is a common shrew
Common shrew. Common shrews are one of Britain's and northern Europe's most abundant small mammals. With an insatiable appetite for insects and worms, these tiny terrors can devour up to their own body weight in a single day. All this eating should wear down their teeth, however, iron in the enamel not only turns them red but adds resistance. Common shrews are a staple of many an owl's diet. When disturbed from the nest, young shrews sometimes follow their mother in caravan fashion, using their flexible snouts to hold on to the tail of the sibling in front.
