Group of rare Cross River gorillas caught on camera in Nigeria

Conservationists hope first known camera-trap images of species are sign of resurgence

Rare images of a group belonging to one of the most endangered gorilla subspecies in the world suggest their numbers could be recovering after decades of persecution, conservationists in Nigeria have said.

Seven Cross River gorillas including infants of varying ages can be seen in the first known camera-trap images of the species, taken in the Mbe mountains in south-east Nigeria by the Wildlife Conservation Society (WCS).
