Every feather has its place. When they fan their wings and then get them resettled, every feather returns to its assigned placement.
Its no surprise that they're able to endure harsh cold without batting so much as an eyelash. Of course, even if the cold did cause them to bat an eyelash they'd be out of luck - they have none! This is clearly the reason why they've been built to endure the harsh weather.
Its a shame we have eyelashes isn't it? Imagine what we could endure if we didn't have them!
