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.

세계에서 가장 큰 영장류인 서부고릴라는 체중이 최대 180kg에 달하며 적도 아프리카의 열대 및 아열대 삼림에 서식한다. 주로 초식성이며, 무리를 보호하고 사회적 갈등을 중재하는 실버백 수컷이 이끄는 가족 집단을 이루어 생활한다. 삼림 벌채, 식육용 밀렵, 에볼라 바이러스 발병의 위협으로 인해 심각한 위기(CR) 종으로 지정되었다.
