How can you tell if a mountain lion is feeling threatened or aggressive?

A mountain lion exhibiting aggressive or threatened behavior can often be identified by its body language, especially the position of its ears. When a mountain lion lays its ears back against its head, it is typically indicating that it feels threatened or is preparing to defend itself. This stance is a clear signal of alarm or aggression, as the animal is trying to make itself appear smaller and less of a target while also preparing to react if necessary.

In contrast, a mountain lion that is lying still may not necessarily be aggressive; it could simply be resting or stalking prey. Grooming itself usually suggests relaxation and is not an indication of aggression. A swaying tail can be seen in various contexts and does not specifically signal that the animal is feeling threatened. Understanding these subtle signs is crucial for safely interacting with wildlife and recognizing when an animal may pose a danger.
