What does it mean when a hawk rouses?

When a hawk rouses, it means that it stands its feathers on end and shakes them. This behavior is often a part of their daily grooming routine and is essential for maintaining the health and functionality of their feathers. By shaking their feathers, hawks can help to remove dirt, parasites, and debris, as well as distribute natural oils that keep the feathers waterproof and insulate the bird properly. This process also allows the hawk to adjust the positioning of its feathers to ensure optimal aerodynamics while flying.

Rousing is not simply flapping its wings vigorously, which would serve a different purpose related to exercise or flight readiness. It does not involve becoming lethargic; on the contrary, rousing is an active and dynamic movement that signals the hawk is preparing for activity. Additionally, while taking flight into the wind is an important aspect of a hawk's behavior for flight efficiency, it is not related to the act of rousing in terms of feather maintenance and grooming.
