Why are birds now the dominant ones in the skies?

There are many species of eagles, there are 287 species in the world, and 56 species in our country alone. They almost all live by eating the flesh of live or dead animals.

The American vulture, arguably the largest of the eagles, weighs 11 kilograms.

The two wings are spread out and are 3 meters wide; There is also the highest flying Himalayan vulture, which can fly freely over cliffs of more than 7,000 meters.

Another peregrine falcon that flies the fastest.

When it spotted a fast-flying mallard, it could pounce at a speed of 100 meters a second and catch the mallard.

The eagle is indeed the fiercest of the birds, and the eagle owl can catch the beasts on the ground in the blink of an eye, even foxes and wolves cannot escape its claws.

These characteristics cannot be compared to by any bird. Therefore, people call the eagle "the king of birds".

The eagle is the strongest aerial predator that can be seen today, among them the Andes.

Weighing 25 kilograms, the eagle is the largest bird to fly today, the horned eagle has a grip strength comparable to that of a hunting dog, and the peregrine falcon is the fastest flying bird, the kestrel.

Osprey can hover, golden eagle.

Wolves can be killed, and what they have in common are: sharp eyes, sharp claws, and a strong digestive system.

Amazing flying skills, as well as specially constructed feathers.

Because the bones of the bird are very light, it fits the air flow.

The outside of the bird's body is light and warm feathers, the feathers not only have the effect of heat preservation, but also make the bird's appearance streamlined, the least resistance when moving in the air, which is conducive to flying, when flying, the two wings continue to fan up and down, and the air flow will occur, and a huge downward pressure resistance will occur, so that the bird body can fly forward quickly.

He is a flying animal, and this characteristic of it can protect itself, and it is all of human help

The wings of birds are the first condition for them to have flying skills.

Because among the animals that can fly, the number and variety of birds are the largest.

The wings of birds can skillfully use aerodynamics.

Because most of the birds can soar in the sky.

It is a flying animal and can avoid a lot of injuries.

Wings are what they have to do with their flying skills.

Why the pterosaurs are completely extinct! Can birds dominate the sky? So the scientist explains!

Because they're huge.

Birds are the golden eagle, the horned eagle, the ape-eating eagle, and the Andean vulture.

1. Golden eagle. The golden eagle is a well-known bird of prey, and it is also a large bird of prey, the adult golden eagle body length can reach meters-meters, the wingspan can reach 2-meters, the female body size is larger than the male, the golden eagle often dives down at a speed of up to 300 kilometers per hour to give the prey a fatal blow to the head. There are dozens of animals in the golden eagle's diet, including deer, goats, and foxes.

2. Horned carving. The horned eagle, also known as the Harpehawk or Harpy Eagle, is the largest and strongest bird of prey in the Americas and one of the largest eagles in the world, with the average adult female horned eagle reaching a meter in length. This body length can be said to be the longest among birds of prey, but the wingspan of the horned eagle is relatively short, about 2 meters, and the male is generally smaller than the female.

With strong claws almost as large as a human hand, sharp nails up to 12 cm long and a grip of up to 50 kg, it can easily crush the skull of prey and even pierce very thick iron plates. Its recipe is also very rich, which includes sloths, long-nosed raccoons and even pythons.

3. Ape-eating eagle.

The ape-eating eagle is as sleepy as its name, it will prey on monkeys, so it is also known as the monkey-eating eagle, the adult female ape-eating eagle has a body length of 2 meters, and the wingspan can reach 2-meter. Females are likewise larger than males. The recipes of ape-eating eagles include cats, monkeys, bats, snakes, lizards, hornbills, civets, macaques and hares, etc., and even some domestic animals, such as dogs and piglets.

The ape-eating eagle is the national bird of the Philippines, but unfortunately there are fewer than 500 of them left.

4. Andean vulture.

The Andean condor, also known as the Andean eagle, is one of the largest birds of prey in the world, and deservedly the largest bird of prey. Adult Andean vultures are meters long and have a wingspan of up to meters. It is recorded that the largest Andean vulture has a wingspan of 5 meters, and unlike the three sky lords above, the male of the Andean vulture is larger than the female.

Habits of the Andean vulture:

Andean vultures are adept at long-distance flights, covering more than 200 kilometers from the Colca Canyon in Peru to the coast of Panama, leaving early in the morning and returning in the evening, eating only some food such as seal carrion. Good at soaring, it can be raised by the updrafts in the mountains, and fly silently over ravines and rivers.

They can feed on the carcasses of any animal, especially the carcasses of cattle and sheep. Unlike many Old World vultures, Andean vultures rarely feed together in large groups of a few dozen. The Andean vulture is very voracious and will never leave without eating the carcass.

Andean vultures often fly to high cliffs after eating for a long time to "sit" because they eat too much and are too full.

However, their digestive system is muscular and has a strong digestive system, which allows them to digest smoothly even if they eat too much. Because of its strict legal protection, the Andean vulture is more common in the Andes and the Pacific coast of South America.

Known as the "king of birds", the length of the wings can reach 7 meters, the absolute air supremacy, the Argentine giant eagle can weigh up to 150 kilograms, the length of the wings can reach up to 7 meters, they stand on the plane of more than two meters tall, the whole body looks like a small aircraft, it is the largest flying bird in the world, but although they are particularly large, but the predation ability is relatively weak, Because the jaw is not strong enough to tear up large and medium-sized prey, the Argentine giant eagle generally likes to catch some petite animals, and it is worth mentioning that this guy can be described as a lazy terminal cancer patient in the animal world, obviously has the ability to prey on prey, but likes to eat animal carcasses.

I have to say that the Argentine Giant Eagle is really a unique guy, no wonder it is a candidate for the king of birds.

A real air supremacy! Even lions and tigers don't dare to mess with it, what is the origin of this bird?

Birds may have evolved from Jurassic saurosaurs. The earliest birds showed a clear resemblance to the dinosaurs. Birds were greatly developed in the Cretaceous period, and by the beginning of the Cenozoic, there was no significant difference in the structure of modern birds.

It can be speculated that about 200 million years ago, a group of ancient reptiles from the Old World evolved into birds, and gradually expanded to the New World as birds flourished. While adapting to changing environmental conditions, birds have developed adaptive radiation to different lifestyles. Birds are a group of higher vertebrates that evolved from ancient reptiles and adapted to flight.

In addition to many of their morphological structures, they also have many differences from reptiles. On the one hand, these differences are that they have developed greatly on the basis of reptiles, and have a series of progressive characteristics that are higher than reptiles. For example, a high and constant body temperature, a well-developed dual circulation system, a well-developed nervous system and sensory organs, and various complex behaviors associated with this; On the other hand, in order to adapt to the flying life, there are more special lithifications, such as the body is streamlined, the body surface is feathered, the forelimbs are specialized into wings, the bones are strong, light and multi-combined, with air sacs and lungs, air sacs are the structure of the first bird to have enough oxygen when flying.

The contraction and expansion of the airbag are coordinated with the movement of the wings. The wings are raised, the air sacs expand, and a portion of the outside air enters the lungs for gas exchange. In addition, most of the air passes through the lungs directly into the air sacs, and the air bags temporarily store a large amount of oxygenated air without gas exchange.

The wings droop, the air sac contracted, and the air in the air bag passed through the lungs for another gas exchange and finally expelled from the body. In this way, for every 1 breath of birds, the air exchanges gas in the lungs twice, and it can be seen that the air sac does not have the effect of gas exchange, its function is to store air and assist the lungs to complete the respiration function. The airbag also has the effect of reducing the specific gravity of the body, dissipating heat, and regulating body temperature.

This series of characteristics gives birds a very strong ability to fly and can carry out special flight movements.
