A small, insectivorous mammal, the common shrew has tiny eyes and a large nose giving it keen sense of smell. Shrews hectively snuffle through the undergrowth for their prey, which includes earthworms, spiders and insect chrysalises. They can be found in most habitats, but prefer woodland and grassland. Active by day and night, they are very territorial and aggressive for their size and can sometimes be heard fighting, their high-pitched squeaks particularly noticeable during the summer. Adults may only live for a year, just long enough to have three or four litters of around six young.
