I would like to read more stories / observations about western gray squirrels, California ground squirrels, Merriam's chipmunks and lodgepole chipmunks.
When do you see them? What time of day? What time of year? Do they hibernate? Estivate?
What are they doing? Climbing trees? Chasing each other? Digging holes?
What do they eat? Do they drink water? How abundant are they?
Do you find them at different elevations? Different habitats, that is, slopes without much vegetation, or in pine forests?
For example, I usually see the Merriam's chipmunk crossing roads and around campgrounds. They used to run up and down the forty stairs it took to reach the bird feeding trays atop of the S. Mt. Hawkins fire lookout. They seemed to fly down, they went so fast, seemingly never touching the stairs. But I never saw them at Vetter Mt. fire lookout. Vetter only has three stairs to reach the deck.
Whereas I see the lodgepole chipmunk scurrying across down logs and in the manzanita bushes in Dawson Saddle / Baden-Powell /Throop Peak area. The lodgepole has more distinct stripes on its back then the Merriam's.
