I didn't realize chipmunks had such a limited range in California! Explains a lot. It did stand out to me while camping recently that I saw chipmunks rather than golden mantled ground squirrels.
That time I put almost all the chipmunk species in the western USA on one map.
Did you know there’s 1 species of chipmunk in Asia, 1 in eastern USA & >20 in western USA?
(I’m not the crazy one here. The chipmunks are the crazy ones.)
