The Pacific shrew (Sorex pacificus) is a species of mammal in the family Soricidae.

[1] The Pacific Shrew is native to western Oregon, more specifically from the Siltcoos lake to the coast going from the border line of Douglas and Lane counties continuing south to the northern parts of California.

The first documented Pacific shrew to be caught was found at the mouth of the Umpqua River in 1858.

They use the flora to build a nest, gathering small plants such as grass, moss, lichen, or leaves into a pile and pushing themselves into the middle.

In the summer time they have short, red-tinted brown hair, which gets longer and darker moving into the colder seasons.

They will jump into the air to catch flying prey and dig underground after food.

Their prey includes: slugs, snails, earthworms, centipedes, millipedes, scorpions, and various insects.

In all likelihood, their population size has not decreased over twenty five percent over a long period of time.
