A black gibbon is climbing up a tall fence within an enclosure. The gibbon is in the center of the frame and is mostly visible against the metallic mesh of the fence. The enclosure appears to be outdoors, with green trees and grass visible in the background. A large tree trunk is in the foreground, obscuring some of the view of the enclosure. The gibbon's movements are smooth and agile as it ascends the fence. The lighting suggests it is daytime, possibly overcast.
