Migration in mammals occurs for various reasons such as following food sources or more favorable living conditions. Some key mammal migrations discussed in the document include wildebeest in the Serengeti that travel nearly 3,000km annually following rains, bearded pigs in Southeast Asia that may travel up to 600km following seasonal fruit supplies, and caribou in Canada and Alaska with the Porcupine herd traveling 640km between summer and winter ranges. The document also briefly outlines migrations of white-eared kob, Burchell's zebra, straw-colored bats, Asian elephants, chiru antelope, lemmings, and saiga antelope.

3. Migration:-
Def:
Animal migration is the relatively long-distance
movement of individual animals, usually on a
seasonal basis. ... It is found in all
major animalgroups, including birds, mammals,
fish, reptiles, amphibians, insects, and
crustaceans.

5. Why Mammals Migrate:
Reasons to Move. Some animals travel relatively short
distances to find food or more favorable living or
breeding conditions.
Most animals that migrate do so to find food or more
livable conditions.
Some animals migrate to breed. The Atlantic Salmon
begins its life in a river and migrates downstream to
the ocean.

6. 10 amazing mammal migrations:
Here are some of the world’s most amazing
migrations, from the best-known wildebeest in
the Serengeti to the not so famous bearded pig
in South East Asia – in 1983 the number
migrating through the rainforests of Borneo was
estimated at one million.

7. 1 Wildebeest Serengeti:
Around 1.3 million wildebeest, plus
other antelopes and zebras, travel
nearly 3,000km each year as they
follow the rains around the
Serengeti.

9. 2 Bearded pig South East Asia
Little is known about these odd-looking
pigs’ migrations – but thousands travel
up to 600km, probably following
seasonal fruit supplies.

11. 3 Caribou Canada and Alaska
The 170,000 members of the Porcupine
caribou herd travel 640km between
their summer and winter ranges.

13. 4 White-eared kob South Sudan
Every year, some 800,000 white-
eared kob travel 1,500km through
the Sudd wetlands of South Sudan.

15. 5 Burchell’s zebra Namibia and Botswana
As the crow flies, these zebras travel
500km between Namibia and Botswana
every year. The scale of the migration was
only discovered in 2014.

17. 6 Straw-coloured bat Zambia
At least 10 million bats arrive in Kasanka
National Park from the rainforests of
the Democratic Republic of Congo every
October. It’s possible they travel up to
2,000km.

19. 7 Asian elephant Sri Lanka
It’s not a migration, but the dry-season
merge of up to 300 elephants in Minneriya
National Park, Sri Lanka, is one of the
largest elephant gatherings in the world.

21. 8 Chiru antelope Tibetan Plateau
Herds of up to 1,000 female Tibetan
antelopes can be seen migrating up to
600km between winter ranges and
summer calving grounds

23. 9 Lemming Norway
Lemmings travel huge distances to
find new territory. Many drown, but
by accident, not mass suicide.

25. 10 Saiga antelope Kazakhstan
The saiga travels 1,000km across
the arid steppe of Kazakhstan to
reach the best summer grazing.
