Migration is an important part of the life of animals and is also necessary for their survival. Insects, birds, fishes, and mammals migrate regularly for an abundance of food water, to avoid extreme cold or heat, for reproduction, and for protection. The author Rashmi Swaroop Johri is a well-known children's writer who has done this book in a very interesting and informative way on various curiosities related to the migration of birds. Hope adults will like it along with kids.
