Instinct is inherent in all living beings, thanks to it many species still inhabit the planet.But each is manifested in its own way: someone through the processes of evolution worsened hearing, someone has mastered the technique of disguise, and someone taught Architectural mastery.Let those who builds himself a hole, as well as consider what otnorki and why they are needed.
Animals helping "Architects»
order to protect themselves and their offspring, many species of animals have learned construction skills.They began to construct for themselves a hole, and their structure can be so confusing that many researchers and to this day can not determine the destiny of some parts.Among the animals are considered to be the most successful builders of beaver, fox, almost all the rodents and the badger.
For example, the holes of ground squirrels have a dozen branches, each of which can be up to 20 meters. In addition, in this underground castle has rooms for relaxation, winter and mini barns for storing supplies.It is not surprising that these animals can be called architects.
What otnorki?
now proceed directly to the very otnorkam or lateral branch hole.This construction serves for many applications, and depending on whether it is someone home, they may vary.But above all, this tunnel is used by animals in situations where there is no opportunity to get into the main passage.Simply put, an escape route - that means otnorok.
otnorkov number could reach more than a dozen, here it is all depends on the animal and how long they dwell in their shelter.The largest number of branches is building a fox, thereby creating escape routes themselves at the approach of danger.
build otnorki What animals?
What otnorki, knows a beaver, because in his house, they always have.Above all, they need to get out in cases when the main passages flooded with water for a long time.By the way, it is considered the best architects of beavers in the animal world, because in addition to the fact that they build their own houses stacked, animals and erect dams and levees, and if necessary break through new channels.
gophers are also well aware of the fact that such otnorki.They have long since learned to use these facilities for their own purposes.So when they start building nests and dig otnorki, but before the end of the work is not adjusted.When winter comes, the main gophers sealed passages, only with the arrival of spring is not always possible to uncork them.And then they simply seize upon the desired otnorok, thereby creating a path to the outside.
