Habitat
Trowbridge's shrew primarily inhabits moist coniferous and mixed forests in the Pacific Northwest of North America, from southern British Columbia to northern California. It prefers areas with dense undergrowth, fallen logs, and proximity to streams or wetlands for cover and food sources. This species avoids dry or open habitats, thriving in cool, humid environments.
Diet
Trowbridge's shrew feeds mainly on insects such as beetles, spiders, and earthworms, which it hunts actively in leaf litter and soil. It has a high metabolic rate, requiring it to eat frequently throughout the day and night to sustain its energy. Feeding behavior involves quick, darting movements to capture prey.
Behavior
Trowbridge's shrew is solitary and territorial, marking its home range with scent and aggressively defending it from others of its kind. It is primarily nocturnal, emerging at night to forage in undergrowth, and exhibits rapid, erratic movements due to its high energy needs. This species is known for its vocalizations, including high-pitched squeaks used for communication.
Conservation Status
Trowbridge's shrew is classified as Least Concern by the IUCN, with a stable population trend across its range. Major threats include habitat loss from logging and urban development, though it remains widespread and adaptable.
