The two-minute video shows a group of eight Cross River gorillas walking along a path within the forest.
The Cross River gorilla (species name: Gorilla gorilla diehli) is a subspecies of the western gorilla (Gorilla gorilla). They are found on the border between the African countries of Nigeria and Cameroon.
The gorillas are critically endangered, with only about 250 to 300 left on Earth. Loss of habitat and intense human hunting for meat are said to be the primary reasons why the Cross River gorilla has declined in numbers.
In an attempt to help these gorillas grow in numbers, the Cameroon government created the Takamanda National Park, in 2008, which is on the border with Nigeria.
