Since I know practically nothing of birds in depth, how do they sleep during these extended flights? Or is bird "sleep" something different?

- otterley 13y agoCompletely guessing here, but I suppose it's the same sort of involuntary control you have over your body during sleep that keeps you from wetting yourself or rolling off the bed in the middle of the night.
- Someone 13y agohttp://en.wikipedia.org/wiki/Sleep_(non-human)#Birds http://en.wikipedia.org/wiki/Sleep_(non-human)#Birds: "A peculiarity that birds share with aquatic mammals, and possibly also with certain species of lizards (opinions differ about that last point), is the ability for unihemispheric sleep. That is the ability to sleep with one cerebral hemisphere at a time, while the other hemisphere is awake" In other words: the brain has two CPUs, and they switch off only one at a time.

- baddox 13y agoI was more curious about how they eat and drink during extended flights.
- takluyver 13y agoSwifts catch insects in flight, so food isn't a problem. I think there are species which can extract all the water they need from their food, so they may be able to go without drinking.
- seszett 13y agoSwifts drink in flight, you can often see them flying very close to the surface of water... a bit like water bombers.
