The Story

The Cockatiel is the second most popular pet bird in the world and the ideal bird for first-time bird owners — combining manageable size with a gentle, affectionate temperament, a talent for whistling, and a long lifespan. Technically the smallest cockatoo (evidenced by the erectile crest), the cockatiel's crest position communicates mood precisely: flattened back = alarm; straight up = excitement; relaxed halfway = content.

Temperament & Personality

Gentle, affectionate, and social. A tame cockatiel will follow its owner around, sit on their shoulder for hours, and seek petting. Males develop extensive whistled repertoires and can learn entire tunes. Generally patient with gentle children.

Teeth Care

•Minimum cage 60 × 60 × 90 cm. Several hours out-of-cage daily. Pellet-based diet supplemented with fresh vegetables. Cockatiels are highly social — pairs or regular owner interaction prevents depression. Their fine white powder-down can be a respiratory irritant.

Vaccination Schedule

AdultboosterN/A

SpeciesnotesAnnual avian wellness examination by an avian-certified veterinarian is strongly recommended. Polyomavirus and Psittacosis (Chlamydia psittaci) vaccines exist for some species but are not universally recommended — discuss with your avian vet. Annual faecal parasite screening, crop cytology, and blood panel are standard avian preventive care.

PuppykittenscheduleN/A — birds do not follow standard vaccine schedules.

Health Overview

Chronic egg laying in females. Psittacosis. Respiratory infections. Night frights (sudden nocturnal panic causing cage bar injuries) — a night light helps. Proventricular Dilatation Disease (PDD) occurs. Significant powder-down production.

Common Conditions

•Name: Chronic Egg Laying • Severity: HIGH • Prevalence: COMMON • Description: Female cockatiels laying clutches repetitively — causes calcium depletion and reproductive disease. Remove nest boxes, cover cage 12 hours/day, hormonal treatment if persistent.

•Name: Feather Destructive Behaviour • Severity: MEDIUM • Prevalence: OCCASIONAL • Description: Feather plucking — usually psychological (boredom, loneliness) but medical causes must be excluded first.

•Name: Respiratory Infection • Severity: HIGH • Prevalence: OCCASIONAL • Description: Bacterial, fungal, or viral infections. Birds hide illness until severely unwell — any respiratory signs require urgent avian vet attention.

•Name: Proventricular Dilatation Disease (PDD) • Severity: HIGH • Prevalence: RARE • Description: Avian bornavirus causing neurological and GI damage. Signs include regurgitation of undigested seeds.

Fun Facts

The cockatiel's crest has approximately 6–8 distinct positions conveying different emotional states — experienced owners become fluent in crest-reading.

Cockatiels are one of the few birds that reliably learn to whistle complete tunes — champions in aviculture competitions can produce complex melodies of 10+ bars.

Wild cockatiels form flocks that fly rapidly between isolated water sources in Australia's arid interior, covering hundreds of kilometres in a day.
