Why do common terns migrate?
After the breeding season, the terns migrate south to spend their winter along the coasts of the tropics and the southern hemisphere in areas including Africa, South America and South-east Asia. They have one of the longest migrations of all birds, with an average round trip of 35,000km each year.
Which bird flies the farthest during migration?
the Arctic Tern
No bird migration list is ever complete without mentioning the record-breaking feats of the Arctic Tern. By far the longest migration known in the animal kingdom, this medium-sized bird travels 90,000 km (55,923 mi) from pole to pole every year — from Greenland in the North to the Weddell Sea in the South.
How long can arctic tern fly without stopping?
The birds fly as far as 6,000 miles without a stop. Robert E. Gill Jr. The researchers reported this February that the Arctic terns flew from Greenland to a region of the Atlantic off the coast of North Africa, where they spent about three weeks.
How do Arctic terns migrate?
Arctic terns migrate to follow the summer sun. Seasons happen because Earth is tilted on its axis while it revolves around the sun. During winter, the Northern Hemisphere is tilted away from the sun’s warming rays. This is why it’s colder during the winter in places north of the Equator, like the United States.
Where do common tern migrate from?

Can birds fly over the ocean?
Many birds fly across the oceans and between continents in groups to follow food, habitat or weather conditions. These great seasonal movements of bird species are known as migrations. The most famous migrants like swallows and arctic terns travel huge distances across the globe.
Which insect has the longest migration?
The longest insect migration was performed by desert locust Schistocerca gregaria. The records of S. gregaria found in many Caribbean islands and parts of the east coast South America during October 1988 indicate that they flew within with a tropical wave pattern for a distance of 4500 km.
Do Arctic terns migrate?
Arctic terns usually migrate over the open ocean, but they have been recorded traveling over land as well. While they often fly low, just over the surface of the water and the crests of waves, they can migrate at altitudes of nearly 10,000 feet. Arctic terns are built for the air.
What happened to the Arctic tern?
Least Concern Extinct About the Arctic tern Arctic terns hold the record for the longest migration of any animal in the world, annually making the journey from the Arctic Circle to the Antarctic Circle. One particularly committed tern made the trip in nearly 60,000 miles, or more than twice the circumference of the planet.
How secure are Arctic terns in the wild?
While the Arctic Tern is currently relatively secure in the wild, it faces growing environmental destruction concerns through climate change and a few other factors. In some areas of the world, such as New England and Greenland, the local populations of Arctic Terns have reduced significantly due to hunting, trade, and exploitation.
What are the Predators of the Arctic tern?
Cats, rats, and hedgehogs are all known predators that wreak havoc on Arctic Tern populations, but their worst predator of all is the American Mink, an invasive species common in its nesting grounds. Other predators that can cause trouble for the Arctic Tern are snakes, raptors, polar bears, and foxes.
