Schokar's Bronzeback (Dendrelaphis schokari) is one of the more elegant tree snakes found in South Asia's tropical forests. Slender, fast-moving, and entirely non-venomous, it belongs to the family Colubridae — a large, cosmopolitan group that includes many of the world's most commonly encountered snakes. In Sri Lanka, sightings tend to delight rather than alarm: the species is harmless to people and plays a useful role in forest ecosystems as a mid-level predator.
What does Schokar's Bronzeback look like?
The species is a medium-sized snake, typically reaching between 1.2 and 1.5 metres in length. Its most distinctive feature is the subtle bronze or copper sheen along the dorsal surface — the detail that gives both the common and scientific name their meaning. The base colouration is usually olive-green or brown, which blends naturally with bark and dappled canopy light.
- Head: Slightly flattened with a pointed snout, well suited to threading through branches. The large, rounded eyes are characteristic of an arboreal hunter that relies heavily on vision.
- Flanks: Pale yellowish or cream markings run along the sides, most visible when the snake flattens its body — a defensive posture that also makes it look larger.
- Belly: Pale or white, smooth in texture.
- Tail: Long and tapering, used as a counterbalance and anchor when moving through the canopy.
Where is Schokar's Bronzeback found in Sri Lanka?
The species occurs across a broad arc of South Asia — India, Sri Lanka, Bangladesh, and parts of Myanmar — wherever suitable forested habitat survives. Within Sri Lanka, it is most reliably encountered in the island's wetter lowland and mid-elevation forests. The Sinharaja Forest Reserve, Sri Lanka's UNESCO-listed rainforest in the Southern Lowlands, provides the kind of dense, multi-storey canopy this snake prefers.
It also turns up in secondary forest, forest edges, and well-wooded gardens near larger forest blocks. Like most arboreal reptiles, it is more active during daylight hours, which improves the chances of a chance encounter for patient observers.
What does Schokar's Bronzeback eat?
The species is a generalist carnivore, hunting primarily by sight from a perched or slowly moving position in the canopy. Its recorded prey includes lizards, small frogs, and birds. It will occasionally take smaller snakes, making it an opportunistic rather than specialist predator. Hunting can occur while the snake is suspended from a branch — a strategy that requires both agility and precision striking speed.
As a non-venomous species, it subdues prey through constriction or simply by overpowering smaller animals before swallowing them whole.
How does Schokar's Bronzeback behave in the wild?
This is a diurnal species — active primarily in daylight — which makes it more observable than many of Sri Lanka's nocturnal snakes. When threatened, individuals typically attempt to flee into higher vegetation rather than stand their ground. If cornered, a Schokar's Bronzeback may flatten its body laterally, revealing the paler flank colouration and making itself appear wider than it is — a common bluff display among colubrids.
Despite appearing placid, the species is quick and can move at surprising speed through branches. Observers should keep a respectful distance and avoid handling wild individuals, both for the animal's welfare and to prevent the minor defensive bite that any stressed snake may deliver.
How does Schokar's Bronzeback reproduce?
Like most members of the genus Dendrelaphis, this species is oviparous: females lay clutches of eggs rather than giving birth to live young. Eggs are typically deposited in concealed locations — tree hollows, leaf litter accumulations, or rotting logs — where humidity and temperature remain relatively stable. Incubation lasts several weeks, after which hatchlings emerge as miniature but fully independent versions of the adults, capable of climbing from an early age.
Is Schokar's Bronzeback endangered?
The species is considered relatively rare compared to its more abundant congeners such as the Common Bronzeback (Dendrelaphis tristis). Habitat loss through deforestation remains the principal threat across its range. In Sri Lanka, where roughly 20 percent of the land surface retains forest cover, the species is most secure within formally protected areas and biological corridors connecting them.
Researchers and herpetologists continue to document its distribution, and citizen-science platforms have helped map new locality records in recent years. Photographing and logging sightings through reputable wildlife databases contributes meaningfully to conservation knowledge.
Tips for spotting Schokar's Bronzeback in Sri Lanka
- Focus on the forest edge in the early morning, when snakes bask before the canopy heats up fully.
- Move slowly and scan at mid-canopy height (roughly 2–5 metres), where bronzebacks tend to hunt.
- Look for linear movement across branches rather than a coiled resting shape.
- Wetter, south-western forests such as Sinharaja are more productive than dry-zone habitats.
- A local guide dramatically improves sighting success — trained eyes locate cryptic species that most visitors walk straight past.
Which Sri Lankan forests offer the best wildlife-watching opportunities?
For anyone combining reptile-watching with broader wildlife interests, Sri Lanka's protected forest network offers varied habitats. The Horton Plains National Park in the central highlands harbours a different suite of endemic species at higher elevations, while the Makandawa Rainforest near Kithulgala provides accessible lowland rainforest with good canopy diversity. The Wilpattu National Park in the north-west, though best known for leopard and sloth bear, also supports a rich reptile community across its woodland habitats.
Planning a wildlife-focused itinerary around one or more of these sites gives the best chance of encountering the full range of Sri Lanka's herpetofauna, including the more elusive arboreal specialists like Schokar's Bronzeback.
