The North American brown lemming (''Lemmus trimucronatus'') is a small North American lemming. Originally called the Siberian brown lemming (''Lemmus sibiricus'') they were later formed into two distinct species. ==Physical characteristics== The lemmings are a brown in colour, with an reddish-brown back and rump, while the head and shoulders are grey. In the winter, the coat becomes longer and greyer. The female averages 12.5 cm (5.7 in) in length and weighs 58 g (2.4 oz), while the male averages 13 cm (5.9 in) and weighs 68 g (2.7 oz). Like other lemmings, it has small ears, short legs and a very short tail. The feet, both the soles and toes, are covered with bristles and are adapted for burrowing.
