History & Origins
The grey cockatiel is the natural form found across the Australian outback, first kept in Europe from the 19th century. Every captive colour mutation descends from this wild type. Mature males develop a brighter yellow face and lose the barred underside of the tail, helping tell the sexes apart.

Normal Grey Common Health Issues
Conditions seen more often in this breed, and how owners and vets help manage them. This is general guidance, not veterinary advice — always speak to your vet.
Vitamin A deficiency
Seed-heavy diets lack vitamin A, leading to respiratory infections, poor feather quality and mouth lesions.
Care: Offer orange and dark-green vegetables and a vet-approved pellet diet; an avian vet can advise on supplementation.
Fatty liver disease
All-seed diets high in fat lead to hepatic lipidosis, causing an overgrown beak, poor feathering and lethargy.
Care: Switch gradually to a formulated pellet base with vegetables under avian-vet guidance and limit fatty seeds.
Night frights
Cockatiels are prone to thrashing panic in the dark, injuring wings and breaking flight feathers against cage bars.
Care: Use a dim night light, keep the cage away from sudden noises, and provide a calm, predictable sleeping spot.
