Looking out for the enemy..



Have you ever noticed that even when they have their heads tucked in to sleep ducks keep one eye open. It's called unihemispheric slow-wave sleep.. keeping one half of their brain awake to lookout for predators while allowing the other half to sleep! How about that, and we think we're the most evolved species :) What's better than one duck asleep on a rock.. three ducks asleep on a log :) Taken while walking beside Lake Joondalup. Happy Sunday, take care and stay safe..

  3. Some birds can balance on a branch while asleep as well. And swifts sleep while flying!

  6. I love ducks and didn't know about their eye open sleep. When someone told them to sleep with one eye open, they took it seriously.

  13. It would be useful to shut half your brain as you sleep. I can't really think why though. Perhaps because half of my brain is shut down when I am awake.

  16. Some human's brains can work like that. Think of mothers of small children.

  17. Lovely shots and very interesting information. Maybe I should try that the next time I have insomnia. Half a brain's sleep is better than none!
