The Official site of Virunga National Park, DR Congo, have made a great an interesting job:

They have launched profiles of the Mountain Gorillas of Virunga! A profile includes the gorilla age, sex, parents, offspring, siblings, character, quirks, history… they have tried to be as comprehensive as possible.

Check it out here: http://mountaingorillas.gorilla.cd/.

Send them a nice feedback message, it is really a job worth to do it.
