What does it mean when a hawk circles you and screams?

When a hawk circles and screams, it may be a sign of territorial behavior or a warning. Hawks are known to be protective of their nesting areas, and their vocalizations can indicate that they perceive a potential threat nearby. This behavior can also signify a call to other hawks or serve as a way to assert dominance in the area. Observing such behavior can suggest that you are in proximity to their territory.
