Avian Health Network (AHN) is a 501(C)3 headquartered and incorporated in the Commonwealth of Virginia. We are an organization of volunteers with no paid personnel. AHN was founded with the intention of making a positive contribution to the advancement of research, education, prevention, treatment and support groups for avian diseases such as Proventricular Dilatation Disease (PDD). PDD is a wasting type disease that can affect and is fatal in captive and free-ranging birds; especially young birds like African Greys; Macaws and Cockatoos. The symptoms and side effects that have been associated with PPD are varied, its routes are unknown, and its outcome is fatal.
