopped counting at 12 although we think there were more.
