Habitat
The Olympic shrew is endemic to the Olympic Peninsula in Washington State, USA, inhabiting moist coniferous forests and areas with dense undergrowth. It prefers cool, wet environments near streams and in alpine meadows, avoiding drier or open terrains.
Diet
The Olympic shrew primarily feeds on insects like beetles and ants, earthworms, and other invertebrates such as spiders. It hunts actively throughout the day and night due to its high metabolic rate, often consuming food equivalent to its body weight daily.
Behavior
Olympic 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, exhibiting rapid, darting movements while foraging. These shrews have a high metabolic rate, requiring constant feeding and making them vocal with high-pitched squeaks.
Conservation Status
The IUCN Red List classifies the Olympic shrew as Least Concern, with a stable population in its limited range. Major threats include habitat loss from logging and climate change impacts on forest ecosystems.
