Placing the base of the trunk, or the head, against a fallen tree and, using the entire body to push against it, rolling it over and away, so as to expose the longer, greener grass and forbs that have grown in its shade. This behavior is seen more frequently in the dry season, when long, green grass is scarce, and in places where elephants have previously felled medium-sized trees. Roll-Tree is predominantly observed by adults due to the strength required to move the fallen trees.
Despite her young age Knubben shows she is an expert at rolling trees and exposing long green grass. (Maasai Mara, Kenya)
