Mantled howler monkeys are best known for their deep, booming calls, which can carry for several miles through the rainforest and help neighboring groups avoid unnecessary conflicts. Despite their large size and powerful voices, they spend much of the day resting and feeding on leaves, conserving energy from their relatively low-calorie diet. Nikon Z8 with Nikkor 500mm PF lens, ISO 1400, f/5.6 at 1/320th of a second.
