Why are people determined to believe that wind turbines kill whales

Coastal Australia is having another flare-up where locals are suggesting that wind turbines are killing whales. If this were the case, it would mean that those who want to save the planet would need to choose between climate change and conservation of whales.

Pictures put up, include images of whales on fire, among others – paid for Newcastle adn Port Stephens Game Fish Club. They suggested that the posters highlighted risks that were known for the whales, but there is no credible evidence that wind turbines have any impact on whales (except during building, but as the picture shows this is short-lived). Indeed Quentin Hanich who is the editor of the academic journal Marine Policy recently had to spend a week debunking a fake article that purported to come from his publication, which claimed that 400 whales would die a year, if a proposed wind farm went ahead. While the facebook post where it originated was taken down, the fake articles can be written far faster than they can be taken down. This offshore wind farm in New south Wales, is opposed by everyone from locals to MPs from outside the region – usually because the are opposed to renewable energy development.

This seems short-sighted- while Australia does have a large coal industry, most is exported (only around 30% is used in the country, and coal in electricity generation is now so much more expensive than almost any renewable generation, that its days are numbered) and of Japan,South Korea, Taiwan,and India which takes the majority, only India does not have a 2050 pledge of zero carbon – so if those promises are to be kept, the market for most of the coal will disappear within the next 25 years.

Opposition has been fanned by the coalition, and people like Baraby Joyce (a renewable energy opponent and climate change denier) have been loudly stating that support for renewables was a cult and the people should fight back.

Amanda De Lore is also fighting against it, and suggest that the 3 month consultation period was rushed and hidden (it was not) and that offshore wind is “not clean, green energy”. She stated that the project was not taking her groups concerns into consideration. However, when concerns are raised which do not conform with reality (like suggesting that offshore wind turbines are not green) they should be ignored. Importantly, when you compare the death toll of offshore wind turbines to a coal power plant, the numbers are stark with thousands more species killed by coal power.

This is part of the issue with public consultation. When opponents lace the population with falsehoods, you find yourself having to engage in a years-long effort to correct, before you can even have an intelligent conversation.

Scientists engage in “conversation with whale named Twain

Scientists claim to have had a 20 minute conversation with a humpback whale named Twain. By playing a recorded contact call, they encouraged Twain to approach the boat and circle it, responding to the contact call in a “conversational way”. Twain repeatedly matched aspects of the recorded call, in his response.

It seems odd that this would not be a regular part of their research, but at the current time it is not, and is thought to be the first communication of this sort between humans and a humpback whale.

It is thought that this behaviour supports our current way of looking for alien life of intelligence – like the humpback whale, aliens will be inquisitive enough to come and see what the species is that is making so much noise (the project is known as WHALE SETI). The project is using sensitive equipment to record whale sounds, and then using AI to analyse it.

Some discoveries include the identification of certain repetitive pattens and variations, which suggests an intent in the communications. We have already noted high levels of intelligence in animals like whales and dolphins, quite different to intelligence in humans. Unfortunately, the whales were not the aim of the research, and while the work may well be built on, in perhaps one day understanding more of what whales say, this project was to give insight into future attempts to communicate with aliens, not a current attempt to actually communicate with whales on earth.

Whales, Dolphins and Porpoises family tree

Cetaceans -Whales, porpoise and dolphins

Few people can avoid stopping to watch, if they spot cetaceans from a cliff. While the family is wide and varied, they are all pretty interesting. From some of the largest and most intelligent hunters such as killer whales to the largest animal on earth the blue whale.

Whale and dolphin watching tourism is worth a lot of money – this can be essential, as in many places the extra money helps a community survive. 

I hope, overtime, to make this section of the website as large a list of places to view cetaceans and people who will help you in that quest.

As might perhaps be suspected, all of the mammal species which have returned permanently to the sea, and developed breathing holes located on their back (and therefore perfectly placed for taking quick breaths) are  related.

So what is the most closely related living land mammal? Perhaps obviously, it is a species which spends much time in the water – the hippopotamus.

As with all of these pages, as we create pages for each individual species, they will be linked to the photo below.

So the baleen whales are split into three families, these are not large as there are only 16 species of baleen whales in the world. At the current time, there are roughly 1.1 million baleen whales in the worlds oceans

Below is a family tree of the group

 

Baleen Whales

Baleenideae – the rhight whales

 

The first  living split is Baleenidae, this family is not huge. The north atlantic and north pacific are closest related, these species are closely related to the Southern pacific right whales. Their name is unfortunate – it is called right whale for 3 reasons, it swims slowly, floats when dead and carries a large amount of oil. This lead to all these species being hunted close to extinction.

The other family is called Balaenopteroidea. Here species peel off slowly. I will list them in the order that they split.

The first split is the minke whale – of which there are 2 species, the common and southern minke whale, with the grey whale being the next most similar.

The next are the humpback whale and the fin whale followed by the Blue whale.

The last group of whales are from a group called the Brydes whales complex

This completes the list of baleen whales. The other branch of the Cetaceans is known as the toothed whales

Toothed Whale

.I am going to look at them in 3 groups, though the third is not particularly closely related to each other

  • Delphinoidea: This includes
    • Monodontidaes – Belugas and narwhals
    • Phocoenidae – The family of Porpoises (7 species) such as harbour porpoises and Vanquita

 

    • Delphininidae – these are the oceanic dolphins – 37 species split into several subfamilies which we will deal with one by one.
Subfamily Delphininae – 15 species (tamanend bottle nose dolphin only recognized as separate species, will build page for it at some point when photos are readily available.

Subfamily  Globcephalinae 11 species

Subfamily incerta sedis (latin for “of uncertain placement” )6 species

Subfamily Lissodelphininae 6 sppecies

Subfamily Orcininae

  • Inioidea : This includes 3 groups
    • Iniidae (only 1 of 5 genus remains -Inea (4 species: Araguaian river dolphin, Bolivian river dolphin  and Orinoco dolphin)
    • Lipotidae: which contains only one species: the Baiji or Chinese river dolphin
  • Pontoporiidae: which contains one species 

The next family is the beaked whales. There are 24 species, of which only 3-4 have been well studied. This is because they spend much of their time deep in the sea, it appears that each species does not have many members and they are incredibly reclusive in their habits.

One might ask how an air breathing animal can spend so much of its time deep in the ocean? Well the Curved beaked whale has had a dive timed at 138 minutes. More incredible, they only need around 2 minutes to catch their breathe before sinking back into the depths. This means that if required, they can spend just 20 minutes out of 24 hours at the surface – an incredible stunt.

There appear to be a great number of species that are extinct – these we will not list, but will mention each subfamily in passing.

Incertae sedis contains 5 extinct genus, Basal forms include 13 extinct genus

Subfamily Berardiinae contains 3 genus, 2 of which are extinct, but the third contains 3 living species (and one dead) .  

Genus Beradius

 

Next we cover the Bottlenose whales

Northern                                                                                                                     Southern and                                                        Tropical

Subfamily Ziphiinae  contains 5 genus, 3 are extinct, but two have just one species in each

Genus Tasmacetus: Shepherds beaked whale Genus Ziphius: Cuviers beaked whale

As you can see from the whale family tree, the sperm whales are separate from the rest. However, they are toothed whales so belong in this section of the page.

Species watch

Species watch

All species are important, often reintroductions have failed because a small unnoticed animal was missed. Over time, we will amass pages for as many species as possible. However, just as important is  seeing how species are closely related. As such as well as looking at species from a specific ecosystem or family, we will also include family trees of many of the families on earth. It should be noted, that this is to help you find wildlife you wish to see, so will never link to every species. In either way, these links to these will be placed at the top.
