Which of the following is a sign of a hawk's wellbeing?

Rousing is indeed a positive sign of a hawk's wellbeing. This behavior involves the bird stretching its wings, legs, and body, which helps to increase blood circulation and remove any stiffness. Rousing can also indicate that the bird is comfortable in its environment and is taking the time to engage in normal behaviors that contribute to its physical health and mental stimulation.

In contrast, flapping excessively may indicate agitation or stress, suggesting that the bird may not be feeling secure or may have excess energy. Staying perched for more than 30 minutes could suggest inactivity, which is not always a sign of good health, especially if it reflects lethargy. Not responding to commands can signal a range of issues, such as illness or stress, as healthy birds typically exhibit an alertness to their handler's cues. Thus, rousing stands out as a clear indication of a hawk’s state of wellbeing.
