What symptom indicates that a hawk may have coccidiosis?

A poor appetite is a significant symptom that indicates a hawk may have coccidiosis. This parasitic infection can lead to gastrointestinal issues, which often manifest as a decreased desire to eat. When a bird is infected with coccidia, the condition can cause discomfort, nutritional deficiencies, and overall health decline, making it less likely for the hawk to engage in normal feeding behavior. Recognizing poor appetite as a key indicator can help in early detection and treatment of coccidiosis, ultimately ensuring better health for the hawk.

The other symptoms, such as excess preening, increased activity, and frequent thirst, do not typically correlate with coccidiosis. Excess preening may suggest stress or discomfort but is not specific to this infection. Increased activity can be misleading, as sick birds often become lethargic rather than active. Frequent thirst might occur due to other health issues but is not a primary symptom of coccidiosis specifically.
