No the killer whale did not say "set me free"



Being a public broadcaster it would be hoped that the BBC would use a little bit more rigour when reporting issues particularly those that involve science. A case in point is an article in the Newsbeat strand written by reporter Talia Shadwell regarding research done on the mimicking behaviour of killer whales at an aquarium in France entitled: "Killer whale could be saying 'set me free'. 

The article is very disappointing due to the obvious lack of research and which appear to be based on views from the animal rights groups The Born Free Foundation and Whale and Dolphin Conversation - both known for their objection to animals maintained in captive care.  Further, there appears to be absolutely no effort to contact Marineland in France whose animals and facilities were used in the research cited or indeed any other zoos or aquarium that display whales or dolphins.

First, the breeding ban on whales and dolphins in France mentioned in the report has been lifted by the French courts after being successfully challenged as it was not based on science or in the best interest of animal welfare. This would have been made clear to the reporter if they had bothered to contact Marineland.

The picture of a killer whale in captivity in the Netherlands was also deceptive because it did not explain that this was Morgan a young killer whale that was rescued in a distressed state suffering from malnutrition on the Dutch coast in 2010. The picture is her in temporary accommodation while she underwent rehabilitation.  

Picture of a killer whale in the BBC article was, in fact, Morgan a rescued animals in temporary accommodation in the Netherlands while she was being rehabilitated.
She successfully returned to full health but unfortunately due to her young age and the inability to find her original social group, which was believed to be located possibly in Norwegian waters, she was relocated to a large facility for killer whales in the Canary Islands in November 2011. This was undertaken under the direction of the Dutch government. 

Morgan remains there today in the company of other captive bred killer whales. Since that time it has been discovered that she was either deaf or has a severe hearing impairment which is possibly one of the reasons she stranded and had to be rescued. This again would make any attempts to release her back the wild inappropriate. 

Second, the issue of the bent dorsal fin in some male killer whales in captivity is often cited by animal rights groups as a sign of compromised welfare. However, there is no scientific evidence to support this contention and in fact, bent dorsal fins can be seen in wild killer whales and this has been cited in published research.

"....The collapsing, collapsed and bent  dorsal fins found on the New Zealand killer whales do not appear to be uncommon in this population,  with 23%, of the adult males having some form of abnormal fin..." (Visser, 1993).
Further, as this seems to be a gender specific issue regarding some male killer whales (either in captive care or the wild) as a measurement of fitness and health it cannot be used as an accurate determination of such criteria as compared with more standardised physiological parameters such as blood analysis.


Third, the comments regarding releasing animals back to the wild cited the release of a former captive killer whale called Keiko. This project was claimed to be a success and this is incorrect. 

Keiko was released back to the wild but failed to integrate into wild groups of other whales.  He eventually found his way to Norway and ended his days being cared for by humans in a 
fjord before dying of suspected pneumonia some months later.

In the review of the release, published in the peer review journal Marine Mammal Science, the authors concluded.

The release of Keiko demonstrated that release of long-term captive animals is especially challenging and while we as humans might find it appealing to free along-term captive animal, the survival and well being of the animal may be severely impacted in doing so.  (Simon, Hanson, Murrey,Tougaard, and Ugarte. 2009)

As to the actual research which - demonstrated that mammals were capable of mimicking human speech - this is not actually that new.


Research of this nature was conducted back in the 1960s by the controversial dolphin researcher Dr John Lilly. Ironically, the BBC showed a documentary in 2014 entitled "The Girl Who Talked to Dolphins" which highlighted his research and had recorded footage of one of the dolphins mimic English words and phrases.
 

Further, it's not just dolphins that have been known to imitate human speech as it has also been seen in belugas such as an animal called Noc that was studied by Dr Sam Ridgeway under the US Navy marine mammal program (Ridgway, Carder, Jeffries and Todd, 2012). There was even in one instance of a seal called Hoover who lived at the Boston Aquarium in Massachusetts imitating human speech. 

Nevertheless, various scientific projects in the past (predominately the 1960s) where efforts were made to teach animals (such as dolphins or chimpanzees) human language, were abandoned as researchers could not produce any tangible evidence that the animals could be effectively taught to communicate with human beings in anything approaching a discernible human language structure. The net result was that funding from such organisations as NASA, who funded some of John Lilly's work, was withdrawn.  

Further, chimpanzee research also faulted when the psychologist Herb Terence maintained that much of his research was the result of the Clever Hans effect and not the animals actually having the ability to communicate with humans. 

Perhaps one of the fundamental problems is that animals are generally incapable of speaking a language in the same terms as human beings. As Dr Justin Gregg points out in his 2013 book "Are Dolphins Really Smart - The Myth Behind the Mammal" human beings (Homo sapiens) are the only animal species that have a native language; the reality is that humans have language and animals communication. The depth and sophistication of human language exceed anything that we know regarding animals in the wild and their ability to communicate with each other. 

In conclusion, the premise that the killer whales (if they could speak and communicate with humans) would be that they wanted to be set free could turn out to be the fact that they are quite happy where they are in the protective environment of a zoo and aquarium.




A section from the 1983 Nova documentary "Signs of Apes and Songs of the Whales" featuring cognition research featuring dolphins and sea lions. At the University of Hawaii, two dolphins are being taught to comprehend the rudiments of grammar. And in California, the controversial John Lilly is teaching dolphins to mimic--and perhaps one day reply to--the computerized human voice.

Animal-Rights Group Attack Richard Branson's Virgin Travel



The Whale and Dolphin Conservation Society (WDCS) - now branded Whale and Dolphin Conservation (WDC) - is still banging the drum for the contentious and discredited animal-rights film 'Blackfish'.  Its latest efforts is a press release to travel journalists such as The Daily Telegraph alerting them to their campaign to put pressure of various travel firms (including Richard Branson's Virgin Travel) not to promote and sell packages that included trips to the SeaWorld marine park in Orlando, Florida claiming that companies such as Virgin are: "...profiting from the cruel captivity industry".


One interesting point that should be noted is that (as predicted) there is now a considerable amount of  'mission creep' from these groups protesting against captive killer whales as they have now moved on to protesting about the captive care of all whales and dolphins (cetaceans); a situation that all zoological collections should be aware of if they display marine mammals or other large charismatic species such as elephants.

The claims within the WDC press release follow the usual predictable pattern of 'cut and paste' animal-rights rhetoric including issues such as wild capture, animals' wild ranging behaviour and survivorship.

"...WDC claims that five SeaWorld orcas were taken from the wild and that “most of the orcas held by SeaWorld die in their teens.” It also says that an orca at SeaWorld would have to circle its tank 1,400 times to match the distance it would naturally travel in the wild each day..." The Daily Telegraph. 1 March 2014
Indeed, five of SeaWorld orcas were taken from the wild, which is indeed the case, but WDC is a bit more selective with other facts.  The last wild-caught killer whale at SeaWorld was caught over 30 years ago in Iceland in 1983 for a Canadian aquarium Sealand of the Pacific which when it closed in 1991 transferred its animals to SeaWorld.  It should also be noted that 21 of SeaWorld's 26 killer whales were born in captivity; these figures exclude the 4 animals born at SeaWorld that are now displayed at Loro Park in Spain.
 

WDC comments regarding how far wild killer whales would travel in the natural environment are both naive and simplistic as in the case of many wild animals (such as elephants) they move large distances due to pressures such as acquiring adequate food resources.

As to survivorship, the average age of killer whales at SeaWorld is approximately 16 years but this is statistically biased towards young animals due to a captive breeding programme which did not successfully start until 1985.  SeaWorld considers its animals survivorship is equivalent to that of the wild.

Moreover, as the WDC has brought up the issue of all whales and dolphins in captive care it should be noted that published survivorship research on the bottlenose dolphin (the most commonly cetacean kept in zoos) shows its survivorship exceeds its wild counterparts.

Perhaps one of the biggest puzzles regarding the WDC is why a 'conservation charity' is spending well-meaning public donations on dubious concerns regarding animals living in zoos and aquariums to the point of paying for an anti-captive campaigns officer?  When the fact is that the real conservation issues for whales and dolphins are not in well run zoological collections but in the wild.  Moreover, parks like SeaWorld spend considerably more time and money on the welfare and research of marine mammals than groups like WDC.  


A rather unfortunate and ironic meme that was posted badged with the WDC logo when 'Blackfish' was rightly not nominated for an Oscar for Best Documentary.
