Proventricular Dilatation Disease (PDD) is a wasting type disease that can affect and is fatal in captive and free-ranging birds; especially young birds. This disease was first recognized in 1971 and since then has been seen in many species including cockatoos, conures, grey parrots, cockatiels, Eclectus parrots, thick billed Amazons, Blue fronted Amazons, and budgies, as well as macaws. This disease is thought to be caused by a virus and can be passed on to other birds, but not humans. It is also known as Proventricular Dilatation Syndrome, Neuropathic Gastric Dilatation, or Macaw Wasting Disease.
