Male Frogs Make the Most of Acoustics

Like a teenager hoping his car stereo will attract the attention of girls, male tree frogs in Borneo appear to take advantage of acoustics to attract mates.

Researchers have found that males of a species of inch-long tree hole frogs tune their high-pitched mating calls to take maximum advantage of the acoustics of the holes in which they live and sing to fe- males.

Frogs placed in artificial holes changed the pitch of their singing to sound attractive to females, according to the study published in this week’s issue of Nature.
