Polar terns drive polar bears away from their nesting sites. This small bird belongs to the seagulls. Body length 36-43 cm, wingspan 74-84 cm. White in color, with a black cap and a gray mantilla, a forked tail, strongly carved. In spring and summer, the beak turns red. Paws are short, which is why he walks waddling. The Polar tern breeds in the polar regions, on the islands and peninsulas of Northern Europe, Greenland, Siberia, Alaska, Canada. But it winters in the Southern Hemisphere in the subantarctic and Antarctic waters of the Southern Ocean and its surroundings. No, just imagine! From one pole to the other! From polar bears to penguins! Due to these flights between the Arctic and Antarctica, the polar tern observes two summers every year (Arctic and Antarctic) and sees more daylight than any other living creature on Earth.
