Some sources I'm seeing are disputing the idea that swifts sleep while flying. There hasn't really been very much research on the subject. Might look at http://news.softpedia.com/news/Can-Birds-Sleep-While-in-Flight-74549.shtmlFrom appearances, they do sleep. I'm not confident there's enough evidence to conclusively prove it just yet, however. So far, my impression is that those who know the birds best are not the ones doing the doubting. Despite having had a hip replacement, Mr Overall, 76, regularly scales the ladders which lead to the top of the tower, where the birds nest in boxes behind the ventilation openings.
His knowledge of swifts' lives is encyclopaedic – from their ability to sleep, and even mate, on the wing, to the chicks' ability to endure hunger and cold for far longer than other birds.

That they are not to be violated but with his wrath?" - Thomas Jefferson
