Alston’s singing mouse (Scotinomys teguina) produces vocalizations that are barely audible to humans. Unlike simple squeaks or chirps, the “songs” of these mice last longer and have multiple notes, and the mice can modulate both the amplitude and the frequency of the calls. Researchers have now found that besides using them to attract mates and repel rivals within their own species, these high-pitched tunes can serve as signals across species, too, helping males protect their turf.
