There is evidence that a number of shrew species use echolocation. These include the wandering shrew (Sorex vagrans), the common european shrew (Sorex araneus), and the short-tailed shrew (Blarina brevicauda). The shrews emit series of high-pitched squeaks. In contrast to bats, shrew probably use echolocation to investigate their habitat rather than search for food.
