No, its Biddy. She frequently drops her lower lip like that. Although you can't see it in this picture she has one very grey/white coloured thigh- it was much more noticeable when she was young- natural or an old injury I wonder.
Bongo arrived at Twycross as a tiny baby in 1965. She grew up together with their nonbreeding male 'Joe' and then much later joined Mamfe's group with the young females Biddy & Eva. By that time she had become a rather 'masculine' female and I doubt Mamfe ever mated her though I don't know. Certainly she has never bred.
