Do peregrine falcons use body language to communicate?

Yes, peregrine falcons do use body language to communicate. They display various postures and movements, such as wing positioning, head tilting, and vocalizations, to convey their intentions or emotions. For example, a falcon might spread its wings or puff out its chest to assert dominance or attract a mate. These non-verbal cues are crucial for social interactions, especially during courtship and territorial disputes.
