Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Cameroon, Congo (Republic), Equatorial Guinea, and Gabon. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Christmas Shearwater

The Christmas shearwater (Puffinus nativitatis) is a medium-sized seabird in the family Procellariidae, distributed across the tropical Pacific Ocean. It is entirely dark — sooty brown to black — with no contrasting pale underparts, distinguishing it from most other shearwaters. The species breeds on tropical Pacific island groups including the Hawaiian Islands, Johnston Atoll, the Phoenix Islands, the Line Islands, and several other central Pacific atolls, nesting in coral rubble, dense vegetation, or rock crevices. Like other shearwaters, it is a pelagic species that spends most of its life at sea, foraging for fish and squid in tropical Pacific waters. Christmas shearwaters fly with stiff, shearwater-style wing beats interspersed with gliding, following wave contours close to the ocean surface. Breeding colonies are vulnerable to introduced predators such as rats and cats, which have severely affected many Pacific seabird colonies. The species is generally considered stable within its extensive oceanic range, though individual island populations can be threatened by predator incursions. Conservation of Pacific island nesting sites through invasive mammal eradication programs has benefited this and many other tropical seabird species.

gorilla

The world's largest primate, western gorillas weigh up to 180 kg and inhabit the tropical and subtropical forests of equatorial Africa. Primarily herbivorous, living in family groups led by a silverback male who protects the troop and mediates social conflicts. Critically Endangered, with populations threatened by deforestation, poaching for bushmeat, and outbreaks of Ebola virus disease.
