Physical Description

Species Sorex fumeus

(5.3 - 6.1 in) in total length. The average size range for the remaining three species is 8.8 - 10.4 cm (3.5 - 4.1 in). Color: Generally brown on the back and sides, with a whitish venter . All species are darker overall in the winter months. Other things to look for: The shrews of this genus are similar to one another in appearance . They have long, pointed snouts and small ears which are nearly concealed by fur. Their tails are more than half the length of their head and body

Habitat

The Southeastern Shrew prefers floodplain forests and the borders of swamps . It has also been found in dry upland locations, including fields and pastures. The other four shrews in this genus live in the cool, moist coniferous , hardwood , or mixed forests of the Blue Ridge Mountains. These forests are characterized by heavy leaf litter and moss-covered stumps , rocks, and logs .

Ecology: The smoky shrew is most abundant in damp wooded areas, both in conifer and hardwood habitats . Nest sites are beneath stumps , rotted logs , or rocks (Whitaker, in Wilson and Ruff 1999). Breeding season begins March to August and gestation lasts three weeks. Litter size is two to eight, with an average of five. Up to three litters may be produced each year. Unlike many shrews, this one reaches sexual maturity after its first winter. Diet consists mainly of insects and earthworms; also other inverts. Some small vertebrates and vegetative material may be occasional items. It is active throughout the day and night. [1].
