Which symptom is associated with apoplexy in hawks?

The symptom associated with apoplexy in hawks is uncontrollable shaking. Apoplexy refers to a sudden and severe condition typically caused by a rupture of blood vessels that can lead to a stroke-like state in birds. This condition often presents with various neurological signs, one of which is tremors or uncontrollable shaking. The shaking indicates a serious disturbance in the hawk's normal neurological function, which is characteristic of apoplexy.

Other symptoms that might be observed in birds experiencing apoplexy can include sudden collapse or a lack of response, but uncontrollable shaking is most notably recognized in this context. Understanding this helps falconers recognize when a hawk might be suffering from serious health issues that require immediate attention.
