I took this photo of a peculiar male Northern White-cheeked Gibbon at the Minnesota Zoo. This fellow stared straight at me from his perch which was quite far away. Was it my black and white striped outfit?
Some Facts: This species of Gibbon is sexually dimorphic meaning that males and females have different colorings and sizes from the opposite gender. The males are entirely black with white sideburns and a prominent tuft on their head. Females have a reddish-tan color and lack the cranial tuft of the males. These guys are an endangered species found in Southeast Asia. Some 455 Northern White-cheeked Gibbons were recently discovered living in Pù Mát National Park of Northern Vietnam.
