As of August 2019, my newest nature section, so very few images to begin with.
Colorado or Least Chipmunk (Tamias [or Neotamias] quadrivittatus or minimus)
Chipmunk species are not easy to tell apart. I know that these photos are of one of two species, the Colorado chipmunk or the least chipmunk, because those are the only two species documented for the Sandia Mountains.
Golden-Mantled Ground Squirrel (Callospermophilus lateralis)
According to the Los Alamos Nature Center, "The Golden-mantled Ground Squirrel is similar to a chipmunk with the same overall appearance. However, the ground squirrel lacks the chipmunk’s facial stripes."
Mule Deer (Odocoileus hemionus)
