Ahaetulla dispar

Günther's vine snake is a tree snake endemic to the Western Ghats, primarily restricted to the shola forests of the southern Western Ghats, where it is found in high-elevation montane grasslands and low shrub belts. It occurs only above 1,300 m, up to 2,695 m. The snout is pointed and projecting without a skin appendage, the scales are in 15 rows, and the total length is about 26 inches. Males are often green and females brown (Wikipedia, general species account).

It is active by day, partly arboreal and sometimes on the ground, often found in low bushes or on rocks. It mainly feeds on lizards and frogs, and is presumed to give birth to live young.
