Macaw wasting disease is medically known as Proventricular Dilatation Disease (PDD). It is caused by a virus and can be fatal. Any species of bird is susceptible to the infection including cockatoos, conures, and Asian parrots. The main organ that is affected is the proventriculus or the glandular stomach of birds; nerve damage in the stomach eventually leads to overstretching of the stomach until it is unable to contract normally.

Affected birds suddenly have increased appetites that are followed by continuous weight loss. Their crop is usually hard and enlarged. There is also regurgitation, and undigested food is usually present in their droppings.

Birds get the disease from a contaminated environment or from being in contact with the droppings of infected birds.

Cases of PDD are almost always fatal and even administration of antiviral drugs fail to provide successful results. While a liquid diet may help extend the bird’s life, your North Phoenix, AZ veterinarian may recommend euthanasia. To know more, click this link Raintree Pet Resort & Medical Center.
