From a scientific point of view, an eagle is a carnivorous bird that belongs to the hawk species. It contains a powerful addition, has long and wide wings, the nose is massive, claws on the feet are bent inward, and on the hips are formed by feathers "pants".
Flight characteristics of an eagle
From the ground it is possible to climb up that a big bird can barely hover over the territory, spreading its wings. However, the "flying" characteristics of the eagle are very impressive. During the "soaring" the eagle has the opportunity to fly at a speed of 190 to 240 km per hour (even when moving on the highway it can not catch up!). Visibility of leisurely movement is formed because of the high altitude of the flight - above 700 meters. And it dives with the outer limits of 320 km per hour, which in general amazes the imagination.
The device of eagle wings with spread "fingers" on the tips guarantees more strong weightless jets from below, than from the top of the wing, and causes the highest lifting power of the bird. For example, the predator is able to roar without moving his wings. And to work with them, only taking off and accelerating during the pursuit of prey. Except for this, its flight is quite stable. The eagle is able to lay its wings a little, leaving the tips scattered, and withstand a smooth flight during a hurricane.
Eagle vision
The eagle has a pretty sharp, wide vision. Any eye of an eagle is able to focus immediately on 2 objects (a person on one), visual acuity allows to see the hare at a distance of more than 3 km, and the peripheral vision it has the ability to embrace 270 degrees. From the height of the flight the eagle is able to see the prey on the plane of 11.5 km. All this is predestined for such a purpose, in order to arrange a bird as an unsurpassed hunter, who knows how to see the prey at a great distance and is able to literally calculate the distance for an attack on it. An interesting precedent: eagles' eyes are locked for 2 centuries: colorless and impenetrable. 1st, absolutely transparent, adapted to counteract prey or strong wind. And the 2nd make it possible to take a nap. Features of hunting
Eagles are effective in hunting. They do not kill useless animals, they catch only for personal nutrition and for chicks. In the presenter are hunting for small game.
Not only do they hunt for food autonomously, but they are also ready to catch fire in the face of honest robbery. For example, they have every chance to take away the prey of a small carnivorous bird on the fly. Eagles hunt for flying birds very well. They catch the victim by surprise, as they hunt from a similar height, because the bird does not actually see them. And then they dive at a similar speed, as the actual prey does not have time to notice them. Slower footage of the eagle fighting with the victim on the fly is fascinating. The eagle can catch birds on the fly and smell the trophy on the fly.
Nest
Eagle's nests are giant nests that are actually built by birds. Eagles erect their own nests on the highest elevation available in the area. For example, they come in order to guarantee protection for the chicks, to own an excellent observation deck and ambush space at the same time, and to soar with the least effort. They expand and complete the nests any year.
Eagles' "families"
Eagles are pretty good birds, they make a couple for life. Some ornithologists have spotted a couple of eagles that have lived together for more than 30 5 years. These birds have an excellent organization of the situation. When the chicks are still absolutely small, the guardians share the household functions. The male is made a breadwinner, and the mother a teacher and a breadwinner. She defends the nest and saturates the chicks, dividing them for prey. Chicks usually hatch 1-2 a year. Through 3 months they grow and already begin to fly on a hunting independently. Sometimes, if the eagle does not make a decision to leave the nest, the guardian sits visavy nests with prey and begins to call the timid baby. Tempting precedents about eagle chicks Telling about the chicks that appear in the families of birds of prey, it is worth noting the proper:
- The testicle hatch mostly eagles, but the male can actively help it in this one, changing if necessary;
- Egg-laying lasts 40-45 days depending on the eagles' appearance;
- Depending on the appearance of the eagle laying has the possibility to consist of 1-3 eggs;
- In case a chick is noticed more than once, the 1st 2 months there is a competitive struggle - more powerful will try to get rid of a brother or sister.
- In case it is not possible to arrange it for 2 months, the world reigns in the nest, the chicks do not conflict anymore;
- In 3 months the attention of the guardians about it stops, the chick is able to hunt independently;
- Maturity comes to the mighty bird only at 4-5 years old.
In antiquity, eagles were considered the emblem of victory and success, and in Egypt and China - the emblem of the sun.
The eagle is present on the coats of arms of many countries around the world, in which the number of Russia.
