北极动物在冬天用特殊的皮毛和羽毛来应对寒冷的环境，保持体温和融入周围的环境，让它们度过寒冷的季节。其中包括北极狐、北极兔和雷鸟。它们各自都有独特的适应方法，让它们在冬天生存下来。
One of the best parts of winter is curling up with a blanket and a cup of hot cocoa and watching the snow fall outside, while you stay nice and warm.
But what do animals do when it gets cold?
They don't have blankets, hot cocoa or heated houses like we do.
Well, different animals have different ways of dealing with winter weather.
Some animals migrate, or move to a warmer place for the winter.
And some of them hibernate, or hang out in their cozy dens underground.
They don't come out until it's warm again.
But other animals don't migrate /or/ hibernate, and they manage to live in places with really cold winters.
But how do they do it?
Well, they've come up with a pretty cool way to fit in with their snowy environment.
