  • Intestinal and proventricular worms
  • Fatty Liver Syndrome


Grey-cheeked Parakeets

Hawk-headed Parrots

Jardine’s Parrots:

  • Respiratory Signs, Chronic Depression, Weightloss: Aspergillosis

Mynahs / Sturnidae

  • Listlessness, Regurgitation, Dyspnea, Weight Loss, Diarrhea, Coughing, Wheezing, Syncope: Iron Storage Disease and related entities – excessive accumulation of iron in the liver. Most of the affected birds with acute signs die.


Canker (Trichomoniasis, more commonly known as “pigeon canker)


Pionus Parrots are relatively healthy, though they are more susceptible to aspergillosis infections than other species. The main symptom is heavy, belabored breathing. The pionus is also susceptible to the following diseases:

  • Bacterial and fungal infections
  • Feather-picking
  • Mate aggression
  • Psittacosis (Parrot Fever)
  • Pox virus infection (Primary disease of imported birds)
  • Toe necrosis
  • Toxicity, ingestion of metals
  • Vitamin A deficiency / Poor eating habits – Vitamin A occurs in orange-colored produce, such as apricots, cantaloupes, carrots, red peppers, pumpkins and sweet potatoes. To resolve Vitamin A deficiency, try adding foods like sweet potatoes (either cooked or steamed until soft), mashed up with other fruits will be both loved by your pet bird, as much as it is good for her or him. Many birds also enjoy fresh carrot juice – or try offering shredded carrots. Natural sources are preferable over synthetically produced nutrients, which may not be absorbable and could easily be overdosed).
  • Wheezing / Snorting: When excited or frightened, birds of this genus may make a characteristic wheezing or snorting sound that is sometimes mistaken for a sign of distress.

Poicephalus / Brown-headed parrots

Generally healthy birds. However, the following diseases have been reported in this species:
