We know that dolphins and bats echolocate, but less is known about the ultrasonic vocalizations of other animals– including the northern short-tailed shrew. Some suggest they don’t even make ultrasonic vocalizations at all, but instead produce noise when they move. In this episode, Valerie Eddington and Laura Kloepper (both currently at University of New Hampshire and previously at St. Mary’s College) discuss their research into the sound made by these creatures.
