Assuming "Bird's Fino" is a typo for Bird Flu (Avian Influenza), the symptoms can be varied. In highly pathogenic forms, common symptoms include severe respiratory distress such as gasping, neurological signs like trembling and lack of coordination, watery diarrhea, and sudden death. Pox lesions are caused by the Avipoxvirus. While paralysis can occur, gasping and trembling are very common signs of severe systemic infection.
