00:00Have you already imagined aigle so big that he could reach your coude?
00:04No, not really. But now that you are talking, yes.
00:08It seems terrifying, but don't you do it too, it doesn't exist.
00:12Finally, it doesn't exist.
00:14I present you the Aigle of Aast, one of the biggest aigles who has ever been on our planet.
00:20His height could reach 3 meters and it could weigh up to 10 kilos.
00:25It's about the weight of a caravan wheel.
00:27He lived in Newfoundland and it was in Pensacola in Sparrow after a few centuries.
00:33At his great age, this incredible beast was the supreme predator.
00:37He chased the pigs of big birds inaptes to fly, like the moa.
00:41He was also very robust, with its 3,6 meters and its 200 kilos.
00:47How the Aigle of Aast could become so big, ask you?
00:51Well, he had a lot of food in his environment.
00:54His ancestors were younger and lived in the forest.
00:57But when they started to disappear, the prairies were dead.
01:02And the Aigle of Aast had a habit of hunting more grosses than the discovered.
01:07With the Thames, the Aigles of our Aigle had so grown up and made them grow up, allowing them to
01:14destroy the great volatiles.
01:15The Aigle of Aast was also very intelligent.
01:18He was very curious and hunted in a way unique way.
01:22Instead of following his prey, he waited for them to stop near a river.
01:25Then he found on them to catch them.
01:28This method of hunting was effective and allowed him to capture big birds with a minimum effort.
01:34He also had a unique unique characteristic.
01:37His beak was much bigger than the other Aigle of Aigles, which allowed him to well hold his prey.
01:42According to his strength, we think that the Aigle of Aast could raise heavy objects up to 45 kilos to
01:48bring them up.
01:49All this is very frightening, but this Aigle was not so bad.
01:53In fact, it was rather romantic.
01:56The Aigle of Aast was a solitary hunter and scientists thought that he was monogamous.
02:01The Aigle of Aigles had a great importance for the indigenous peoples of Nouvelle-Zélande.
02:12They often used his plumes for clothing and decoration.
02:16We also considered him a symbol of force and power.
02:20Like many other animals, the Aigle of Aast was finally disappeared because he lacked food.
02:25Remember when I told him that his favorite animal was called Moa?
02:29When the Moa began to disappear because of the development of the hunting,
02:34our Aigle of Aast could find enough to survive enough.
02:38This Aigle of Aast, a part of the indigenous history of the Nouvelle-Zélande and Ethnus,
02:45reminds the impact that humans can have on the environment.
02:49It is also an example of the way evolution makes a species adapt to its environment.
02:55I would like to be curious about the Moa.
02:59Try to imagine the Grand Cousin of the Autruches.
03:01He also lived in Nouvelle-Zélande for thousands of years before moving to the XIV century.
03:07And he was impressive.
03:09He had a long tail and a small head with a beak that he used to eat for eating leaves.
03:14It was a bit of an oisee, but his ailes minuscule didn't allow him to fly.
03:19However, he used them to be balanced and to appear more big face to his predators.
03:24The Moa lived in the wild regions of the country of Kiwis, and he was nourished by various plants,
03:30flowers, flowers and trees.
03:32He was totally vegetalian, or herbivore, if you prefer a more sophisticated term.
03:39He used his beak to collect the leaves and branches of trees.
03:42The Moa was a solitary creature who lived alone or in small groups.
03:55He was more active during the day and was relatively docile.
03:59Quant to his predators, nothing was afraid of the Moa that aigle of haste.
04:04He also played a role important in the ecosystem of Nouvelle-Zélande.
04:08Each time they, eh bien…
04:11allait to the toilet, they provided to the soil of nutrients rich as well as grains.
04:17This contributed to fertilize the land and aid to the growth of plants.
04:21The first colon of Nouvelle-Zélande were the Maori, who arrived on the island over the XIII century.
04:27They immediately considered the Moa as a source of great food.
04:31And they began to chase this fish for its meat, its plumes and its eaux.
04:37As soon as the population of Moas began to decline.
04:41The Maori also had a large forest forest for agriculture and installation of colonies,
04:46which changed the habitat of Moa, and made its survival more difficult.
04:51During the XIV century, the fish was eaten.
04:54We could not conclude our list of gigantic and eaten without talking about the elephant.
04:59It was also a great animal incapable of flying, and he lived to Madagascar until its extinction
05:05in XVII century.
05:06He could measure 3 mètres of high and weigh up to 500 kilos.
05:10This is what made the most great animal that has ever existed.
05:14We saw this creature for the first time in XVI century, and it was quickly becoming a
05:20subject of fascination for naturalists and collectors.
05:23We described it as having a thick plumes, thick plumes, thick plumes, long and gros bec.
05:29His legs were thick and strong, with three teeth at each leg, each each ending with a
05:35grip.
05:36Despite its size and strength, the elephant elephant was an herbivore, and its menu daily
05:41was mainly composed of fruits, leaves and other plants.
05:45Quant à sa vitesse, ce n'était pas exactement un champion.
05:49Il se déplaçait très lentement, et passait la plupart de son temps à Churchill de la
05:54Nooriter.
05:55Aussi grand et imposant qu'il fût, l'oiseau elephant n'était pas particulièrement agressif.
06:01Il était plutôt indifferent aux humains.
06:03Et puis s'il était assez timide, il était assez difficile d'en apercevoir un dans la nature.
06:09Les œufs de l'oiseau-éléphant étaient si gros que les habitants de Madagascar les
06:14utilisaient parfois comme récipients pour la cuisson.
06:17Ils étaient également assez gros pour nourrir des familles entières.
06:21Un seul œuf pouvait mesurer jusqu'à soixante-tiens centimètres et peser 100 kilos.
06:26Les plumes des oiseaux-éléphants étaient également très épaisses et isolantes.
06:31Ces créatures auraient donc pu survivre sous des températures très froides.
06:35Leur langue était tout aussi spéciale, tellement longue, que les oiseaux pouvaient atteindre
06:40leurs yeux pour les nettoyer.
06:42On pense que le dernier oiseau-éléphant a disparu au XVIIe siècle et l'espèce a été
06:47officiellement déclarée éteinte au XVIIIe.
06:51Cependant, des gens croient avoir aperçu cet oiseau ici et là au cours des siècles suivant
06:56son extinction.
06:57Et certains scientifiques pensent que de petits groupes d'oiseaux-éléphants pourraient encore
07:02exister dans des régions reculées de Madagascar.
07:05Il est peut-être éteint, mais l'oiseau-éléphant a eu un impact durable sur la science et la
07:10culture.
07:12Ces œufs, qui étaient les plus grands de tous les oiseaux, ont été retrouvés dans
07:16des sites archéologiques et sont maintenant exposés dans des musées du monde entier.
07:21Cette fascinante créature a également fait l'objet de nombreuses études scientifiques,
07:25et on l'a utilisée comme modèle pour comprendre l'écologie et l'évolution d'autres
07:30oiseaux inaptes au vol.
07:32Dans la littérature aussi, l'oiseau-éléphant a fait de nombreuses apparitions, et il est
07:37souvent dépeint comme une créature puissante et mystérieuse.
07:41Selon une légende, l'oiseau-éléphant était si grand qu'il ne pouvait pondre qu'un œuf
07:46à la fois, et que cet œuf était si gros qu'il fallait plusieurs personnes pour le porter.
