Natural History : Arboreal and a sunshine loving snake, active in low bushes and trees at all hours of the day, less active in dull weather. Fast and active in its movements, can dive a good distance from branch to branch. Many speciemens were sighted at different timings, mostly in bright sunshine. Shy and timid in behavior, but bites several times when handled, mild swelling takes place around the site of the bite for half an hour. Mainly feeds on frogs, geckos, lizards and small birds. Many times it enters wooden house roofs in search of geckos, I have seen them in pairs chasing each other in the month of June. Not much known about its breeding biology, juveniles are seen in the month of June. Grows upto 1.3m.
