Geographic range
Where Does the Eastern Green Mamba Live?
Native to the coastal regions of East and Southern Africa, the Eastern Green Mamba thrives in a humid belt extending from Kenya down through Tanzania, Malawi, and Mozambique into the eastern provinces of South Africa. This species is a lowland specialist, rarely found far from the moist influence of the Indian Ocean, though it does follow riverine gallery forests inland into parts of Zimbabwe. It is a true resident of the African tropics, favoring stable, high-rainfall environments over the arid savannas found further west.

Behavior
The Eastern Green Mamba is a shy and reclusive arboreal specialist, spending the vast majority of its life high within the forest canopy or thickets. Unlike its more famous relative, the Black Mamba, this species is hesitant to strike and prefers to flee into dense foliage when disturbed. It is a master of camouflage, blending perfectly with sun-dappled leaves to remain undetected by both predators and prey.
Primarily active during the day (diurnal), these snakes are solitary and rarely venture to the forest floor except to bask in a sun patch or occasionally cross between trees. While they are highly venomous with a potent neurotoxic bite, human encounters are relatively rare due to their preference for heights and their non-aggressive temperament. They are known for their extreme agility, moving through the branches with a fluid, almost weightless grace.

Camera Tips
To capture the Eastern Green Mamba on camera, you must think vertically. Conventional trail cameras mounted at knee height will likely miss this species entirely. Instead, mount your camera 2 to 4 metres high, focusing on thick horizontal branches or 'highways' in the canopy where the snake may traverse between feeding or basking sites. Use a sturdy strap and ensure the camera is angled slightly downward to capture the length of the branch.
Trigger speed is critical for mambas. These snakes move with surprising fluidity and can clear a camera's field of view in a fraction of a second. Set your camera to its fastest possible trigger mode and consider a 'Burst' or 'Multi-Shot' setting. This ensures that even if the snake is moving quickly, you capture several frames to help with positive identification. High-definition video (1080p or higher) is often better than stills for identifying the subtle scale patterns of this species.
Because they are active hunters of birds, placing cameras near active nesting sites or fruiting trees (like wild figs or mangoes) that attract birds can increase your chances of a sighting. However, avoid placing cameras too close to nests to prevent disturbing the birds. The best time for capture is mid-morning when the snakes emerge to bask in the sun to regulate their body temperature. Look for 'sun-breaks'—spots where the sunlight penetrates the canopy and hits a prominent branch.
Safety is paramount when checking your equipment. Always use a long stick to check the immediate area around the camera before reaching for it, as these snakes are perfectly camouflaged and may be resting on the very branch your camera is mounted to. If your camera allows for wireless or Bluetooth image transfer, utilize it to minimize the frequency of physical checks in dense, mamba-prone foliage.
