The Cantankerous Meadow Mouse

Spotted by the children this weekend in Truckee:
 
Stella's Mountain Jay
Red Tailed Hawk
Sierra White Tailed Jack Rabbit
Tahoe Chipmunk
Sierra Least Weasel
American Robin
Grey Squirrel
Douglas Squirrel
Mule Deer
misc. crickets, bees, ants
and one Cantankerous Meadow Mouse (well, it could have been any of the other twenty or so species of mouse known to live in the Sierras, but it was near a marsh (where said mouse is known to hang out) and it's the one I'd most like to see.  Given the mouse, though, I suppose that feeling wouldn't be reciprocal).
