Lar Gibbon, ThailandThe lar gibbon, also known as the white-handed gibbon, is an endangered ape from Southeast Asia. They are endangered due to many factors, the most pervasive being the continued loss of their habitat. I photographed this one on the Malay Peninsula of Thailand. He was swinging from that tree while calling to his mate. Nikon D500 with Nikkor 200-400mm lens (at 330mm) ISO 800, f/4 at 1/1600th of a second.
