… Certain birds are said to sleep in mid-flight. 

They do so in short ten-second bursts, 

usually after nightfall. 

The bird is able to switch off one side of its brain in order to rest, 

while the other side continues its 

rhythmic vigilance to avoid crashing into a fellow flier and to watch out for predators. 

A Frigatebird can stay aloft for two whole months 

without touching down on either land or water. 101
