This dull green snake snake is nocturnal and arboreal, but can often be found on the ground as well.
Range: Thailand-wide. Found in evergreen forests, but also found in housing developments. The first one of this species that I found was on my porch at midnight, using my motorbike to reach higher on the windows for geckos. When I followed it, it climbed a small tree and rested about 2.5 meters high until I left the area. Found in a variety of forest types up to 2,100 meters.
Habitat: Bushes and trees. This snake is an excellent climber.
Active Time? Nocturnal.
Food: Geckos and other lizards appear to be its primary food source, but they will also eat small mammals, birds, eggs, other snakes, and frogs.
Defensive Behavior: I have not seen this snake strike often, they calm down with gentle handling very quickly. Usually, they are very calm.
Venom Toxicity: Weak or none. Rear fanged, and the fangs are small and it is not easy for the snake to get a good grip to chew in the venom. That said, at least one instance of significant envenomation has been recorded. Don’t attempt to hand-hold a snake that is biting.
Offspring: Nothing is known about this area.
Notes: These are great snakes for first-time snake hobbyists to handle for a short time in the wild. If they are striking initially, they quickly calm down when held for a short time. There is a very real danger of misidentification of a small non-venomous B. cyanea with one of the venomous green vipers.
Scientific classification: Boiga cyanea
Species: B. cyanea
Binomial name: Boiga cyanea
