The Tassel-Eared Squirrel, or Alberts Squirrel, lives in the four-corners area of AZ, NM, CO, UT, but is primarily found at the Grand Canyon. In the first book-length natural history of tassel-eared squirrels, Sylvester Allred offers an in-depth exploration of these fascinating animals from a DNA analysis of the six sub-species of tassel-eared squirrels to their complex ecological relationship with the habitat in which they live. This squirrels diet consist of ponderosa pine nuts, so as the pines are threatened, so is this unique, and rather charming squirrel.
