The eastern green mamba is an arboreal species, which is mainly found in thickly forested and bush-covered areas of southeastern Africa. Though an arboreal species, it does come down in the pursuit of its prey or to bask under the sun; such instances are pretty rare though. It is also found in coastal scrub, moist Savannah, bamboo growth, and mango plantations. Like all other snakes, the diet of this reptile also consists of birds' eggs, small birds, rodents, frogs, lizards, and small arboreal mammals.
