A persistent, prolonged and aggressive follow at a fast walk or run by one individual (usually in musth) after another (usually in musth). A pursuit often follows an escalated contest; when one male has signaled defeat by fleeing the victor initially Runs-After and then Pursues the defeated male for up to several kilometers. An elephant may also engage in Prolonged-Pursuit when seeing off vehicles.
The two males in this short clip are engaged in an Escalated-Contest that lasted for close to four hours. At this stage they have engaged in two bouts of Dueling and this Prolonged-Pursuit takes place before another Dueling bout. The male being pursued is slightly bigger than the broken-tusked pursuer, but the pursuing male has had help from a larger male who has weighed in each time the broken-tusked male appeared to be losing. Note the aggressive posture of the broken-tusked male - he is Ear-Folding and has an Open-Mouth. The fleeing male Looks-Back. (Amboseli, Kenya)
