Why Migration is Necessary for Some Animals?

Why Migration is Necessary for Some Animals?

Within the animal kingdom, migration is a very essential step that the animals take to adapt themselves to their suitable habitat and to avoid the harshness that the nature throws at them often. It is a seasonal moving from an environment to the other, for the animals to both live and breed and find themselves a less imperfect and more hospital habitat and climate. It is necessary for the birds up in the sky to the fishes in the waters, to the mammals, insects and reptiles on the land. So the mobility takes place through swim, walk and crawl, fly or drift accordingly.

It is clear that this is purely a universal force driven by the nature to sustain and maintain the balance both simultaneously. Even we predict the nature through their movements for we know that birds flying towards south is a sign of climatic changes. Let us look at some marvellous movements in nature:

(1) Arctic Tern: This bird is infamous for its longest migration of 71,000 km. All across from one end to the other of the earth. They travel from Greenland to the Antarctica, crossing both the hemispheres and the poles.
 
(2) Humpback Whales: These giants are the longest migratory animals amongst the mammals. They head from the tropics and reach the north for both, breeding and feeding, covering almost 8-9 kilometres.

(3) Monarch Butterfly: Their migration is a never-ending cycle as they migrate throughout their lives and still are incapable of completion due to their short life span. They travel from Canada to Mexico in months.

The migration when looked closely, is such an awe-inspiring process.
