Cinereous Mourner

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Distributed across Colombia, Ecuador, Norway, and Venezuela.

gorilla

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 4 distinct biome types within the Afrotropic biogeographic realm. 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.

Cinereous Mourner

The cinereous mourner (Laniocera hypopyrra) is an unusual passerine bird in the family Tityridae, found throughout Amazonia and adjacent parts of northern South America, including Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, and the Guianas. It inhabits the interior of humid lowland and foothill forest, typically below 1,000 meters elevation, where it forages at middle and upper heights for large insects and occasional small fruits. The adult is a uniformly gray bird with orange-tipped wing coverts that are only visible at close range or in flight. Remarkable for its mimicry behavior, the nestling of the cinereous mourner closely mimics the coloration and slow swaying movements of the Megalopyge moth caterpillar—a toxic and venomous species—providing protection from predators during the vulnerable nestling stage. This constitutes one of the most striking documented cases of Batesian mimicry in a bird. The species is classified as Least Concern by the IUCN, with a large Amazonian range. It is restricted to South America and does not occur in Europe; Norwegian database records are erroneous. The cinereous mourner is typically seen singly or in pairs, and its secretive habits make it easily overlooked despite its relatively wide distribution.

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.
