The Arctic is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska, Northern Canada, Finland, Greenland, Iceland, Norway, Russia and Sweden.
The Arctic is crucial for lots of reasons. Not just because it’s home to the iconic polar bear, and four million people, but also because it helps keep our world’s climate in balance. Arctic sea ice acts as a huge white reflector at the top of the planet, bouncing some of the sun’s rays back into space helping keep the Earth at an even temperature.
The long cold weather and harsh environmental conditions make the Arctic region as a difficult place to survive life. Still many species of bird are inhabit in the Arctic region. Many Arctic birds migrate to other parts of the world in winter season to escape from chilling climate. Some birds remain in Arctic circle year around. Because the Arctic Winters are so cold, very few birds overwinter at high latitudes, The few that do are the Raven, Rock and Willow Ptarmigan, Ross’ and Ivory Gull, Redpoll, Gyrfalcon, Snowy Owl and the Brunnich’s Guillemot, Little Auk and Black Guillemot, but in years where food is scarce these will sometimes move a good way south.
When the summer arrives that all changes, and the migrants arrive, these are the birds that cannot find food during the Arctic winter but travel north to exploit the summer food resources of insects, fresh underwater greens, insect larvae. Because the birds need to be in the Arctic and with their eggs ready to hatch when the food bonanza starts, they lay on reserves of fat to see them through the lean times when snow is still on the ground but they are nesting. There are around 100 migrant species that breed in the Arctic and some make long journeys to be there, the longest journey being made by the Arctic Tern which breeds in the Arctic and overwinters in Antarctica. A large proportion of the migrants are wetland birds, swans, ducks and geese, waders and shorebirds. The southern arctic has more marshes than the high arctic and so fewer species are found in the very far north.
