Birds' Amazing Ability: Sleeping While Flying

Moving‍‌‍‍‌‍‌‍‍‌ long distances through migration is a hard task that often pushes the animals' physiological limits. However, the case of birds that can sleep while flying is probably the most amazing one.These birds, which could be referred to as sky sleepers, are able to keep their flight for weeks or even months during their long journeys across oceans and continents. They do not come back to the ground for sleeping; instead, they apply a special sleep pattern that allows them to take very brief sleep periods while still being able to control the flight. Such a remarkable alteration in their physiology helps them to save energy, avoid predators, and continue going in the right direction over vast ‍‌‍‍‌‍‌‍‍‌distances.IPL Auction 2026MI, RR, CSK, KKR: As it happened - How Green became a 'Knight' after intense bidding warIPL Auction: Uncapped players strike gold!

Their peculiar sleeping patterns allow them to avoid landings for extended periods of time.Barn SwallowBarn swallow take brief naps during calm glides, typically during migration. These short breaks keep them steady on extended seasonal treks.GeeseGeese‍‌‍‍‌‍‌‍‍‌ are aware and wise birds that during their long flight at high altitude, they go to sleep, but at the same time, they are in some kind of partial rest. They do not completely turn off but keep some parts of their brain functioning so that they can stick to the formation and react to the wind or change of ‍‌‍‍‌‍‌‍‍‌direction.Great‍‌‍‍‌‍‌‍‍‌ snipesGreat‍‌‍‍‌‍‌‍‍‌ snipes can even take very short naps in the air when they fly thousands of miles without a single stop. They are in a nonstop flight during these long migrations, and a very short rest in the air is the only time they allow themselves to recover a little ‍‌‍‍‌‍‌‍‍‌energy.Bar-tailed‍‌‍‍‌‍‌‍‍‌ godwitsBar-tailed‍‌‍‍‌‍‌‍‍‌ godwits are well-known for their incredible nonstop flights that go from one continent to another, and they do not stop anywhere for the most part.As per the general notion, these amazing journeys are accompanied by the short naps that they take in the little part of their brains, which makes it possible for them to revive themselves and hence, stay in the ‍‌‍‍‌‍‌‍‍‌air.The‍‌‍‍‌‍‌‍‍‌ Arctic ternsThe‍‌‍‍‌‍‌‍‍‌ Arctic terns are known to have one of the longest migrations in the entire animal world when they travel yearly between the polar region of the north and the polar region of the south.It is believed that they take some little sleep breaks in their flights during these long travels.As a matter of fact, short mid-flight naps are the only way in which these birds are capable of making such a journey without stopping for too long, and thus they can have a little recovery in their ‍‌‍‍‌‍‌‍‍‌sleep.AlbatrossesAlbatrosses‍‌‍‍‌‍‌‍‍‌ are able to fly for a very long time, and they can be found flying over seas during a storm for hours without landing.They also take naps on the wing, employing a highly specialised version of unihemispheric sleep whereby the half of the brain that rests is the one that is still ‍‌‍‍‌‍‌‍‍‌awake.Frigatebirds‍‌‍‍‌‍‌‍‍‌Frigatebirds‍‌‍‍‌‍‌‍‍‌ rank as one of the most dramatic cases of birds that can sleep while flying. They are capable of staying in the air for several months continuously over vast seas. In these instances of prolonged slow gliding, they make use of unique sleeping modes which enable them to put one hemisphere of the brain to sleep and keep the other attentive.
