It is known that perpetuates the bat to sleep was concerned Borgelha background and her head down in the status fail imitated in more sophisticated aircraft.
The researchers said that after monitoring bat movements in an enclosed space, and have concluded that these mammals plane exploit the excess of the mass of the wings that are heavy in
relation to body size in attachment Borgelha in the roof while the drooping head down, as reported "Reuters".
And bats do that when you sleep in Bishop caves or hanging in trees.
Researchers at Brown University and the US watched two types of bats: the first and second short-tailed fruit eater for a dog-like face.
During the observation, the scientists found that by wing flap folded together and then one of them briefly about the body conveys the weight of the bat body center to allow him to come up with a stroke in the air allow it to somersault in the air and then hung from the ceiling.
Said Sharon Schwartz, a professor of biology University: "The all aircraft animals maneuvered down a deal with the three-dimensional environment. Exploiting bats this unique maneuver every time fly them, because for the Bat require this process redirect the head forward and back to the top of the abdomen down and then cut head down and lift the toes up. "
She added: "People have many opportunities to observe birds and insects in flight during the day but the life of the bat, hiding amid the darkness of the night and whenever we watched the behavior of the bat in the aviation struck by this bird."
