How do eagles see their prey on the ground at an altitude of about 1,000 meters? Why are they almost all over the place? I believe that many friends are more curious about this question, eagles as aerial birds of prey, its food almost comes from the ground, so how do they be fast and ruthless? In fact, about this problem, it mainly includes the following factors:
1, the eagle's eyesight is particularly good.
Eagle is a collective term for small and medium-sized eagles, such as goshawks, sparrowhawks, kites, eagles, and harriers, and people refer to them collectively as eagles, or eagles. Regardless of the specifics, they all have almost the same quick-eyed, agile and fierce characteristics, which is one reason why they are classified as birds of prey.
Eagles generally prefer to live on the cliffs of canyons or on the higher branches, and during the day they will hover high in the air and wait for opportunities to hunt.
People looking at the ground from a high altitude often find that their vision is not clear, but eagles can clearly see the prey on the ground, first of all, relying on their super vision.
The pupils of eagles' eyes are very large, making their vision resolution very high, and secondly, their eyes have a high degree of photoreceptor cells, which not only facilitates more light entry, but also allows them to pay attention to more details.
In addition, the structure of Hawkeye is very peculiar, their eyes have two concave structures, one is the middle concave of the eye, and the other is the lateral concave, these two concave structures are distributed in different areas of Hawkeye, the former can keenly find objects in the anterior visual field; The latter receives an image of an object in front of the eagle's head, with the sharpest binocular visual area in front of it.
In short, the special structure of the eagle eye makes them 10 times stronger than humans, for example, eagles can see hares running on land more than 3,000 meters away, so they can easily find prey and capture them even if they hover at an altitude of thousands of meters.
2, the eagle sprints very fast.
Eagles prey fast and accurate, one reason is inseparable from their super vision, and another reason is that they fly very fast. Under normal circumstances, eagles generally fly at a speed of 80km/h, but when they dive down to hunt prey, they can reach a speed of 360km/h. Of course, the speed of eagles in birds is not the fastest, the fastest is adult frigate birds, they can sprint up to 418 kilometers per hour when hunting! 3 times more than a cheetah!
3, the eagle's grip ability is very strong.
Eagles have a very strong grip, their claws have a special "locking mechanism", eagles hunting claws only need about 25 milliseconds after touching the prey to tighten violently, the sharp claws deep into the body of the prey, at the same time, their claws grip is also very strong, 10 times that of adults, if humans are attacked by eagles, its sharp claws can grasp through human arms.
In short, eagles as birds of prey, they can quickly sprint and subdue prey, mainly composed of the above three factors, and this is also the biological evolution caused by their unique living habits, both achievements, it is not difficult to see the truth of survival of the fittest in nature.
