Chilling out on World Penguin Day. World Penguin Day

Penguins are pretty amazing. From their social personalities to their impressive talent for swimming and diving, they're a bird worth celebrating. Today, World Penguin Day, is the perfect time to learn more about these flightless birds, noted for their swimming prowess.

Native to the land and surrounding waters of Antarctica, Adélie penguins migrate an average of 8,000 miles annually, as they follow the sun from their breeding colonies to winter foraging grounds and back again. The species is easy to recognize by the white rings around their eyes. Oh, and if you think you were chilly this winter, these birds thrive in temperatures as low as -20 degrees Fahrenheit.
