Merriam's ground squirrel (''Urocitellus canus'') is a species of rodent in the family Sciuridae. It occurs in the states of Idaho, Nevada, and Oregon in the United States.〔 ==Description== Merriam's ground squirrel is a small, grey, ground squirrel with a relatively nondescript appearance. Adults range from in head-body length, with a tail. Although their weight varies throughout the year, depending on nutrition, typical adult weights of have been recorded for females, and for males. The fur is short and lacks any distinctive markings such as stripes or spots. It is greyish buff over most of the body, and pale buff to white on the underparts. The tail is relatively short and narrow compared with most other related ground squirrels, and the ears are small. However, it can only be reliably distinguished from Townsend's ground squirrel and the Piute ground squirrel by genetic testing, and, for a long time, these species were not considered to be separate.〔
