What is migration and why do animals migrate?
Animal migration is the large-scale movement of a species from one place to another. Most species migrate during specific seasons, in search of food or water, or for mating reasons.

Why do animals migrate from place to place?
Animal Migration. The trigger for the migration may be local climate, local availability of food, or the season of the year. Bird migration is the regular seasonal journey undertaken by many species of birds. Bird movements include those made in response to changes in food availability, habitat or weather.
What kind of animals are involved in mass migration?
A literature survey in 2009 found more than 20 species which engage, or used to engage, in mass migrations. Of these migrations, those of the springbok, black wildebeest, blesbok, scimitar-horned oryx, and kulan have ceased. Migration is important in cetaceans, including whales, dolphins and porpoises.

What animal has the longest migration?
The Arctic Tern earns the No. 1 spot for longest migration of any animal, covering a staggering 44,000 miles in its zig-zagging migratory route each year from Greenland to Antarctica and back again. The longest migration for a mammal is by the gray whale.

How do animals know where to migrate?
Migrating animals navigate by using a variety of different sources of information, as well as by instinct, or genetically inherited knowledge. Some animals use the position of the moon, sun and stars to find their way. Others navigate by sensing the Earth’s magnetic field.
