Just to update on the chimps, today while I was there the 5 chimps which have been off-show (Boris,Chrissie,Patti,Kiki and Vila) were on-show and had access to island. Kiki did spend some of the afternoon having a grooming session with Patti while Boris and Chrisse tended to stay outside braving the wet weather but all 5 did come out when it dried up a bit. Vila seems to have built a nest near the top which I saw her resting in for most of the day.
:O did you get photos of the five?! If so, gallery!!!!
