Nest building in orangutans


Prasetyo, D; Ancrenaz, M; Morrogh-Bernard, H C; Utami Atmoko, S S; Wich, S A; van Schaik, C P (2009). Nest building in orangutans. In: Wich, S A; Utami Atmoko, S S; Mitra Setia, T; van Schaik, C P. Orangutans: geographic variation in behavioral ecology and conservation. New York, US: Oxford University Press, 269-277.

Abstract

Orangutans, like the other great apes, build nests ever day. Nests probably serve to achieve the optimum combination of physical comfort, temperature, and safety against predators and parasites. The chapter describes the basic nest-building technique used by orangutans, and draws attention to various special additions to this basic design, whose presence varies geographically. When nesting during the day, orangutans are more likely to use existing nests, or rebuild existing ones, and when building a new nest, do so much faster than when nesting for the night. Orangutans readily build day nests in fruiting trees, but strongly avoid building night nests in them at most sites. Instead, they build their night nests in a selected range of species, which are often not the most frequently encountered in the forest. What features of the trees causes this striking selectivity remains unclear. Similarly, orangutans build their nests in a variety of structural positions in the tree, and there is no good explanation for the geographic variation in the distribution of positions found among sites.
