This takes me back rather as HK is very similar facially in appearance to her mother N'Pongo. Good news indeed that she has now had the successful birth of Badongo's first offspring.
The last (successful) Gorilla birth was also to this female (HK) but that young female 'Ya Pili' died at around 4 years old. Technically not the last birth as they have said she had one or two more miscarriages since. Hopefully this new baby will turn things around a bit for her now.
Her grown up son 'Mapema' (Ya Kwanza's only surviving offspring), is a breeding male with several offspring, now in Duisburg Zoo.
