Nick Allen, a professional opera singer from the UK, performs on cruise ships that visit Antarctica. During a recent trip there, he met a colony of penguins. He gave them a free demonstration of the classical Italian song "O Sole Mio." The penguins, who are clearly uncultured philistines, immediately started running away. The New York Daily News reports:
"You could say they didn't like the sound of his voice," said zoologist Jarod Miller, host of the syndicated TV series "Animal Exploration." "Between his singing and his body language, they likely perceived him as a predator. While they didn’t seem to be fleeing for their lives, they appear to be uncomfortable.” […]
Moving en masse is doing what comes naturally for these beasts, says Miller. “If you’re a flocking or herding animal, you pay attention to your neighbor. So when penguins move, it’s like dominoes.”
