In our perception of reality, most birds are seen as disney princesses' cute, feathered friends, annoying troublemakers in the city, and terrible enemies of the domestic animals in the village.

<h1 class="pgc-h-arrow-right" data-track="4" >10, Argentine Giant Eagle</h1>
Let's start with the Argentine giant eagle, one of the largest flying birds that ever existed on Earth. This elegant bird lived 8-6 million years ago in the late Miocene, a golden age for birds. The bird lived in what is now Argentina, where its fossils were first found and recorded in 1980. It is currently estimated that the typical Argentine giant eagle is 1.5 - 1.8 meters tall, weighs about 70 - 72 kg, and has a body length of about 3.5 meters. To survive, the Argentine giant eagle eats about 4.5 kilograms of meat a day, and it is said to kill small animals such as sloths or armadillos to obtain food. This big bird may also catch prey from other predators, because no one dares to challenge something so big.
The Argentine giant eagle, no doubt, is a flying bird, but scientists still can't figure out how it does it. Especially when you think about its impressive weight, know that the Argentine giant eagle is much heavier than any bird we know today. So how does it lift itself up? This is a problem! For a long time, the Argentine giant eagle was considered the largest flying bird ever. But, not so long ago, it was replaced by another giant bird on our list.

It was this new giant bird that drove the Argentine eagle off the list of the largest flying birds. In 1983, the Mulberry Pseudolodon was discovered in South Carolina, USA, and was documented in 2014. The Mulberry Pseudolodon lived in the Oligocene about 25 million years ago. Its most incredible feature is its astonishing wingspan, which is a terrifying length of 7.5 meters. Compared to the Argentine Giant Eagle, it is a lightweight bird of 22 - 40 kg. But of course, it's taller and wider. It is a seabird, and scientists believe that the Mulberry Pseudoodont bird flies all day on the surface of the water, looking for prey, grabbing prey from the water with a strong beak and dentures. It is worth mentioning that the Mulberry Pseudo-toothed Bird mainly eats fish and squid.

Now let's go back to land and see some huge but flightless birds. The first of them, the Thunderbird, inhabited the territory of modern Argentina between 17.5 and 11.6 million years ago. This bird is a dangerous carnivore with an astonishing size. It weighs between 350-400 kg and is more than 2.8 meters long. It is the most powerful horror bird ever, a super cruel killer. When it sees a possible prey, it will try to jump up and squash the poor thing. And, if the prey is able to escape, the thunderbird will chase it and attack it with its strong legs. You can imagine what a terrible bird this is!

The South American dinosaur was one of the top predators of the Miocene period. Like many other giant birds, this 130-kilogram bird lives in the forests and grasslands of Argentina. The dinosaur is about 2.4 meters tall, has a large head of 65 cm long, and a strong long neck that can easily handle it. This bird has a spectacular hook-like beak that helps it easily pierce into the body of its prey. Dinosaurs mainly hunt small and medium-sized animals, they are like horses in ancient times, and can even kick the butt of saber-toothed tigers. Saber-toothed tigers and cranes most likely live in peaceful environments, sharing habitat as top predators, but the battle between this big cat and this big bird must be epic!
<h1 class="pgc-h-arrow-right" data-track="51" >6</h1>
This amazing big bird has lived in New Zealand for over 1 million years. But when ancient Homo sapiens came to the arena, even the most powerful species had to stand the test. This giant eagle is considered the largest eagle ever built, and it weighs impressively, ranging from 9 - 15 kg. Its wingspan is up to 2.6 meters, which is a fairly small number for such a large bird. The Haast Giant Eagle is a very skilled predator, its main prey is moa, other large but flightless birds, and... mankind. This giant eagle is strong enough to prey on human children. However, humans are smarter than Haast Eagles, so they were exterminated by humans in the 15th century.

This bird is the giant moa, the prey of our feathered friends before. However, we should not underestimate these gentle giants just because they are herbivores. Moa are large, about 3.6 meters tall, weighing more than 226 kilograms, but that's not the limit. One of the fossils found belongs to this giant bird, which is estimated to weigh about 278 kilograms. The legs of this giant bird are so powerful that it can kick anyone who is not very smart to death. Giant moa lived in New Zealand for 40,000 years, but in the 16th century, they completely disappeared from the world due to the arrival of the most mischievous species on Earth, humans.

Extinct giant penguins lived 60-56 million years ago, just after dinosaurs left the earth due to premature extinction. The species lived in Antarctica, but at that time the climate there was much more pleasant, with a warm subtropical climate perfect for sunbathing, fruit cocktails and giant penguins. Giant penguins are as tall as modern males, about 1.7 meters tall and weigh about 90 kilograms. This large bird will prey on fish and even larger marine life. Kimummanu is the oldest giant penguin ever found, and probably the largest of them. It's not an easy animal to catch, and scientists don't think many animals dare to wrestle with giant penguins.
<h1 class="pgc-h-arrow-right" data-track="54" >3, Australian supergiant</h1>
After a giant penguin, do you still want to see a giant goose? Let's say hello to the Australian supergiant bird, which can't fly and has no wings, but is a powerful ancestor of swans. It is a predator, not the prey of other animals fifty thousand years ago. This huge bird weighs 0.5 tons and is about 3.1 meters high, which is simply a character in a horror movie. Scientists debate the food preferences of the Australian supergiant behemoth because some of its features suggest it is a herbivorous and others suggest it is a carnivore. It could also be an omnivore, and if that's true, I can only imagine how this big bird really feels when it chases after other animals.

The Carlinken crane, the largest of the dinosaur family, is a giant flightless carnivorous bird that lived in modern Argentina 15 million years ago! It is 3.2 meters tall and weighs about 250 kg. Scientists have discovered the skull of the Carlinken crane, which is surprisingly large, and is about 71 centimeters long, the largest skull of any bird. The Carlinken crane may have killed its prey with its huge mouth, or lifted it into the air and fell to the ground. I want to believe that this is not a pleasant picture!

Let's end our list with the most dangerous birds still alive on earth. It's the crane ostrich. A typical crane ostrich is between 1.5 - 2 meters tall and weighs between 58 - 60 kg. This flightless bird is a very successful omnivorous animal, and they prefer to eat fruit. However, crane ostriches do not like humans, and when they fight humans, they usually defeat humans. Therefore, the crane ostrich is called "the most dangerous bird on earth".
