Is this a photo of Muke and Bakari? I use to follow them on cam when they were in Cinci and would visit them twice a year. I'm sure many of us would like to know their current condition but Oklahoma City Zoo has nothing on the mother and son, how their move went or photos of them. : (
The rockwork seen here front left appears to be the enclosure barrier. It is better that they not climb it. The police would have to deploy
The exhibit appears in the photo to be large, natural substrate and shady. That's 3 out of 4 right there! Are there any climbing opportunities in another section of the enclosure perhaps?
