Answer:
a)Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. ... The trigger for the migration may be local climate, local availability of food, the season of the year or for mating reasons.
b)Feathers are unique in the animal kingdom. All birds have them, but only birds have them. ... Muscles are attached to the base of each feather, which allows the bird to move them as needed. When in flight, as a bird flaps its wings down, the feathers move together.
