When we disagree with someone’s opinion or behaviors, we use our shared language to have a conversation or healthy/unhealthy argument. But what about animals? Apparently, not just intelligent creatures like apes and elephants, birds are also known to have arguments. (Recently even researchers discovered a pair of birds arguing about parental issues.) Especially, parrots are known to be very vocal when it comes to arguments and as they can imitate human language, it is obvious that they would use it as a tool in a discussion.
Take this video below for an instance! These two parrots are having an argument over something. At first it looks it is going smoothly, but seconds later it becomes intense and the parrot on the left even spreads his wings in aggression.
