The tufted pygmy squirrel (Exilisciurus whiteheadi) is a species of rodent in the family Sciuridae. It is endemic to highland forest in Borneo. The common name of this tiny squirrel refers to its distinctive ear-tufts. Its diet consists mainly of the lichens and mosses which cover the trees it inhabits.[citation needed]
