Frigate Birds Can Sleep During Flight, Study Finds
Scientists have found birds are capable of sleeping in flight, according to a new study.
Published in the journal Nature Communications, the new study looked at brain activity of frigatebirds that indicated the birds sleep in flight with either one side of their brain at a time or both side at the same time. Despite this ability, the birds in the study slept less than an hour per day, a small percentage of the time they spend sleeping on land.
How frigatebirds are capable of functioning on such little sleep remains a mystery, the researchers said.
