Snowy owls can stay cozy in minus 20°F in their home in the northern regions of North America, Europe, and Asia. Their extremely thick feathers make snowies one of the world’s heaviest owls, weighing about as much as three basketballs. Too hot? Snowy owls can hold out their wings away from their bodies and pant to cool down.Listen up! Scientists think barn owls, which live on all continents except Antarctica, might have the best hearing of any bird. Stiff feathers on the bird’s face help funnel sound waves created by prey into its ear canals. Based on the angle at which the sound waves hit its ears, the owl figures out a path to its snack—even in total darkness.Tawny owl chicks have extremely protective parents.
