Do penguins fall over when they look up at the sky to watch planes and helicopters fly
over their heads?
Finally, a serious scientific study shows us the answer. Penguins may waddle away
because they dislike the noise. But they definitely do not lose their balance and fall
over. Cartoonists and comedians love to show penguins as having a lack of balance, but
they really do not.
There have been many rumors about penguins falling over since British plane and
helicopter pilots returned from the 1982 Falklands War. They claimed that their flights
had knocked over penguins on the ground.
Falling penguins are a favorite topic for cartoonists and penguin jokes. Environmental
research scientist Richard Stone spent five weeks (watch/ to watch/ watching)
helicopters fly over two King Penguin colonies in the Antarctic. He studied the effects
of the helicopters on the penguins. Stone watched over 1,000 birds, but the penguins
did not have the balance problems that are seen in penguin cartoons and heard in
penguin jokes.
“We saw birds moving away from the noise of helicopters and planes, but not a single
bird fell over after 17 flights,” he said.
Stone explained that the birds became quiet when the helicopters approached. “They
didn’t appear to turn around and look,” he said.
The famous scientific journal Nature explains that balance problems are not the reason
why penguins waddle. When penguins walk in this awkward-looking way, they actually
use much less energy than if they walked “normal-ly.” It helps them to save energy in
the cold Antarctic.
