Napping duck

It amazes me that birds sleep on one leg, with the other leg tucked up against their body. Sleeping standing up seems like it would be hard enough without having to worry about having to balance on one leg. On the other hand, it must be nice to have such a flexible neck to be able to tuck the head in under the wing to keep it nice and warm while sleeping. This photo was taken on the island of Crete in Greece with a fairly long lens, so I was a good distance away from this duck, but based on how he was looking at me, I don’t think he was too happy about me interrupting his nap.
