How do arctic terns prepare for migration?

Answer 1

An arctic tern travels extremely far: about 12,000 miles from the wintering grounds to the breeding grounds. The tern must then fly back to the wintering grounds, so that is another 12,000 miles. Therefore, an arctic tern travels around 24,000 miles a year. That's really far!

Answer 2

The Arctic Tern is famous for it's migration, traveling from its Arctic breeding grounds to the Antarctic and back again each year. Each migration the bird sees 2 summers and is exposed to more sunlight than any other animal on the planet. The Arctic Tern, in an average lifetime (which may be 30 years at the most), will have flown the distance to the moon and back; this is equivalent to about 500,000 miles or 800,000 kilometers.

Answer 3

Not all do, for instance the Ptarmigan does not. Other birds however only come to the arctic for the summer when the food is abundant and leave before the winter when there would be no food in the arctic for them. They fly to more clement climes.

Answer 4

Arctic terns prepare for migration by building up their fat reserves through feeding on fish and other marine life. They also undergo physical changes, such as growing a thicker plumage and increasing their muscle mass. Additionally, they engage in behaviors like group flying exercises to ensure they are in peak condition for their long journey.

Answer 5

maybe to breed or to fish or avoid unfavorable climates.

Answer 6

To prepare for migration they put on fat. They do this by eating a lot before their big journey. This is because while migrating, they lose one-fourth to one-half of their body weight.

Answer 7

because it needs to get home
