Distribution

Resident and endemic to the moist forest tracts of the Western Ghats mountain range of India. The species is distributed from about Nashik, Maharashtra, in the north, to the Kanniyakumari and Agasthyamalai hills at the southern tip of the peninsula (8). It ranges in elevation from nearly sea level (e.g., Phansad Wildlife Sanctuary, Maharashtra, Kozhikode, Kerala) to around 1,600 m in the mountains (8, 5, 6). More abundant in the moist forests in the mid-elevation range (between 600 and 1,200 m), with density tending to decrease with elevation (17, 1).

The distributional range area of the species has been variously estimated as 132,610 km² (using grid cell size of 25 km x 25 km, 18), and 229,586 km² (10). However, the area of habitat available for the species is lower with estimates of optimal habitat of 22,452 km² (10) and potential habitat of 43,060 km² (19).

Multiple surveys have recorded the species from a number of locations including protected reserves in the states of Kerala, Tamil Nadu, Karnataka, Goa, and Maharashtra (see Table 2). A single sighting was also reported from the Dangs region of Gujarat (20).
