Human indeed has developed himself past several years in various disciplines of improving lifestyles. Concerning my blogs so far, we have seen about many buildings and monuments which are built by cement concrete, bricks, rocks, marbles, etc. Can anything think about a construction without these materials?
The answer is definitely a big NO! as the question of strength and durability comes into picture. But there’s someone else who builds a house for himself without these materials and any equipments, without anyone’s help and still much stronger withstanding all weather exposures. Something extraordinary about it’s identification is … It’s not an engineer!
Yes, birds are well best suited in these aspects to build their every nest unique and phenomenal to their species. It’s really an incredible thing to be wondered of having no knowledge of civil engineering, no any education university, no cement, no reinforcement and even no economy. Whenever we think about bird nests, most people may imagine the regular bowl-shaped receptacle of twigs and leaves, but birds nesting behaviours are as diverse as their courting rituals. If you keep your eyes peeled throughout late March and April, you may be able to see evidence of this remarkable workmanship taking place around you.
But how do birds, with only beaks as tools, turn these basic components into nests secure enough to take a growing family of nestlings, vying for their parent’s attentions and stretching their wings?
It would seem that beaks are very good tools for building. The weaver bird starts making a knot with a long blade of grass. Eventually then builds a circular structure, weaving blades using his beak and feet to built a ball-shaped nest. It’s a delicate business of the weaving in new material to create the nest cup.
Hummingbirds are also one of the great wonders in all of nature; so tiny, yet so perfect. This North American creature builds tiny luxurious nests in trees or shrubs, mostly using plant fibers, downy feathers and animal hair, bound together by spider silk.
Hamerkop, an African bird’s nest is a massive, roofed structure set up in the fork of a tree near water. 10,000 twigs, lined with mud for insulation and water-proofing takes months to construct a nest; surprisingly they aren’t satisfied with one, ought to built-up 4 nests every year, working all the year round.
Nest from saliva!!! Edible-nest of Swiftlet is made exclusively out of the bird’s saliva. It is built in layers, usually over protruding rocks on inclined walls of a dark sea cave. Swiftlets nest in colonies of thousands!
The nest of Common Tailorbird is the end-product of ingenious needlework by the bird. Armed with its beak and a silk thread, the tailorbird pierces the edges of a large leaf and stitches them together. It builds its nest in the frame of the arched leaf. The nests are well-camouflaged as they are built among thick foliage.
A less labour-intensive way to make a nest is to use a hole that already exists. Many birds, including owls, take advantage of natural holes in trees as a ready-made place to bring up their young. While, the woodpeckers nest in cavities drilled into living pine trees. It takes years for a breeding pair to excavate one.
