Answer 1

Siberian Crane: They are the long distance migrants and among the cranes, makes one of the longest migrations, the eastern population winters in China and western population in Iran. The central population, once coming to India is extinct. They return to the Arctic tundra around the end of April or beginning of May.

Greater Flamingo: Flamingos are generally non-migratory birds. However, due to changes in the climate and water levels in their breeding areas, flamingo colonies are not always permanent. They migrate mainly at night and prefer to fly with a cloudless sky and favorable tailwinds. They can travel approximately 600 km in one night t about 50 - 60 kph. During the day, they fly at high altitudes to escape the predating by eagles. Most flamingos that leave colony go either Southwest to winter in Spain, or southeast to winter in Tunisia and Turkey.

Ruff: They are migratory and sometimes make huge flocks containing hundreds or thousands of individuals in their winter grounds which include southern and western Europe, Africa, southern Asia and Australia or on the Atlantic and Mediterranean coasts of Europe. Kazakhstan is also a major stopover area for them.

Common Greenshank: They are migratory, breeding in Palaearctic regions and moving south in a broad front, along the coasts and inland to their non-breeding areas. They arrive in Australia in August and numbers increase slowly until September, with larger numbers arriving until November. They normally remain in the same location with some local movements. They move forth again in March or April.

Yellow Wagtail: Settled in Alaska, they migrate annually into other part of the Western Hemisphere but spend their winters in warm regions of southeastern Asia and even Africa probably following the migratory route of their ancestors.

Rosy Pelican: They migrate to India during winters due to availability of food. It breeds from southeastern Europe through Asia and in Africa in swamps and shallow lakes.

Starling: They are native to most of temperate Europe and western Asia. It is resident in southern and western Europe and southwest Asia, while northeastern populations migrate south and west in winter to those regions and also further south to areas where it does not breed in Iberia and north Africa.

Bluethroat: It is a migratory species breeding in wet birch wood or bushy swamps in Europe and Asia with a foothold in western Alaska. It nests in tussocks or low in dense bushes. It winters in north Africa and the Indian subcontinent.

Eurasian Wigeon: These are known to breed only in Europe and Asia, although they are likely to be found breeding in North America eventually. They nest on the ground under dense vegetation.

Long billed pipit: Most of these birds are residents or short distance migrants. A number of subspecies have been created for the populations in Africa, through the Arabian peninsula and south Asia.
