Paul Belloni Du Chaillu (July 31, 1831 (disputed) – April 29, 1903) was a French-American traveler, zoologist, and anthropologist.He became famous in the 1860s as the first modern European outsider to confirm the existence of gorillas, and later the Pygmy people of central Africa.
The first scientific description of gorillas dates back to an article by Savage and the naturalist Jeffries Wyman in 1847 in Proceedings of the Boston Society of Natural History, [79] [80] where Troglodytes gorilla is described, now known as the western gorilla. Other species of gorilla were described in the next few years.
Mountain gorillas have been isolated from eastern lowland gorillas for approximately 10,000 years and these two taxa separated from their western counterparts approximately 1.2 to 3 million years ago. [6] The genus was first referenced as Troglodytes in 1847, but renamed to Gorilla in 1852.
Western gorillas are long-lived and may survive for as long as 40 years in the wild. A group's home range may be as large as 30 km 2 (12 sq mi), but is not actively defended. Wild western gorillas are known to use tools. [10] Western gorillas' diets are high in fiber, including leaves, stems, fruit, piths, flowers, bark, invertebrates, and soil.

According to a 2004 report there were only about 5,000 eastern lowland gorillas in the wild, [3] down to fewer than 3,800 in 2016, [4] compared to over 100,000 western lowland gorillas. However, a survey in 2021 gave an estimate of up to 6,800 suggesting the decline was not as bad as feared although they are still facing severe threats. [ 5 ]
It was also found that the gorillas created more day nest during the wet season and reused nesting sites about 35% of the time. It was also found that the mean group size was 4–7 individual, yet the mean nest size at the sites was 12.4 nests and the most frequent number of nests was 13, showing some gorillas may have made multiple nests.
