Barking Sound

Capybaras make a series of short and sharp barks, which are meant to warn other Capybaras of the danger that’s lurking around. Fascinatingly, barking is not always an indication of a real threat.

In addition to warning calls, Capybaras may also bark when establishing dominance over each other. This sound can often be heard during territorial disputes, where Capybaras are vying for control over a particular space or food.
