Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA SCIURIDAE

Scientific Name: Callosciurus caniceps
Species Authority: (Gray, 1842)
Common Name(s):
English Gray-bellied Squirrel

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Duckworth, J.W.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, adapted to human disturbance, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Geographic Range [top]

Range Description: This species is found in Thailand, peninsular Myanmar and Malaysia, and small adjacent islands including Langkawi in the west (Oshida et al. 2001). It is found west of the Mekong and east of the Salween (Moore and Tate 1965). It is likely to occur in the small parts of Lao PDR west of the Mekong but thes have not been surveyed adequately yet (Duckworth et al. 1999). It has also been recorded from Yunnan, China (Smith et al. 2008).

Population [top]

Population: This species was rarely found in a survey conducted by Saiful and Nordin (2004) in Peninsular Malaysia (Weng River sub-catchment). It is common in Kuala Lumpur Parks (W. Duckworth pers. comm.) and in Khao Yai National Park in Thailand (W. Duckworth pers. comm.).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This squirrel is well adapted to the presence of people. It may be found in plantations, cultivated areas, second growth and gardens, as well as forest. In natural habitats it seems to prefer dense dipterocarp forests with thick brushy vegetation. It may be found up to 2,500 m, but is usually found at lower elevations (Smith et al. 2008).
The Gray-bellied Squirrel is normally diurnal and arboreal (Saiful and Nordin 2004), although it sometimes descends to the ground to pick up food, which it then carries into a tree and eats. The diet consists of fruit and some insects. The spherical nest is built on the upper branches of a bush or small tree. The home range is small compared with other arboreal squirrels, and does not change in size seasonally.
It has been suggested that one of the reasons for low densities of this species in Malaysian tropical rain forest is competition from the great variety of other arboreal vertebrates (such as birds, and especially primates) for food, especially fruits and leaves, which are among the food items preferred by squirrels (Saiful and Nordin 2004).
Systems: Terrestrial

Threats [top]

Major Threat(s): The are no major threats to this species.

Conservation Actions [top]

Conservation Actions: Saiful and Nordin (2004) state the need for further comparative study on this species' abundance, density and distribution and its relationship to forest structure or habitat quality, spatially and temporally, in hill dipterocarp forest of Malaysia.
