How would you feel if you had to build a new house every year immediately after arriving from a trip that has lasted hundreds of kilometers? What would your attitude be if this new house could only serve you for six or seven months? THAT'S EXACTLY WHAT BIRDS OF ALL KINDS DO EVERY SPRING IN THE NORTHERN REGIONS OF THE EARTH!

They enthusiastically collect different materials to build cozy nests for their young. Driven by their divine instincts and only using their notes as a modeling tool, these birds are starting a fantastic building program.

Those that don't build nests

Of course, not all birds are in the construction business. Some return to the old nests, make the necessary repairs, and then settle there. The other birds don't bother building nests. Among them are sea birds and killdeer. Females species of this kind are content to simply lay their eggs in the ground, where moss and leaves make a sparse nest.The chicks of these birds are born covered and can roam around. Then when they come out of their shell, they dry up under the scorching sun and run away.

The murre is another bird that does not engage in nesting activities. The mother mother has an unusual habit of laying her eggs on sloping ledges. You might think this would be the last place on earth for a bird to breed as there is a risk that it will roll to an overwhelming end below. But the creator of the wall was concerned about this possibility. Guillemot eggs have a superior shape and a hard, chewy shell. How does it all work as protection?

A bird fancier’s experiment while watching the murre answers, He let one of his eggs roll up the hill. He reported that the egg does not roll straight, but twisted like a thorn and remained with its hard shell intact. No egg with this pointy shape rolled over the edge. Only a clever breeder could have imagined the shape of these eggs to keep them secure on the sloping ledges they lie on!

Night owls and black skimmers also save the house construction work. The Night Hawk simply lays its protective colored eggs on bare ground, gravel, the top of a cliff, or even the flat gravel roof of a city building. Climb onto the melted sand and make a small hole to place the eggs. A great way to save work!

Living niche construction

The places where nesting birds settle are as varied as the birds themselves. Even among the same species, nesting sites vary widely.

The Wren family is a notable example. The male begins to build by building a rustic nest. So he goes to another site and creates another. And how it is taken! He will build a rustic nest in all suitable places in his domain. Later, when her friend arrives, he takes her on an inspection tour of these potential nests so that she can choose one that suits her needs. So she keeps throwing sticks and he builds a nest as she wishes.

And what places have Mr. and Mrs. Wren settled in? Studies have found that they use spike holes, cages, fish baskets, clothespins, old shoes, cans, hats, an old car cooler, yes they even fit in a pant leg, even a bathrobe in your pocket. like a swimsuit! This is of course no problem for kings!

Interestingly, the disgusting nests that Ms. Wren refuses were not forgotten. One authority suggests that these nests serve to keep other potential pests from entering the kingdom of kings. Why? Ever since kings formed large families, their food needs were enormous. Therefore, the environment around the kingdom kindergarten and its food supply must be kept away from competition from other hungry families.

Interestingly, the rough drill that Wren rejects is not demolished. An agency suggests that these nests act as a deterrent to other domestic hunters entering the kingdom of kings. Why? Because wrenches form a large family, the need for food is enormous. Therefore, the immediate vicinity of the nursing home and its food supply must be kept out of competition from other starving families.

Let us now consider another relative of this family, cousin Cactus Wren, a desert resident. This man's instinct leads him to place his nest somewhere that does not encourage traffic, but in the thorniest section of the inadequate Cholla cactus. There, its spherical nest is well protected by thorns that look like many swords that are ready to penetrate and cling to and carelessly rub. And another cousin, the troglodyte, makes its nest in the rocks and often uses small stones to create a sidewalk that leads to its entrance. Marsh Wren, another relative, builds his house well camouflaged deep in the swamp vegetation.

The ever-popular spring favorite, the black bird, builds its nests in different places. Use branches or stairs on trees; Shrubs, vines, rose arches, fence posts, stone walls, building corners, bridges, boats and carriages, as well as human-installed shelving. These positions were observed to vary in height from a few to twenty meters above the ground.

Perhaps the strangest nesting site is the wagon, a small aquatic bird that lives year-round in the mountains farthest west of North America. This creature often builds the nest directly under the spray of a waterfall, or sometimes even behind the waterfall, where the only possible access is directly from the waterfall. Either he builds it on the tree roots or in a crack near running water. The right place for a bird that loves to go underwater!

Building materials and forms of housing

Bird nests are fascinating things. Something with them seems to invite you, yes, invite you to take a closer look. Anyone who finds an abandoned one must be amazed by its architecture. Although a nest is woven from primitive materials and held together by clay, this is not a weak proposition as it generally withstands rain and strong winds and remains firmly anchored where it is. was constructed. There you will keep your precious load of eggs safe in all weathers. And to think that a small creature instinctively gathers everything with only its craft as a construction tool!

What are some of the materials that these winged creatures use to build their amazing nurseries? Some of these elements are branches, grass, leaves, bark, feathers, hair and human and horse sludge, which are used as binders and are sometimes strengthened by the bird's saliva. . The inside of the nest, where the eggs rest, is usually lined with soft materials such as moss, cobwebs, cotton, thread and even down from a dryer!

The shell nest, made of grass, leaves and branches, is made of green moss. This bird is mainly about the condition of the moss. It should be kept green to camouflage its nest, more or less spherical in shape and six to six inches in diameter. It is said that these birds sometimes spray drops of water with their wet wings to keep the moss fresh and green when there is not enough moisture on the nest.

Birds of prey build a very interesting nest. Its characteristics are responsible for the name of the bird. A roof made of strips of bark, leaves, grass and other materials is built as an arch over it. The entrance is lateral and not superior. This gives the whole structure the look of an old round oven.

A notable nest is the Baltimore Oriole. Mrs. Oriole uses the beak only as a needle and weaves a pear-shaped bag made of plant fibers, hair, moss, soft rope, thread, etc. at the end of a tall, swaying branch. This nest lives so long that the remains are often attached to the tips of the branches three to four years after it leaves. High quality bird art!

The chimney sweeps build tether-shaped nests in hollow trees or chimneys that look like semicircular shelves. They form them by walking in small branches and joining them with their sticky saliva, which hardens.
