Scientists have studied animal behavior to find out whether they can "joke."
Medianews.az, citing foreign media, reports that in many cases this is simply a form of play and learning. For example, birds and mammals chase each other, hide, and suddenly attack – although this resembles human joking, it actually develops skills necessary for survival.
In some cases, however, behaviors give the impression of "mischief." For example, crows play with objects and follow classmates. Weasels build fake nests to confuse rivals – this is not a joke but a smart tactic.
Researchers believe that some animals may display such behaviors simply for fun and curiosity.
