Question:
Why do ducks tuck their bills under their feathers while they sleep? Why do they stand on one leg?


Replies:
An interesting question. The best answer I have found so far is that they reduce exposure of unprotected areas of the body - the bill and feet - by tucking them into feathers. A sleeping bird will occasionally alternate the foot held up. There is some interesting information on the web and in books about level of alertness to danger while sleeping, but not much about the posture. Many other types of birds share these sleeping traits.
