Soups made from bird nest seems to incredulous. Bird nests are usually made from twigs and other materials which are inedible by humans. But believe it that there are nests made by some birds called Swiftlets, which are used to make soups in China and this soup is amongst one of most expensive food items in the bird.
Swiftlets are very small birds belonging to Collocallini tribe. They are mostly the inhabitants of South Asia and Australia. They live in the seashore caves. Most of these caves in the limestone rocks. The birds use echolocation technique to navigate inside deep and dark caves. They made the nests which stick to the walls of the caves. These nests are cup shaped in which the bird just fits when it sits in the nest.
These nests are not made from ordinary material which other birds use. These are fabricated by the intertwining threads of thick saliva which the male birds secrete. There are multiple layers. The purest and most prized nests are white colored. Though these nest are built by birds for laying down the eggs and breeding, they become the curse for the birds. There are professionals who are engaged in removing the nests from walls of caves.
It is back breaking job. They use the bamboo scaffolding to reach to the ceiling. Secondly all the time, he has to hold the torch for dispelling the darkness. The demand for the nests is so high that the birds are made to work overtime. It is a cruelty really to the birds. When they make their first nest, it is scooped out in no time. The bird, helpless, builds the second nest at the same place immediately and it is also plucked before the birds lay their eggs in it. Third nest is generally spared and birds are allowed to lay egg and rear their children because otherwise there is danger of depletion of their population. But the greed is so much that many unscrupulous one’s do not bother about this and destroy their third nest also.
The nest when immersed in water yields a thick gummy substance. Chinese believe that the soup maintains the skin tone, and reinforces the immune system. It increases the virility. It helps in strengthening the lungs and prevent coughs.
100 gram of dry nest includes about 50 grams of water soluble proteins, roughly about 31 grams of carbohydrate, iron and inorganic salts. It is rich in Potassium and other trace elements which are required in trace amounts but are crucial to overall well being.
Authentic bird’s nest soup is quite popular throughout Asia. It is also extremely expensive; many western restaurants serve a less expensive version consisting of soup with noodles shaped to resemble a bird’s nest.
