You might have guessed that this record is held by an arctic bird, but can you guess which breed survives in subzero temperatures? The breeding emperor penguin (Aptenodytes forsteri) along the Antarctic Sea can survive in -4 degree Faherenheit, a lower temperature than you'll find any other bird any other bird, according to Guinness. They are able to live there because their flippers and bills are 25 percent smaller proportional to their body compared with other penguins.
