Habitat
This shrew inhabits moist forests, grasslands, and shrubby areas across eastern North America, from Canada to the southeastern United States. It prefers environments with dense ground cover, such as leaf litter or under logs, and is often found near streams or wetlands. These areas provide both food sources and protection from predators.
Diet
The Northern short-tailed shrew primarily eats insects, earthworms, snails, and other invertebrates, which it hunts actively using its keen sense of smell. It also consumes small amounts of plant material and occasionally small vertebrates. Feeding occurs throughout the day and night due to its high metabolic rate, with individuals consuming up to their body weight in food daily.
Behavior
Northern short-tailed shrews are solitary and territorial, marking their areas with scent and aggressively defending them from intruders. They are primarily nocturnal but may be active during the day, using tunnels and burrows for movement and nesting. Notable behaviors include a venomous bite for subduing prey and a high-pitched vocalization used for communication.
Conservation Status
The IUCN classifies the Northern short-tailed shrew as Least Concern, with a stable population trend. Major threats are minimal, though habitat loss from urbanization could impact local populations.
