Disease Recognition
Recognizing disease in your birds is sometimes obvious; by the time the disease is obvious, it is too late. Therefore, it is very important to know your bird's normal behavior by observing them. The fact is, it's difficult to recognize when your bird is sick, especially in the early phases of illness. Birds are experts at hiding their symptoms of disease; a defense mechanism to insure their survival in the wild. Therefore, they often do not appear ill until their disease state is advanced. A trained eye or ear can recognize the subtle symptoms of early disease.

Signs and Symptoms of Disease
If your birds exhibit any of these signs contact your avian veterinarian or state, federal or local agriculture office:
