How to identify Columbian ground squirrel

The Columbian ground squirrel is a medium-sized rodent with a stocky body and a short tail. At first glance its fur appears inconspicuously grey-brown and mottled, but on the back and flanks it is flecked with light and dark speckles that provide good camouflage on rocky or grassy ground.

The Columbian ground squirrel reaches a length of about 30 centimetres and in summer usually weighs between 350 and 700 grams. Striking features are its short, powerful legs, perfectly suited for digging, as well as the only slightly bushy, black-and-white patterned tail.
