Dusky Palm Squirrel (Funambulus obscurus) lives in tropical dry forests across South Asia. It feeds on fruits and seeds. Its conservation status is Vulnerable.
Fascinating facts about the Dusky Palm Squirrel
- The dusky striped squirrel can be found from lowland rainforests up to the highest points of Sri Lanka's wet zone, reaching elevations of about 2400 m. This altitude is unusual for a squirrel on the island and places it in areas where frost may appear in winter. Its presence at such heights is recorded in places like Horton Plains and the highlands of Nuwara Eliya, where dense forest cover persists.
- Weighing between 60 g and 70 g, the dusky striped squirrel is noticeably heavier than its Indian counterpart, which averages about 42 g. This greater mass accompanies a slightly larger body, with a head-and-body length of 11-13 cm and a 10-cm bushy tail. The extra weight and longer, thicker stripes give it a sturdier appearance that helps it navigate both ground and canopy foraging.
- The dusky striped squirrel produces a high-pitched trill of rapid barks that many listeners mistake for a bird's song. This bird-like voice is a constant feature of its forest habitat, echoing through the canopy as the animal moves. When alarmed, it adds a flick of its tail to each call, creating a distinctive warning signal. The same trilling quality is used in territorial displays, where the squirrel may bark continuously from a favoured perch for several minutes.
- The dusky striped squirrel lives almost exclusively in the rainforests of Sri Lanka's southwestern wet zone, an area that receives more rain than any other part of the island. This habitat restriction means the animal is rarely seen outside the dense, moisture-laden forest patches that dominate that region. It is most common where the forest remains continuous, from low-lying rainforests up to the highland woods that still retain heavy canopy cover.
- In 2012 the dusky striped squirrel was finally recognised as a separate species after being split from the Indian Funambulus sublineatus. The Indian population is now called the Nilgiri striped squirrel, while the Sri Lankan form retains the name Funambulus obscurus.
