Shrew Spotted at McNary Preserve: Tiny Marvels
Update: 2025-12-07
Description
A tiny shrew, no bigger than a thumb, was spotted at McNary National Wildlife Preserve, sparking interest in these fascinating creatures. With ten species in Washington state, shrews are constantly on the move, even in winter. Unlike other animals, they dont hibernate; instead, they shrink their skulls to conserve energy. These insectivores, with poor eyesight and echolocation abilities, are rarely seen due to their small size and speed. Scientists are studying their shrinking and regrowing brain, hoping to gain insights into human diseases like Alzheimers and multiple sclerosis.
