Lowland Gorillas Napping Lumbar Pillow

This image shows two lowland gorillas napping. All gorillas over three years of age make both day nests for resting and night nests for sleeping. Gorillas form nests by sitting in one place and pulling down and tucking branches, leaves or other vegetation around themselves. Adult males usually nest on the ground. Females may nest on the ground or in trees. Juveniles are more apt to nest in trees. | "Smithsonian" and the Smithsonian logo are registered trademarks owned by Smithsonian Institution
