In the animal kingdom, mimics(模仿) are not rare. Stick insects pretend to be twigs. Hawk-moth cater pillars resemble poisonous snakes. The examples, though, are visual. Auditory mimicry is rarer, Danilo Russo of the University of Naples Federico II thinks he has found a novel case of it, as he describes in Current Biology. Some bats, he believes, mimic angry bees in order to scare away owls that might otherwise eat them.
Dr. Russo first noticed bat buzzing a few years ago. The noise struck him as similar to the sound of some bees. He wondered whether bat buzzing was a form of mimicry which helped to scare off would-be predators.
To test this idea, he and his colleagues first recorded the buzzing that captured bats made. Then, with protective clothing, they bean the more dangerous task of recording the buzzing made by different bees. Computer analysis revealed that bees’ and bats’ buzzing were, indeed, similar.
Then the researchers recruited several owls. They put the owls, one at a time, in an enclosure with branches for them to stay on, and two boxes with holes in them. They placed a loudspeaker alongside one of the boxes and, after the birds had settled in, broadcast through it five seconds of uninterrupted bat buzzing and a similar amount of insect buzzing three times in a row for each noise. As a control, they broadcast in like manner several non-buzzing sounds made by bats.
During the broadcasts and for five minutes thereafter, they videoed the owls. After analysis, the results were unequivocal. When they heard both the bat buzzing and the bee buzzing, the owls moved as far from the speakers as they could. In contrast, when the non-buzzing bat sounds were played, they crept closer.
Dr. Russo believes this is the first reported case of a mammal using auditory mimicry to scare away a predator. They strongly suspect, however, that it is not unique. Anecdotes suggest s
