'Singing' mice -- the ongoing debate of nature vs. nurture

What happened to being "quiet as a mouse"? Researchers have recently shown that, rather than being the silent creatures of popular belief, mice emit ultrasonic calls in a variety of social contexts, and these calls have song-like characteristics. So if mice sing, where do they get their music? Are they born with the songs fully formed in their heads, or do they learn them from their peers? This question is of great interest to scientists as, while many organisms produce genetically regulated vocalizations, only a select few species (such as ourselves) can actually learn these vocalizations. If it turns out that mice can indeed learn new songs, it would provide a very convenient mammalian model of vocal learning.
