    Thank you for your amazing quality work. I really didn't understand how your channel still has so few subscribers. Hang in there and keep them coming when you can.

    Always eager to hear a Kiwi take on the failures and shortcomings of their cross-Tasman neighbours! 😉
    Love to hear your version of the Great Emu War!

      I like to include some of my own photography when I get the chance. It means actually doing something with my photos instead of letting them gather dust in my hard drive!

    I think people forget just how much megafauna was wiped out by the Polynesians in their island hopping. So much unique fauna that evolved on Islands was decimated by the Polynesian peoples - particularly New Zealand's amazing megafauna, and Hawaii's larger species. And somethin else, that nearly always goes unspoken, is the fact that virtually all Australian megafuana-extinctions (during the Holocene) occured only after the Aboriginals' arrival.

      Well that’s only part of it

      Yes! Thank you for saying this! The natives had no concept of preservation of species and/or what it meant to over hunt and the consequences of their own actions. It's wonderful that we civilized people know better today and have set up safeguards to prevent over hunting/fishing/farming from occurring and ravaging the Flora, Fauna, and the land itself any further. We may not be able to bring back the countless unique creatures that the Aborigines and Polynesians drove into extinction, but we can (and must) protect the ones we have left today and heal the land as best we can for future generations to appreciate 🙂

    They may not be alive today but did those early birds get the Worm?

    Interesting how both ratite chicks and piglets have similar, cryptic patterns

    I would have loved to see Giant Moa's and the Hawst eagles 🦅 before they went extinct. Same as the elephant birds and dodo birds. Also getting to See Terror Birds would have been INSANE

    There is an awesome kiwi band called The Beths, their song Expert in a Dying Field is so good, you should check it out if you have never heard of them!

    penguins are also flightless birds, so what makes then different from these other flightless birds? some of them are pretty large, too!

  • @raphlvlogs271

    are the introduced cane toads a threat to them since cassowaries can get poisoned from predating on them like many other opportunists

      Interesting question! There is very little research done on this topic, but what I could find suggests that birds in general are more likely to survive the toad's toxins than the Australian mammals and reptiles. While cane toads are a massive issue in Australia, hopefully they aren't impacting cassowaries too much!

    numbers are very low ...Car accidents , destruction of habitat and inbreeding . Sadly this relic of the megafauna era in Australia is struggling . I doubt it will survive in the wild and only specimens will be a captive breeding program . Stunning bird from a very ancient time .

    Just saying but I would love to see a video on the genus bison and the genus is made up of only two living species the American bison or as it is also known as the Thunderbeast and the European bison aka Wisent but the rest of the species in the genus are extinct and these include Bison schoetensacki aka the Pleistocene wood bison, Bison antiquus, Bison latifrons aka the long horned bison, Bison occidentalis and Bison priscus aka the steppe bison and the ancestors of American and European bisons first appeared in south and Eastern Asia between 2-3 million years ago and the ancestors of the American bison went to North America where they evolved into the American bison while the ancestors of the wisent migrated from south and east Asia to Eastern Europe and the Caucasus and both species of living bison are even broken down into subspecies with the subspecies of the American bison being Bison bison athabascae aka the wood bison which live in forests and they are the largest land mammal in North America weighing more than a moose with a large male wood bison reaching up to 2,000 pounds while an adult female bison weighs 1,200 pounds and an adult moose weighs around 1,500 pounds which means a male wood bison can be around 500 pounds heavier than a moose. The other subspecies of the American bison is the more commonly seen, more recognizable and more popular Bison bison bison aka the plains bison and these are the bison that inhabit and roam the Great Plains and prairies of the midwestern and western United States and they along with the wood bison used to inhabit the eastern United States with their range in the eastern us spanning from New York in the north to Florida in the south and from the Mississippi River in the western part of the eastern states to the Atlantic coast however by the 19th century they were hunted out of the eastern states and now the only places in the us where wild plains bison are found is the western and midwestern United States. But while the American bison has two subspecies the European bison aka wisent had 3 subspecies and these subspecies are Bison bonasus bonasus which is the only living subspecies of the wisent and it inhabits the Forests, Woodlands, grasslands and plains and its currently restricted to central and Eastern Europe including the nation’s of Belarus, Lithuania, Poland, Russia, Slovakia and Ukraine however the other two subspecies of the wisest are extinct and the other two subspecies are Bison bonasus caucasicus aka the Caucasian wisent which inhabited the the Caucasus Mountains and it was hunted by carnivores like the asiatic lion, Caspian tiger, steppe wolves and the Syrian brown bear however in 1927 the last Caucasian Wisent became extinct. The other subspecies of the Wisent to go extinct was Bison bonasus hungarorum aka the carpathian wisent and the carpathian wisent inhabited the Carpathian Mountains in Moldavia and Transylvania and it went extinct in 1852.

      Someone just made a video, literally this week, comparing both Bison species on RUclips. I think it was made 2 days ago if you search for it.

      @ oh okay thanks for letting me know about the video.
