Kinabalu Squirrel

distribution: This squirrel is found above 300 m in ele-
vation in Sabah and Sarawak (Malaysia) and Kalimantan
(Indonesia).

geographic variation: We do not recognize any subspe-
cies, but other authors recognize C. baluensis baramensis of
Sarawak, which diff ers from C. b. baluensis of Sabah (Malay-
sia) by speckling on both the tail and the body.

conservation: IUCN status—least concern. Population
trend—steady.

habitat: The Kinabalu squirrel occurs in the mountains of

the northwestern part of the island of Borneo, such as at

elevations of 300–1800 m on Mount Kinabalu (Sabah, Malay-

sia), in montane oak (Quercus) and lower cloud forests.

natural history: This squirrel is mostly arboreal, but it

is reported to descend to the ground occasionally.
