Nests are those or other structures created by animals for temporary or permanent residence. There are quite a few different creatures in the world that make their own nests: spiders, wasps, squirrels, mice, crocodiles, etc.
Squirrels are one of the famous nest-makers. Another name for the squirrel nest is gayno. These rodents arrange their shelters only in trees. It should be noted that not every squirrel will build a nest, it all depends on the habitat. For example, squirrels living in deciduous forests occupy empty tree hollows, and in conifers they build spherical nests from dry branches. From the inside, the squirrel nest is lined with leaves, moss, wool and grass. The standard size of such nests is about 30 cm. Usually these gains are located in the forks of branches at a height of 7 to 15 m. Males never arrange nests, as this is the prerogative of females. As a rule, one individual has several nests at once, which it changes every 3 days, thus fleeing from parasites.
Nests are arranged not only by squirrels, but also by animals with a funny name - dormouse (garden, hazel, forest). For example, garden dormouse arrange open "houses", settling in abandoned nests of magpies, blackbirds, jays and other birds. These animals build their dwellings on top with twigs, and then round them off. The exit from dormouse nests is usually at the bottom. These animals arrange their own nests at a height of 60 to 120 cm above the ground.
Some animals generally arrange spherical nests. One of these creatures is the baby mouse. She builds her nest on herbaceous plants and undersized bushes. The nest of a baby mouse has a spherical shape, the diameter of which is from 6 to 13 cm. Usually babies arrange their "houses" at a height of 40 to 100 cm above the ground. Such a nest is built from two layers: outer and inner. The outer layer consists of the leaves of the plant on which the nest is actually located, and the inner layer is made of softer material (wool, grass, etc.). It is curious that in the dwellings of baby mice there is no entrance at all. Climbing inside, the females gnaw a new hole every time, and when they leave, they always close it up. Basically, such nests are intended for breeding.
Reptiles also build nests. For example, alligators build "houses" from a heap of plant debris. They bury their eggs in these nests. It is curious that Nile crocodiles generally arrange a nest of sand, which is a real incubator for their eggs.
Spiders build nests too. For example, tropical representatives of the order of arachnids araneus arrange collective nests in which several breeding females live. Such dwellings are also arranged by insects. For example, in a pill wasp, the nest looks like a jug, and a thorn-nosed wasp generally makes a “house” that looks like a crooked horn.
