Singing Mice, Songbirds, and More: Models for FOXP2 Function and Dysfunction in Human Speech and Language
Although the most widely appreciated vocalizations of mice are audible, it has been known for several decades that mice and other rodents also vocalize at ultrasonic frequencies.

When the recordings were computationally shifted into the range of human hearing, these vocalizations were found to be subjectively reminiscent of bird songs.Purrrr for my musical furends, dat mean an electronic capo, sort of.
