Read the passage carefully and do the activities.
Migratory birds are those birds which leave their place of living when the climate becomes uncongenial and migrate to another place.
Sometimes they migrate to another continent and settle there. Some birds leave their abodes in winter and go to another place where the weather is warm.
They do so because it is difficult them to survive in colder regions.
The birds generally eat insects and worms
and during the winter their food becomes
Scarce. Hence they leave the colder places and migrate to warm places. On the other hand, from various hot places the birds move to the cold places of the south.They return to their original place during the spring.
It has also been observed that some groups of the birds migrate from lower regions to higher altitudes. Sometimes they move away from thickly populated areas to the sea shores. It is interesting to note how the birds know about the change in weather and the fact that the becoming weather is not congenial to them.
