Diseases / symptoms typically seen in African Grey Parrots:

Respiratory Signs, Chronic Depression, Weightloss: Aspergillosis (fungal disease), bacterial infections / pneumonia, nutritional deficiencies (Hypovitaminosis A) (please refer to african grey nutrition), inhaled toxins (please refer to tttt... Sarcocystosis

Weightloss, Undigested Seed in Droppings: PDS / PDD, Macaw Wasting Disease - Terminal disease. Contagious to other birds. Disease pathogen not thought to be airborne. Birds may show neurological signs (seizures, falling off perches, etc.).

Seizures caused by Hypocalcaemia syndrome associated with low calcium levels in the blood. Supplementing the parrots' diet with calcium and Vitamin D, and providing access to natural light are important factors in preventing this problem. Birds aged 2 to 5 are most commonly affected. Vet's often treat grey parrots suffering from seizures presumptively with intravenous calcium gluconate, as well as with diazepam.

• A lot of the health problems associated with low calcium levels can be prevented by providing sufficient natural sunlight to our pets. Even those situated by a window will not benefit from the sun because the window blocks the UVA and UVB rays needed to synthesize vitamin D necessary for bone health. Birds use sunlight by preening their feathers. The substance on the feathers will undergo a chemical reaction from the sunlight producing Vitamin D3 which the bird ingests with further preening of the feathers. The indoor bird does not have the benefit of this reaction.
  • The most common health problems associated with vitamin D deficiency are: weakened immune systems / susceptibility to diseases, soft bones, bent keels, splayed legs, abnormal beak development, reproductive problems (egg binding, soft-shell eggs, dying chicks) as well as seizures and, to a lesser extend, Stargazing (twisted back)
  • In areas where access to natural sunlight is limited (such as in the northern hemisphere during the winter months), full-spectrum lamps can be used to provide UVA and UVB rays.

  Vitamin D / Calcium Deficiency can also be a result of a malfunctioning uropygial gland, as the uropygial or oil gland produces vitamin D3 precursors that are spread into the feathers as the birds preen themselves. Upon exposure to ultraviolet light, the precursors will be converted to active D3, which will then be ingested when the birds preen themselves again. Therefore, it is important to also make sure that the gland is working properly.

Feather Picking / Plucking / Mutilation - can be caused by physical and behaviorial problems. The African Grey is a highly intelligent parrot species that predisposes them to boredom potentially leading to behavioral problems, such as plucking. ... Feather Plucking / Mutilation

Changes in Feather Coloration:

African Greys with red feathers scattered throughout the plumage are occasionally seen. Such red feathers scattered in areas where you wouldn't expect to see them could be an indication of damaged feather follicles (usually because of feather plucking), medication (for example administration of antibiotics at the time a bird is molting has caused changes in feather coloration - however, this is not a permanent change and subsequent molts produce normal feather coloration).

There is also a good possibility of sickness, malnutrition (please refer to african grey nutrition), liver disease or kidney problems.

Although it is possibly that genetics is involved and that it is a mutation. It is easy enough to differentiate that -- depending on whether an African Grey developed these red feathers over time (which would be an indication of health problems), or whether they were born with it, which would point towards genetics / mutation.

Hyperkeratotic Swellings

Malignant Tumors

Tapeworms and Blood Parasites

Bad Feather / Beak Condition; Missing and Misshapen Feathers: Beak and Feather Disease (PBFD). A deadly, highly contagious (air-borne disease). Only supportive treatment available. No cure.

Toe Deformities (genetic)

Hematuria in association with lead poisoning

African Greys are Susceptible to: Psittacine Beak and Feather Disease, PBFD, Beak & Feather ... Aspergillosis: Many African species seem to have problems fighting off this fungal disease. Warm, moist environments frequently cause more infections ... PDD ... Sarcocystosis
