The Largest Eagle in the World, Standing Over 2 Meters Tall, Feeds on Lions, and Its Predator Remains Undiscovered to Date
To date, there are 59 known species of eagles in the world. Eagles are carnivorous animals that prey on rodents, rabbits, snakes, and so on. Large eagle species such as eagles prey on goats and sheep. However, the largest eagle is said to eat lions for a living. There is no known enemy of the Argentine Giant Eagle to date.
Lions are the only species of cats with both male and female sexes, known as the 'Kings of the Grassland'. They are the top feline predators in Africa. However, lions still fall under the Argentine Giant Eagle's dominance.
The Argentine Giant Eagle is currently the largest bird known, living in the late Paleocene of about 6 million years ago. According to the fossils discovered so far, the Argentine Giant Eagle's standing height alone exceeds 2 meters, and its wingspan is 5.8-7 meters, and the longest can reach 14 meters, which can be compared to a modern Cessna 152 light aircraft.
With such a huge body, how did the Argentine Giant Eagle fly? It is not like the birds we often see, 'fluttering' its two giant wings to fly. Scientists used computer programs designed for aircraft to analyze the flight characteristics of the Argentine Giant Eagle. The Argentine Giant Eagle is a gliding master, it relies on the rising warm air currents in the Argentine region to fly.
If the conditions are good, the Argentine Giant Eagle's flight speed can reach 67 miles per hour. Its hooked beak shape and other features of the skull structure indicate that the Argentine Giant Eagle chooses to swallow its food whole.
However, the Argentine Giant Eagle is strong and powerful, but it is very lazy and doesn't actively hunt. It 'snatches opportunities'. Some experts believe that because the Argentine Giant Eagle has no enemies, it doesn't worry about any threats, and it doesn't worry about food.
Furthermore, the Argentine Giant Eagle has a very long lifespan, able to live for 50 to 100 years. Currently, most wild eagles can live for 20 years, and domesticated eagles can live for 40 years. Compared to the Argentine Giant Eagle, they are much shorter in lifespan, but the Argentine Giant Eagle reproduces slowly, about once every 2 years, and lays 1 to 2 eggs each time, and the young birds need the parents to take care of them completely, and it takes 16 months to become independent, and it takes 10 years to fully mature.
However, the Argentine Giant Eagle did not survive. According to the currently known information, the huge size of the Argentine Giant Eagle is likely the direct cause of its extinction. When the Argentine Giant Eagle was not yet mature, due to its huge size, it consumed a lot of energy when learning to hunt prey, and its survival rate was low. Also, because it reproduces slowly, the Argentine Giant Eagle was eliminated by the natural selection law.
It can be seen that the survival of animals is not only about having no enemies but also about being the victor. It is often due to some self-reasons that lead to extinction. Therefore, these former top-tier strongmen have disappeared into the long river of history. However, it is worth noting that the current China's 'Wild Animal Protection Law' clearly stipulates that all raptors belong to the second or above level of national protected animals.
