Olive baboons (Papio anubis) use fixed, secure and
naturally-occurring sleeping sites such as tall trees and rocky cliffs,
as protection from predators. Although these sleeping sites are safe,
they can be limited in availability. We documented olive baboons’ use of
45m tall high-tension electrical pylons (towers) as sleeping sites in
Laikipia, Kenya. These observations suggest that olive baboons may use
anthropic infrastructure for sleeping sites in areas where naturally
occurring cliffs and tall trees are limited.
