The North American least shrew will also sometimes live inside beehives and eat all the larvae. It will often share its food with other shrews. It eats more than its body weight each day and is known to store food. [4] [7] The North American least shrew makes its home in burrows or shallow runways under flat stones or fallen logs.
The northern short-tailed shrew (Blarina brevicauda) is the largest shrew in the genus Blarina, [3] and occurs in the northeastern region of North America. [4] It is a semifossorial, highly active, and voracious insectivore and is present in a variety of habitats like broadleaved and pine forests among shrubs and hedges as well as grassy river banks.

The American pygmy shrew is the smallest mammal native to North America and is one of the smallest mammals in the world, just slightly larger than the Etruscan shrew of Eurasia. Its body is about 5 cm (2 in) long including a 2-cm-long tail, and it weighs about 2.0 to 4.5 g (0.07 to 0.16 oz). [ 9 ]

The genus Blarina, commonly called short-tailed shrews, is a genus of relatively large shrews with relatively short tails found in North America. Description [ edit ]
The shrew has to eat almost constantly, because they can only survive a few hours without food. [7] Their metabolism drops when they are at rest. McCay and colleagues (1997) found a higher abundance of masked shrews in non-irrigated forests due to a higher availability of larval insects, which is the preferred food source of the masked shrew.
The long-tailed shrew has an unusually limited geographic range. The species can be found in the Appalachian Mountains, Nova Scotia, and Southeastern New Brunswick, from Canada southward along the mountains to North Carolina, and small ranges of the species in Tennessee. In New York, the long-tailed shrew is found in the Adirondacks and Catskills.
Although the marsh shrew and the American water shrew (the two largest shrews in North America) share some features, [4] the American water shrew has more dark-grey-to-black fur on its back, a silver-grey belly and a bi-colored tail [3] and the marsh shrew's fringed hairs are more distinct. [4]
