The American pygmy shrew (''Sorex hoyi'') is a small shrew found in Northern Alaska, Canada and the northern United States down through the Appalachian Mountains. It was first discovered in 1831 by naturalist William Cane in Georgian Bay, Parry Sound. This animal is found in northern coniferous and deciduous forests of North America. It is believed to be the second smallest mammal in the world, but has an extremely large appetite for its size. Due to its fast metabolism, it needs to eat constantly. It digs through moist soils and decaying leaf litter for food. == Description == The American pygmy shrew is the smallest mammal native to North America and is one of the smallest mammals in the world, being just slightly larger than the Etruscan shrew of Eurasia. Its body is about 5 cm (2.0 in) in length including a 2 cm (0.79 in) long tail, and it weighs about 2 to 4.5 g (0.071 to 0.088 oz).〔()〕 Its fur is generally a reddish or grayish brown during the summer months, and a white-gray color during the winter months. The underside is generally a lighter gray. This animal molts about twice a year, once during late summer, and again during the spring months. It has a narrow head with a pointed nose, and whiskers. The eyes are small and well hidden. Their primary senses used for hunting are hearing and smell.
