Overview
The Mount Kenya Bush Viper is one of the most geographically restricted members of the genus Atheris, known only from a small number of forest fragments in the central Kenyan highlands near Mount Kenya. Its limited range and ongoing habitat loss make it a species of conservation concern.
Like its relatives, it is arboreal, with a compact body suited to life among dense montane forest vegetation.
How to identify it
- Dark olive, brown, or blackish base color, sometimes with yellow-edged scales
- Keeled scales giving a rough texture, though less pronounced than in the Rough-Scaled Bush Viper
- Broad triangular head, vertical pupils
- Prehensile tail
- Distinguished from other Atheris by its highly restricted Mount Kenya range and darker coloration
Habitat & range
Restricted to a few isolated patches of montane forest at moderate to high elevation surrounding Mount Kenya. Highly habitat-specific and vulnerable to deforestation.
Behavior, diet & reproduction
Nocturnal and arboreal, ambushing frogs and small vertebrates from low branches and shrubs. Reproduces via live birth. Considered rare, with a naturally small population size due to its restricted range.
