Researchers estimate gorilla population sizes partly by counting and aging thousands of abandoned nests in forest surveys.
Cross River gorillas construct fresh sleeping nests each evening, often on steep mountain slopes or in low vegetation near rugged terrain. Unlike permanent shelters, these nests are temporary structures made from bent branches and leaves. The behavior reduces parasite buildup and provides flexibility in unpredictable environments. In highland habitats fragmented by farms and villages, nightly relocation lowers detection risk from hunters. Researchers have found nest sites scattered across challenging topography, sometimes far from optimal feeding grounds. The act of rebuilding nightly reflects both instinct and adaptation. It is a ritual of survival repeated thousands of times across a lifetime.

Nest placement in steep terrain demonstrates a tradeoff between comfort and concealment. Sloped sites may offer limited flat space but provide vantage points and reduced human access. Each construction requires energy that could otherwise support growth or reproduction. Over decades, this nightly expenditure accumulates into significant metabolic cost. Yet abandoning the strategy could increase exposure to danger. Their sleeping architecture is therefore both biological necessity and survival tactic shaped by human proximity.
Night nests also serve as ecological footprints. Conservationists track population numbers by counting abandoned nests across forest transects. In remote mountains where sightings are rare, these fragile structures become census markers of existence. A decline in nest density signals trouble long before extinction becomes visible. The image of a leaf-woven bed clinging to a mountainside underscores how precarious their world has become. For a species with fewer than 300 individuals, each nest represents one more day defying disappearance.
