Habitat
The Slender shrew inhabits moist coniferous and mixed forests in western North America, from Alaska to California. It prefers areas with dense undergrowth, fallen logs, and proximity to streams or wetlands for cover and food sources. These environments provide the necessary moisture and invertebrates for survival.
Diet
The Slender shrew primarily eats insects, earthworms, and other small invertebrates like spiders and snails. It hunts actively using its keen sense of smell, often foraging in leaf litter or under logs. Due to its high metabolism, it feeds frequently, sometimes every few hours, both day and night.
Behavior
The Slender shrew is solitary and territorial, marking its area with scent and defending it from others. It is primarily nocturnal but may be active during the day, exhibiting rapid movements and a high level of activity to meet its energy needs. These shrews communicate through ultrasonic vocalizations and are known for their aggressive interactions when encountering rivals.
Conservation Status
The IUCN status of the Slender shrew is Least Concern, with a stable population trend; major threats include habitat loss from logging and urbanization.
