Did you know that male mice sing? According to scientists, male mice sing for many reasons, including for courtship and to show aggression. A new study reports that males change the notes in their songs to more closely match the songs of other males. Scientists record the songs and slow down the recordings to listen to them, because they are too high-pitched for humans to hear.
