10 Amazing Migration of animal

This is the list of world’s most amazing migrations, from the well-known wildebeest in the Serengeti to Red Crab of Christmas Island. Animals migrate in search of food or for nesting or else. Every animal has their own reason to migrate.

Number 1: Sooty shearwaters migration.

According to a study Sooty shearwaters migrate nearly 64,000 kilometers a year, flying from New Zealand to the North Pacific Ocean every summer in search of food. Source: Reference

Number 2: Monarch Butterfly migration.

Monarch butterflies perform annual migrations across North America which have been called "one of the most spectacular natural phenomena in the world". Starting in September and October, eastern/northeastern populations migrate from southern Canada and the United States to overwintering sites in central Mexico where they arrive around November. They start the return trip in March, arriving around July. Monarchs also perform small distance migrations in Australia and New Zealand.

Number 3: Chinook Salmon   migration.

Chinook salmon may spend one to eight years in the ocean (averaging from three to four years) before returning to their home rivers to spawn. The Yukon River has the longest freshwater migration route of any salmon, over 3,000 km from its mouth in the Bering Sea to spawning grounds upstream of Whitehorse, Yukon.

Number 4: Adélie Penguins migration.

Adélie penguins living in the Ross Sea region in Antarctica migrate an average of about 13,000 km during the year as they follow the sun from their breeding colonies to winter foraging grounds and back again. "Follow the sun" means that during the winter the sun doesn't rise south of the Antarctic Circle, but sea ice grows during the winter months and increases for hundreds of miles from the shoreline, and into more northern latitudes, all around Antarctica, so that as long as the penguins live at the edge of the fast ice, there will be sunlight. As the ice recedes in the spring, they remain on the edge of it, until they are once again on the shoreline during a sunnier season. The longest treks have been recorded at 17,600 km.

Number 5: Red Crab of Christmas Island migration.

The Christmas Island red crab is a species of land crab that is endemic to Christmas Island and the Cocos Islands in the Indian Ocean. Although restricted to a relatively small area, it has been estimated that 43.7 million adult red crabs once lived on Christmas Island alone, but the accidental introduction of the yellow crazy ant is believed to have killed about 10–15 million of these in recent years. Christmas Island red crabs are well known for their annual mass migration to the sea to lay their eggs in the ocean.

Number 6: Elephant seal.

Elephant seals migrate in search of food, spending months at sea and often diving deep to forage. They return to their rookeries in winter to breed and give birth. Though both male and female elephant seals spend time at sea, their migration routes and feeding habits differ: Males follow a more consistent route while females vary their routes in pursuit of moving prey.

Number 7: Caribou migration.

Some populations of the North American caribou migrate the farthest of any terrestrial mammal, travelling up to 5,000 km a year, and covering 1,000,000 km2. During the spring migration smaller herds will group together to form larger herds of 50,000 to 500,000 animals.

Number 8:  Bats migration.

Many species of bats move between summer and winter habitats. Some search for more abundant food sources in warmer locations, and others seek ideal habitats for hibernating in winter or raising young in summer. Some bats travel seasonally up to 2,000 or 4,000 km.

Number 9:  Wildebeest Migration.

Wildebeest Migration is one of the world's most spectacular natural events. It is incredible, it is magical, it is indescribable and it is a must! Every year over a million wildebeest, zebra and antelope migrate clockwise around the Serengeti/Masai Mara ecosystem, taking in two different countries and making time for birthing, courting and mating on the way. The migration has to cross the Mara River in the Masai Mara where crocodiles will prey on them. They will be hunted, stalked, and run down by the larger carnivores.

Number 10: Sea Turtle Migration

Most of the sea turtles migrate for foraging and nesting and or warmer waters. Often these migrations take them thousands of miles. The leatherback turtle travels an astounding 10,000 miles or more each year in search of jellyfish, crossing the entire Pacific. Sea turtles nest in tropical and subtropical regions around the globe. Both males and females will migrate to nesting areas to breed, generally in the area where they were born. It is not known exactly how adult turtles are able to navigate to their natal (birth) beaches, however, researchers think they may use a number of clues including ocean currents, the earth's magnetic field, and water chemistry.
