Scientists have discovered the secret that birds can fly over long distances. During the flight, the birds were found to take a nap.
At night, however, birds are converted to other brain modes called shortwave sleep (SWS). This mode lasts for several minutes at a time. Interestingly, the researchers found that sleep mode during flight could occur simultaneously on both sides of the avian hemisphere.
In addition, the researchers observed that when the bird was in a rising air, it made a circle and that the hemisphere of the brain associated with the eye close to the direction of rotation was awake. I keep seeing with one eye and turning. Because of this, they do not dive into the water without crashing or planning in the air.
The researchers studied the interesting behavior of birds by fitting a customized device to measure brain activity in the galleys of the Galapagos Islands. The handheld device has installed GPS to track the flight of birds about 1,800 miles for 10 days.
A warship is not the only species that does this. Similarly, mallards, falcons, black birds, sparrows, and other birds also have this flight characteristic.
