Question

Many birds from Siberia come to India, during winter months, in the search of
a) Warm climate and food
b) Cool climate
c) Water availability
d) None of the above

Answer 1

Hint: Birds travel long distances from their native place to a place which have similar suitable climatic conditions. These birds are known as migratory birds. They usually travel due to change in climatic conditions, availability of food and water, and breeding.

Complete answer: Siberian cranes from Siberia usually come to India looking for a better suitable climatic condition. The climate of Siberia usually gets very cold during the winter season, making it very hard for the birds to survive in such harsh conditions. So, these birds travel to India during the winter season as the winters in India are mild and suitable for them to survive. They usually travel thousands of kilometers to reach here. Here in India, they get abundant food and water available for them. Siberian cranes migrate through large distances by traveling in groups and aligning them according to the magnetic field of the earth. They travel large distances as their homes in the wetlands of Russia usually freeze during winters making them inhabitable. So, they migrate to India or to China. Once the weather here starts to get a little warmer, they return to their native lands.

So, the answer is ‘cool climate’.

Note: Siberian crane is the largest distance traveling bird. They are divided into two groups of eastern birds and the western birds. The eastern population of the birds migrates to China and the western populations migrate to India (Bharatpur). These species of birds have now become endangered and soon they would go extinct as the climatic conditions are not being suitable for their survival.
