To a common disease of enemies – owls, great eared bats (Corynorhinus townsendii) have to emit sounds that cause the buzz of hornets, meeting with the appeal of a listening owl. To that conclusions are attached by interpreters, vozavlyaemye by Professor Danilo rn Eva.

A few years ago, scientists recorded such a strange sensation of bats getting into the Siano River. Then D. Rousseau and his colleagues suggested that animals warn their relatives about the danger in this way, although they do not assume at the same time that this can be a frightening signal addressed to enemies.

To verify the correctness of the second version, 16 captured adults were found in action, objects that they “offered” to listen to a recording of the buzzing of bats, hornets and the usual sounds made by Corynorhinus townsendii.

Scientists noticed that the owls moved away from the speakers at the time of the buzzing of bats, hornets and bees, and, on the contrary, approached the speakers when they heard “normal” sounds.

According to D. Rousseau, this is the first known scientific case when mammals use the so-called Batesian mimicry, in which a harmless species imitates signals that cause a sense of danger in their patients. enemies.
