We assessed the distribution and relative abundance of giant squirrels and flying squirrels in the state of Karnataka, India. Two species of giant squirrels, the Indian giant squirrel and the grizzled giant squirrel, and two species of flying squirrel, the large brown flying squirrel and the small Travancore flying squirrel, were found to occur in Karnataka. Indian giant squirrels and large brown flying squirrels were more widely distributed than the other two species. The distributional range included the forests of the Western and Eastern Ghats. However, their distribution was confined only to forests with tall trees. Indian giant squirrels and large brown flying squirrels occur in both deciduous and evergreen forests. Small Travancore flying squirrels occupied high-rainfall evergreen forests on western slopes in the Western Ghats, and the grizzled giant squirrels occupy riverine forests. This report of the small Travancore flying squirrel is the first of this species from Karnataka, and this population is the most northern population of its distributional range. Hunting was found to be a major threat, and influenced the abundance of all species except the grizzled giant squirrel. Hunting was primarily for domestic consumption.
