How do gorillas sleep?

Gorillas sleep in nests, which they build on the ground or in trees, depending on various variables, such as the vegetation and the security situation. Every evening mountain gorillas construct a new nest, even if it is only a few metres from the nest they used the night before. Each animal builds its own nest; only infants sleep in the same nest as their mothers. About half an hour before it gets dark the gorillas settle in the nest. Occasionally, they also build nests for the midday rest.
