The rainforests of Cerro Chucantí maintain populations of endangered wildlife, including the Colombian Black Spider Monkey (Ateles fusciceps rufiventris) and Baird´s Tapir (Tapirus bairdii) as well as vulnerable species such as the Giant Anteater (Myrmecophaga tridactyla), Great Curassow (Crax rubra) and Puma (Puma concolor), whose populations are extremely vulnerable to habitat loss, fragmentation, and overhunting. In addition, many species of least concern that are found in Cerro Chucantí represent range extensions or unique phenotypes, including the Beautiful Treerunner (Margarornis bellulus), an endemic race of Russet-crowned Quail-Dove (Geotrygon goldmani oreas), and an undescribed race of the Varied Solitaire (Myadestes coloratus). The cloud forest habitat found near the mountain’s peak also makes the location particularly important for amphibian conservation.
