Nice Photo! My favourite Mangabey species and one of my favourite species of Monkey too.
Paignton are doing quite well with their small group with two births(1.1) to date but there is only the one breeding female. The adult on the right in this photo is (I think) the stump-tailed one who is her(non-breeding) mother. The third adult female is a sister of the male so one of those two may have to leave the group at some stage.
