Père David's rock squirrel

provided by wikipedia EN

The Père David's rock squirrel (Sciurotamias davidianus), also known as the Chinese rock squirrel,[2] is a species of rodent in the family Sciuridae. It is endemic to China, where it is found widely in rocky habitats in the eastern and central parts of the country.[1] This largely terrestrial squirrel is overall dull olive-grey with paler underparts, a distinct pale eye-ring and a dark patch on the cheeks. It has sometimes been confused with the rather different –but in colour very variable– Pallas's squirrel; an introduced population in Belgium was first mistakenly identified as Père David's rock squirrel.[3]
