I mistook this for a mouse, but on the computer screen at home it was clear that the ears were too small.
There are two species of shrews in the northern Sierra Nevada that sport brown summer coats and bi-colored tails.
The Wandering or Vagrant shrew (Sorex vagrans) prefers open meadows, while Trowbridge's shrew (Sorex trowbridgii) is found in conifer and mixed deciduous forests.
This hollow tree is in an extensive stand of red fir; so I am assuming we are looking at Trowbridge's shrew.
Shrews don't stay put, and they tend to be found in microhabitats overlooked by most camera trappers.
It's a special occasion when I get a photo of one.
