Budgerigar Variety · Domestic colour variety (wild type native to inland Australia)
Sky Blue
A blue-series mutation that removes yellow, leaving a clear sky-blue body.
By the WARN Research & Conservation TeamChecked against IUCN Red List & CITES sourcesLast updated
In brief
The Sky Blue budgerigar is a 'blue series' mutation in which the yellow pigment is absent, turning the green body sky-blue and the mask white. It is one of the oldest and most popular budgie colours.

History & Origins
The budgerigar (Melopsittacus undulatus) is a small parrot from the arid interior of Australia, where huge nomadic flocks follow seasonal rains. First brought to Europe in the 1840s, it became one of the world's most popular cage birds. Selective breeding has since produced a wide spectrum of colour mutations and the larger 'English' exhibition type, all descended from the green-and-yellow wild bird.
Sky Blue Fun Facts
- Blue budgies lack the yellow pigment that makes wild birds green.
- Sky Blue was one of the first mutations established in aviculture.
- The blue gene is recessive, so two carriers are needed to produce it.
- Cobalt and mauve are darker versions of the same blue series.
Sky Blue 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.
Goitre (iodine deficiency)
An iodine-deficient, all-seed diet enlarges the thyroid, pressing on the airway and crop and causing laboured breathing, a clicking voice and regurgitation — classic in budgerigars.
Care: Feed a varied diet with a vet-approved pellet base rather than seed alone; an avian vet can treat affected birds with iodine and dietary correction.
Lipomas (fatty tumours)
Budgerigars, especially older or overweight birds, commonly develop benign fatty lumps (lipomas), most often on the chest or abdomen.
Care: Keep birds active on a balanced, lower-fat diet; an avian vet can assess lumps and, where needed, manage or surgically remove them.
Scaly face (mites)
Knemidokoptes mites burrow into the skin around the beak, cere, eyes and legs, producing crusty, honeycomb-like growths that can deform the beak if untreated.
Care: An avian vet confirms mites and treats with an appropriate antiparasitic; treat and clean the bird's cage and accessories at the same time.
