architectural structures play an important role in the life of the city.They can decorate it, or may spoil.Can make to the lives of citizens comfort and convenience, but can not seriously spoil it.It all depends on the skill, taste and an architect.And sometimes, in the pursuit of beauty, they lose sight of the reliability and safety of the structure.You can not say about the brothers our smaller - beavers.That's really who could teach a master class to any builder.And if the refinement of construction of these animals are not different, the complexity, uniqueness and reliability they virtually none.Beavers are among the ten best architects of the animal world.
Residence
Beaver Beavers are classified as rodents.And is the largest of its members in Europe and Asia.Dimensions animal very impressive (for rodents) - they reach a length of meters, and weighs about 35 kg.These animals are in Russia always revered for building talent for perseverance, diligence and strength.Beaver can podgryzt per night, go and clean up of tree branches with a diameter of about half a meter.Logs are the construction of dams and for the construction of housing.
So what a beaver is home?Let's face it.Beaver there, so to speak, three kinds of property: Nora poluhatka and hut.Beavers dig burrows and live in them all summer.Nora chamber width is about one meter.Paul is lined with dry grass and chips.He is always above the water level to twenty centimeters, if the water rises, the owner of the hole raises the floor, putting it another layer of litter.The hole always lead a few turns with the beginning of the water.So the animal can protect themselves from uninvited guests.Second home beaver - a poluhatka.Her beaver builds in the case hole collapsed, and there is no place to build a new, or simply did not want to leave their homes.Poluhatka is an intermediate option between the hut and Nora.The entrance to this home is near the shore, and there where the living chamber is completed by the dome of twigs and grass and mud strengthened.
Architects at the call of nature
But the main dwelling called beaver lodge.By its construction rodent preparing thoroughly.The beaver lodges winters, breed.This house is a big beaver domes of twigs and sticks, held together with mud and earth.The walls of houses so strong that they can not afford to break even bear.We construct a hut in the deepest part of the pond.And it is no coincidence.In winter, the pond can promerznut in shallow places to the bottom.And as the entrance to the dwelling beaver begins underwater, in the case of heavy frosts animals can not get out.Also in the hut has a breathing hole.And in the cold days of the house is steam, it indicates that the owners are at home.The temperature in the hut even in severe frosts plus and animals feel very comfortable.Another architectural wonder which is famous for these amazing animals - dam.These beavers are building in order to maintain a certain level of water near their homes.The construction of dams involved the whole family Bobrinev.As a building material used tree trunks and branches, but if the wood is in short supply, the Beavers dragged everything will find: stones, tires, bottles and so on.These are the beavers - amazing shaggy builders.And they really need our protection to you.
