Question

Given is an image of Arctic tern.
The Arctic tern is known because its migration route is the longest of any bird. It flies from the Arctic to_____ yearly?

A. Atlantis
B. Siberia
C. Antarctic
D. Canada

Answer 1

Hint: A small, slender gray-and-white bird with angular wings, the Arctic Tern is well known for its long yearly migration. They have a small round head with a steep forehead and extremely short legs Arctic Terns migrate from pole to pole. Migration is the best time to go looking for an Arctic Tern. An arctic tern soars over Iceland. These small birds have one of the longest annual migrations of any animal on Earth.

Complete answer:
  (A) Atlantis: - According to Kullenberg some of the ArcticTerns moving southwards during the autumn migration somewhere off West Africa branch off in a westerly direction, crossing the Atlantic in the zone of the doldrums and the southeastern trade winds, reaching the coastal waters of South America somewhere in southern Brazil. However, evidence for the existence of this migratory route is only indirect. There are, so far no actual observations of terns migrating along this route.Records of Arctic Terns moving southward in October off Mar Del Plata in Argentina tend to show that however, that an east-west crossing of the Atlantic does take place,but this is probably carried out by only a small number of birds.
(B) Siberia: - The great flight takes place along two, and only two, migratory routes, the first one along the continental shelf of Western Europe and southwards along West Africa Somewhere in eastern Siberia and in northern Alaska migratory divide must have developed, separating populations which migrate to the west from those migrating to the east.
The populations of eastern most Siberia Anti-westernmost Alaska move southwards along the west coast of America and part of them are said to winter in the Humboldt Current of Chile. It is safe to conclude that the m migrants using this western American route usually continue across the rake Strait to the Antarctic zone.
(C) Antarctic:- It has its main breeding range in the Arctic region, where it is known to breed as far north . On the other hand, it winters in the Antarctic region, where it has been recorded as far south It travels from its Arctic breeding grounds to Antarctica where it enjoys the Antarctic summer.
(D):- Canada: - The Arctic Terns breeding in Canada, use the south-west
European -west African migratory route. But anyhow their destination is Antarctica.

Based on the above discussion, (C) is the correct answer.

Note:
The Arctic Tern breeds in the Polar Regions and winters in the Antarctic zone, performing the most extensive migratory movements known in any bird. The crossing of the Antarctic Ocean, a flight of more than 3000 km, forms the most critical part of the long migration The Arctic Tern has the longest migratory flight of any bird. It literally moves from pole to pole. It has its main breeding range in the Arctic region, where it is known to breed as far north as dry land extends. On the other hand, it winters in the Antarctic region, where it has been recorded as far south as 74° S.
