The shearwaters

One of our best clues to find dolphins are birds. We know that they sometimes follow dolphins and often hunt together. Since the beginning of July, groups of Cory's shearwaters (Calonectris diomedea borealis) have been observed in association with common dolphins. It's a magificent bird! In my opinion...it flies just centimetres above the water with the tips of the wings almost touching the surface. Check out here everything you need to know about this seabird. The other shearwater, the Balearic shearwater (Puffinus mauretanicus), is also in our company but this smaller member of the family is usually closer to Ponta da Piedade. This species is classified as critically endangered by the IUCN Red List. Dolphins? We had dolphins, common dolphins, bottlenose, porpoises (twice!) and the ocean sunfish (Mola mola).
