There it produced a lyrical tune as if it were a bird. A musician named Martha Grim visited the mouse, commented on the impurity of its tones and left, musical standards being high in Detroit. Clark gave the mouse to scientists at the University of Michigan. The scientists confirmed that the mouse could sing and then bred it with laboratory house mice.

Recently, though, Matina Kalcounis-Rueppell, a biologist at the University of North Carolina, Greensboro, revisited the mystery of the singing mouse. And after figuring out how to listen to mice on their own terms, she heard something entirely new.
