Common Name: De Winton’s Brown-toothed Shrew

Scientific Name: Sorex durranti

Habitat:

De Winton’s Brown-toothed Shrew is primarily found in the moist environments of the Pacific Northwest, including regions of western Canada and parts of the northwestern United States. This species thrives in subalpine and montane habitats, often inhabiting wet meadows, forested areas, and areas with dense undergrowth.

Physical Characteristics:

This small mammal measures about 6 to 9 centimeters in length, excluding its tail. De Winton’s Brown-toothed Shrew is characterized by its dark brown fur with a lighter underside, providing it concealment in the forest floor. Its most distinctive feature is its brown-tinted teeth, which are a key identification marker of this species.

Behavior:

De Winton’s Brown-toothed Shrew exhibits a variety of behaviors that are typical of shrews. It is primarily nocturnal, foraging for food at night. This shrew is known for its high metabolism, which prompts it to remain active and constantly in search of insect larvae, worms, and other small invertebrates. Notably, it is also highly territorial and communicates through a mix of vocalizations and scent markings.

Diet:

As an insectivorous mammal, De Winton’s Brown-toothed Shrew feeds on a diverse range of small invertebrates, including earthworms, insects, and spiders. This species plays a critical role in the ecosystem by helping control insect populations and serving as a food source for larger predators.

Reproduction:
