Question

The longest distance travelled by migratory animal is by
a. Arctic tern
b. Golden plover
c. Locust
d. African wild beast

Answer 1

Hint: The relatively long-distance movement of distinct animals, typically on a seasonal basis is called Animal migration. We can say that the most common form of migration in ecology is animal migration. The animals which migrate from one place to another on a seasonal basis are called a migratory animal. This feature is found in all major animal groups, which include birds, mammals, fish, reptiles, amphibians, insects, and crustaceans.

Complete answer:
- The factors like local climate, local availability of food, the season of the year, or for mating reasons triggers the migration of an animal or a bird.
- In the duration of its migration period, the arctic tern travels the longest distance between the countries of Greenland and Antarctica every year. It is a fact that the arctic tern racks up about 71,000 kilometers during this period
- The distance of 20,000 miles is covered by an American Golden-Plover every year. It is said that its files in a circular route which takes them from breeding grounds on the Arctic tundra of northern Canada and Alaska to the prairies of southern South America and back again.
- The Locust swarms are characteristically in motion and are capable of covering a vast distance. They cover 81km a day.
- Most of the African wild beasts cover a 480-kilometer (300-mile) migration loop.

Hence, the correct answer is option (A).

Note: The family of Laridae includes the Arctic tern (Sterna paradisaea) which is one of the types in class tern. We can say that this species is strongly migratory. Every two summers each year, they migrate along a convoluted route. They go towards the Antarctic coast from its northern breeding grounds for the southern summer and back again about six months later.
