Brown Rat Rattus norvegicus Length 30-50cm Familiar rodent with omnivorous diet. Swims and climbs well. Adult recalls an outsized mouse but with a larger, plumper body, shorter ears, shorter legs (but larger feet) and a thicker tail. Fur is coarse and mainly brown, grading to grey on underparts. Tail looks scaly with sparse bristles. Utters agonising screams in distress. First reached in Britain in 1720 as a stowaway on boats. Now widespread and abundant especially in areas where food is discarded.
