According to research, these vocalizations were not random but songs, as commented Timothy Holy, one of the researchers. "There was a pattern, sounded like birds singing."

To demonstrate, the scientists reported sound recordings, adapted to the human ear. "It really sounds like the chirping of birds."

To qualify as singing, the sounds should have two main Characteristics:

- A syllabic diversity it means that a multitude of different sounds.
- A temporal regularity, like a chord melody becomes.

During the research the scientists analyzed a group of 750 syllables produced by a single male mouse for a period of 210 seconds and concluded that the animal producing these sounds following a parting and not random.

These are added to the list of creatures that sing in the presence of a member of the opposite sex, birds, whales, insects and possibly bats, and of course the man.
