Whale of a tale : social creatures in dangerous straits

The distressed, and distressing, behaviour of the pilot whales currently threatening to beach themselves in South Uist reflects the remarkable and highly complex nature of cetacean sociability. Philip Hoare, author of LEVIATHAN explains… 

Pilot whales, like the other toothed whales (odontocetes) of their sub-order – which includes sperm whales, killer whales and dolphins – form social groups, unlike baleen whales (mysticetes, such as the blue whale, the fin whale and the humpback), which generally travel alone or in mother-calf pairs.

Toothed whales may travel in massive pods of hundreds, even thousands; I’ve seen pilot whales in huge numbers in the Bay of Biscay, the Azores and Cape Cod. Between their two species (the long-finned and the short-finned pilot whale) they can be found in almost every ocean. The combined population may number more than 1.5m. They are nomadic, as opposed to migratory in habit (unlike the mysticetes), principally going where their food source takes them; these are deep-diving cetaceans, often feeding on squid at depths of 200-500 metres. They are also obviously highly successful – and part of that success must be due to their socialisation, held together by bonds we still do not completely understand.

We know that they communicate with each other continually. Dolphins have been proven to use signature whistles with which they announce their presence in the group. Sperm whales and pilot whales almost certainly use this method, too – unique in the animal kingdom. They focus these sounds through the bio-acoustical oil contained in their distinctively rounded heads, known as melons – in fact, enlarged noses. The necropsy on the first whale to die in South Uist indicated an infection in this area of the whale’s anatomy, which might have caused its disorientation – and also caused its fellow whales to follow it into shallow waters. Such strandings are sadly common, and occur around the world – even in the river Thames, where a pod of 20 pilot whales appeared in 1965.

The scenes of the whales in Scotland show typical behaviour. They are moving together, dependent on one another as a cohesive whole, but are composed of smaller family units of 10 to 20 whales. Genetic methods and observation, by scientists such as Hal Whitehead, of Dalhousie University, Nova Scotia, have proved that these are basically matriarchal, but with males staying with their mother’s group all their lives. As a result, these units are permanent and incredibly loyal. Hence the behaviour of the endangered whales in South Uist where the second whale to die was also a female. Photographs showing the whales raising their heads above water displays behaviour known as “spy-hopping” – they are literally looking up and around them. This may look cute but in this situation, where the animals are far too close to shore, it is a sign of near panic.

Pilot whales are no strangers to Scottish waters. In fact, it was the Orkney scientist, Thomas Traill, who first observed and scientifically named the pilot whale, Globicephala melas, in 1809, as a result of his firsthand experience of the cetaceans – either alive, at sea, or stranded on Orcadian beaches. “This kind of dolphin sometimes appears in large herds off the Orkney, Shetland, and Feroe islands,” noted Traill’s friend and fellow scientist, William Scoresby. “The main body of the herd follows the leading whales, and from this property the animal is called in Shetland the ca’ing whale, and by Dr Traill the deductor.”

It’s because of their propensity to act in unison, following one another, that these whales – also known as “blackfish” – were hunted as they still are, controversially, in the Faroe Islands, by being driven into shallow bays and slaughtered. Humans have even adopted pilot whale behaviour for their own warlike ends. The warriors of the Ngāti Kahungunu, a Māori iwi tribe, donned black cloaks and lay on the beach to lure an enemy iwi who would believe they were beached pilot whales and a source of ready food.

More benevolent encounters between pilot whales and humans have been witnessed off Gibraltar and the Canary Islands. Pilots are, like many cetaceans, highly inquisitive, and divers report the animals will often make physical contact. This is not always a good idea. A now-infamous YouTube clip shows a female diver being dragged down by a pilot whale and nearly drowning. Far from being a “vicious attack”, however, this whale was probably only playing, displaying the sociability of its species, which has brought them into such dangerous straits off the Scottish coast.



Whaling versus tourism: What’ are these gentle giants worth?

Philip Hoare: Leviathans in need of more protection


Wellington Notebook: A proposal to allow Japan commercial whaling rights in return for their agreement to stop whaling in the Southern Ocean is set to bring matters to crisis point

MY VIEW: New Zealand, the ‘land of the long white cloud’ where life is still relatively simple; New Zealand, that small group of three (yes, three!) islands in the South Pacific – is again raising the stakes on environmental  issues and showing the way. Through the work of Bill Ballintyne, it pioneered no-take marine reserves before they became the fashion.

And now, New Zealand is sending a clear sigmal : whaling is no longer acceptable; eco-tourism is the new way forward!

I have plucked the column from The Independent today to illustrate  my points…

Here in New Zealand’s capital, where I’m talking at the literary festival about my book, Leviathan or, the Whale, the subject of whales and whaling is not a remote one. Last Thursday, in a staged protest outside the Australian embassy in Tokyo, Japanese pro-whaling protesters attempted to hand a tin of whale meat to an embassy spokeswoman. The next morning, Tokyo police arrested Paul Bethune, the leader of the New Zealand anti-whaling group Sea Shepherd, for trespassing.

 Whales are a live issue for people used to seeing these leviathans swim past their beaches. Only a few hundred miles off their coastline, the infamous whale wars are being fought: between the Japanese, whose supposed “scientific research” kills 2,000 whales each year, and the eco-warriors of Sea Shepherd, dedicated to stopping the cull, at any cost.

Meanwhile, in Florida, last week witnessed the preliminary meeting of the International Whaling Commission. The proposal in hand – to allow Japan commercial whaling rights in return for their agreement to stop whaling in the whale sanctuary of the Southern Ocean – is set to bring matters to crisis point. All this is particularly ironic in the wake of recent events at SeaWorld in Orlando, where a killer whale dragged its trainer to her death. The worldwide media coverage of what was probably a terrible accident only underlines the passion and the fury that reverberates around whales, and how we treat them.

Down here in Kaikoura, the whale-watching capital of the world, every pub and café is filled with whaleheads sure of the need for one thing: action rather than words. I’ve spent the week in search of sperm whales. After hours of searching for the whales by use of a hydrophone – listening to their clicks under water – a magnificent, 16-metre, 40-year-old male whale surfaced. Named Tiaki, his name means “guardian” in Maori.

Once, hundreds of his fellow cetaceans visited these waters. Now Tiaki’s solitary presence may be a final warning: that whales face greater dangers than the Japanese hunt – from the pressures we all place on the whale’s environment, through noise, overfishing, climate change and pollution.

Orcas in captivity? It’s humans that should be locked up for animal cruelty!

The Independent reports how a killer whale in Orlando, Florida, has caused the death of a Sea World trainer.

MY VIEW: A wildlife holiday to Signifjord in Iceland, my wife and I were priviledged indeed to witness a huge  group or ‘pod’ of Orca (comonly called ”killer whales’) chasing salmon. The orca were swam directly alongside our small boats and, with the sun catching the spray of the waves and the stunning snow-covered peaks of the fjord set as the backdrop, it was a sight to behold!  Was I afraid these magjestic creatures – essentially large dolphins – were going to harm us perhaps by attacking the boat? No. These were wild animals, doing what they do best – moving, diving, hunting – fish! 

Whilst I am sorry for family of the trainer who was obviously well-intentioned in being a long-term staffer, and cannot guess to understand the circumstances. Do I agree with the idea of orcas in captivity, penned up to an inch of their lives in totally claustrophobic kennels? No, I am appalled that it still happens, and all rational reasons are swept aside when we consider the realities of what we are asking of these large and highly intelligent mammals.   Want to help out in the cause? Get involved with one of these charities: Born Free Foundation and  Whale and Dolphin Conservation Society.
