"White-Cheeked Gibbons"
Gibbons pair for life. In this species males are black with a distinctive crest and white sideburns, females are buff with a black head crest.
These two Gibbons are father and son, sad to say that the mother died several months ago. In the morning when they would first come out the male would sing for his mate, since she died he no longer sings.
Lens: EF 70-200mm f/2.8L IS II USM + 2x
