20 July 2019; DW: Tourists and a helicopter pilot have reported dozens of dead whales to authorities in Iceland.
David Schwarzhans and his American passengers, who were on a sightseeing tour, counted 50 long-finned pilot whales washed up on a remote beach in the west of the Nordic island.
The group took a video of their discovery on the Snaefellsnes Peninsula and alerted police on Thursday but the details were only made public on Saturday.
Schwarzhans, a pilot for Reykjavik Helicopters, described a "very sad scene," adding that "there might have been more. Some were already buried in sand."
It is not clear why the cetaceans washed ashore or how long they had been there. However, some reports suggested they had most likely swum towards shore at the same time and died of dehydration.
Why so many?
Robert Arnar Stefansson of the Icelandic Institute of Natural History told the Icelandic radio station RUV that while it is not uncommon for pilot whales to be stranded at this time of year, the number of whales found is unusual.
Marine biologist Edda Elisabet Magnusdottir told RUV that pilot whales are pack animals with strong social ties, which means they would be likely to follow others ashore.
Strong currents in the area and the shallow seabed makes it harder for them to swim back into the open water, she added.
Despite their name, pilot whales belong to the dolphin family and are only exceeded in size by the killer whale.
Pilot whales can be found almost all over the world. A large population inhabits the North Atlantic Ocean around Canada, Greenland, Iceland and Norway.
Last year, residents got a large group of whales to turn away from a spot on the opposite side of the peninsula.
