LAST week, Kwibi had settled down, but this week the dominant male is making things tough again in Gabon.
The five-year-old gorilla will only let those he is used to being with, such as Howletts' head gorilla keeper Colin Angus, work with him.
"Kwibi is biting new people and bashing them against trees," he said.
All the other gorillas, however, are doing well. Djalta's stomach upset has gone and Ama's hands are slowly getting better.
Mr Angus has been shocked by the number of unseen dangers lurking in the forest of the Bateke Plateau National Park.
He said: "Even the caterpillars are dangerous, you just touch them and you get blisters. We thought at first it was something like this that had caused Ama's hands to swell."
n Although this is the last week of the official Born to be Wild gorilla appeal, this paper will be bringing news of the project's progress as Djalta, Kwibi, Ama, Djaltam, Kiba, Ima and Kido continue to live in the wild.
The direct debit for anyone who wants to help by donating vital cash to the project will continue to be found at www. kentonline.co.uk/gorillas.
