English: Daudin's Bronzeback

Dendrelaphis tristis (bronzeback or Daudin's bronzeback) is a species of tree-snake found in South Asia.

Description
Dendrelaphis tristis is a long, slender snake with a pointed head and a bronze coloured line running right down its back. Its diet includes geckos, birds and occasionally frogs. This harmless snake prefers the tree tops to life on the ground. It is camouflaged (made invisible by means of protective coloring) among the leaves because of its uniform ruddy brown skin. This active snake is restless and quick, both on the ground as well as in the trees. Generally a lively and plucky snake, its disposition varies from one example to another. It is found in southern India and the Himalayan foothills. This oviparous (egg laying animal e.g. birds) snake lays its eggs between September and February. The 6–7 eggs in a clutch, or number of eggs laid at once, hatch 4–6 weeks after laying; that is, they have a gestation period of 4–6 weeks.
