Your bird’s weight can healthily fluctuate if it is a slight change in weight, but if your pet bird loses more than 10-percent of its body weight, an illness may be the cause.
Malnourished birds may begin to loose a significant amount of weight. Aside from the noticeable weight loss, your bird’s keel bone may become more prominent, indicating unhealthy weight loss.
Sudden weight loss could mean infections such as asperigillus, myobacteriosis, intestinal parasites or cancer.
If your bird experiences a sudden drop in weight, immediate medical attention is needed to determine if an underlying infection is the cause.
Weigh your bird on a regular basis, doing it at the same time of day each time to get a more accurate reading of you bird’s condition. Gram scales as opposed to ounces will allow you to recognize slight changes easier.
