Sleeping penguin

Birds do not put their heads under their wings when they sleep, but instead bury the bill into the scapular feathers.

Penguins are the only birds that properly hide the bill under the wing: they can't submerge any part of their head within their scapular feathers, because their feathers are so short.

If you're interested in the sleeping behavior of other creatures, read "Sleep behaviour and sleep postures" at Tetrapod Zoology.

Awesome. That's the photo for September on my wall calendar in my cubicle. Well, not the exact same photo but the same pose.
