The size of the Oruzogo mountain gorilla group in the Bwindi Impenetrable Forest, Uganda, now numbers 16 following the recent birth of two babies.

Rangers working to habituate the group to tourists have reported that dominant silverback Tibirikwata fathered both of the infants, with the mothers being named as Birungi and Mutesi. As yet, however, the babies have yet to be given names, with rangers even struggling to determine the sex of the pair as their mothers are keeping them well away from prying eyes.

These latest arrivals makes the group one of the largest living in the World Heritage-listed National Park, home to around half of the last-remaining mountain gorillas in the wild.

Over the past few years, gorilla numbers have been steadily rising, thanks to the work of the Uganda Wildlife Authority and of both local and international NGOs, including the Gorilla Organization.

However, their survival is still being placed in jeopardy by disease, poaching and above all habitat loss. It is hoped that working to attract more tourists to the National Park will provide a sustainable source of income which can be used to secure the long-term future of both Uganda's critically endangered mountain gorillas and of the communities living on the edge of their forest home.
