April has come to an end and we are now looking back at our sighting statistics from the month. During April we encountered 7 different cetacean species, in order of most sighted: common dolphin, bottlenose dolphin, fin whale, blue whale, sperm whale, striped dolphin and humpback whale. It is this time of the year, and at least for another month from now, that we have the baleen whales, like blue whales and fin whales, but also sei whales, migrating past the Azores on the way to their North Atlantic feeding grounds. So far the season as not been as strong as in previous years, but at least we have been seeing cetaceans every tour. As well as whales and dolphins we have also seen other marine species such as many loggerhead turtles, ocean sunfish, flying fish, jellyfish, Portuguese man-o-war, salps and seabirds including Cory's shearwater, manx shearwater, Macaronesian shearwater, bulwer's petrel, yellow-legged gulls, great black-backed gulls, common terns, great skua, pomarine skua, sanderlings, ruddy turnstones and northern gannets.
