Adoption by olive baboons (Papio anubis) of newly constructed electricity pylons as sleeping sites in Laikipia, Kenya

Abstract

Abstract Olive baboons (Papio anubis) use fixed, secure, and naturally occurring sleeping sites such as tall trees and rocky cliffs, as protection from predators and often show a selection preference for particular trees or rocky cliff faces. We documented olive baboons' adoption of recently constructed high‐tension electrical transmission towers (pylons) as a novel type of sleeping site in Laikipia, Kenya. The use of pylons suggests that the greatest potential benefits may include reduced parasite exposure and predation avoidance. Thermoregulation and feeding efficiency are not supported as benefits because pylons increase baboons' exposure to wind and cool nighttime temperatures and the pylons were constructed in locations independent of established feeding sites. These observations advance our understanding of olive baboon sleeping site selection in a changing landscape.
