Movement in our chimp group! (part 3)

After the successful protected contact between our 3 chimpanzees, we rapidly proceeded to the introduction between Homer, Lily and Sanaga inside the indoor enclosure. Introductions always take place inside buildings so that the keepers and the vet could separate the individuals in case of aggression.
 
Lily and Sanaga went out first and were joined a few seconds later by Homer. Hatches to nights cages were let opened to allow a circular movement and give them an escape if needed.
 
The video below shows the introduction. Note the diversity of gestural communication between the chimps.
