Buller's chipmunk

Buller's chipmunk (Neotamias bulleri) is a chipmunk, a small ground-dwelling rodent in the family Sciuridae, the family that also holds the tree squirrels, ground squirrels and flying squirrels. It is placed in the genus Neotamias and is endemic to Mexico, so it is found nowhere else in the world. The Wikipedia article this entry is built on is only a stub, which gives its identity, family and range but nothing about its appearance, behaviour or diet, so none of those are described here. Chipmunks of this genus are mostly known from western North America, which makes this Mexican species a southern outlier worth recording.
