Scientists find mice sing like birds

A recent study has found that male mice sing like birds when they are in the vicinity of female mice, according to The Express. A study completed by researchers led by Dr. Erich Jarvis of Duke University found that a complex song is sung by male mice who are interested in mating with their female counterparts. Humans are unable to hear the sound as the sound is too high pitched for the human ear to register.

The researchers also found that the song became more complex and difficult to sing for the male mice when they could not see the female stated Kevin Seawright. The researchers believe the smell of the female provided a catalyst that made the male call out for the female using a more and more complex sound. The team then discovered that the introduction of the female saw the song become less complex as the male looked to save energy in a bid to mate with the female.
