But a bird using USWS could both sleep and navigate at the same time. It also adds to the growing literature about the necessity and nature of sleep in general, even in humans. All of the sleep recorded in the study occurred during the upwards-circling portion of the flight; the birds didn’t sleep at all while gliding down. No animal loves flying – or perhaps just hates being on the ground – quite like the common swift. Membership benefits include one year of Audubon magazine and the latest on birds and their habitats. The following year, it never rested for a full night; over the same period, it stopped for just two hours. common swift (Apus apus), which spend the night on the. The fact that some birds fly continuously during nonbreeding periods indicates that the species may not actually need to land for sleep. Airborne swifts don’t have to worry about predators or diseases and parasites they might find on the ground. But as fliers, the birds are adept and quick, Hedenström says. Using this method, the researchers have been able to ascertain that the birds live for months at a time in the air during the winter months, the period of the year they spend in West Africa after the breeding season in Italy. One of them is the frigate, a bird that has a two-meter-long wing-span and has an ultra-light skeleton, which allows it to soar for hours. A few years ago, Rattenborg discovered that Pectoral Sandpipers can survive and even thrive for weeks with very little sleep, and his decades-old finding about Mallard Ducks' half-brained sleeping patterns inspired research about why people sleep poorly in hotels and other unfamiliar places—because one side of our vigilant brain stays a little awake to keep watch.
