Your Guide to Australia’s Spectacular Parrots.
Cockatoos are instantly recognizable parrots native to Australia, New Guinea, and nearby Indonesian islands. They are known for their iconic feather crests, boisterous noisy flocks, and brightly coloured plumage in shades of white, pink, red, and yellow. With 21 species, cockatoos come in a diverse range of shapes and sizes from the palm-sized cockatiel to the imposing red-tailed black cockatoo with wingspans over a meter wide. While each species has adapted to specialized regional habitats like rainforests or bushlands, they share key commonalities around breeding, behaviour, biology and care requirements. Read on to discover what makes Australian cockatoos such a one-of-a-kind parrot!
Core Traits and Attributes
The most instantly noticeable cockatoo feature is their vertical head crest, a fan of feathers they can raise dramatically to communicate strong emotions. Beneath this crown, cockatoos sport a large curved bill that acts like a powerful pair of pliers to crack tough seeds or extract hidden grubs. They put these sturdy bills to use, consuming a widely varied diet. Long broad wings provide maneuverability allowing cockatoos to be nimble through dense forests. And unlike many parrots, their long tails assist with balance while climbing. Bright whites, creams, pinks, and reds colour their bodies, often with distinct cheek patches or vibrant wing flashes.
Cockatoo Species and Variants
With over 20 species in multiple genera, cockatoos display fascinating diversity. The smallest cockatiel reaches just 30 cm long while the palm cockatoo and black cockatoos can grow larger than 60 cm with intimidating 1+ meter wingspans. Some other popular species include:

Did You Know? The iconic sulfur-crested cockatoo is known for raucous, noisy flocks. Galahs bond for life with their partners. Major Mitchell males put on an aerial dancing display during the breeding season while flashing their bright red wing patches.
Ecology and Regional Environments
While varied in size, most cockatoos favour forested habitats, from lowland and montane rainforests, to open eucalypt woodlands and coastal brushlands. They nest in tree hollows often located high off the ground. Tragically, loss of nesting grounds poses a major threat as deforestation and logging dramatically reduce older-growth trees. Cockatoos adapt feeding patterns to seasonal food availability, congregating in large migratory flocks towards late afternoon to communal roosting spots.
Breeding and Reproduction
The breeding season kicks off for most cockatoo species once rainfall rejuvenates vegetation and food sources. Bond breeding pairs engage in courtship feeding of potential mates to secure partnerships. Eggs are laid on a sparse leaf bed lining the hollow’s floor, with typical clutch sizes spanning 2-3 eggs for smaller species and just 1 for larger birds. Both males and females share brooding responsibilities, incubating eggs for around a month before hatching. Chicks fledge at 8-12 weeks, though some species take longer, not leaving the nest for 6 months!
Behaviour
Cockatoos are highly gregarious and social for much of the year, gathering in large noisy flocks, especially when foraging. This communal behaviour allows them to exhaust food sources efficiently while maintaining safety in numbers. Cockatoos also prefer to roost communally at dusk, as congregating giants like glossy black cockatoos wheel into roosting spots. Auditory communication is vital for maintaining group cohesion given densely forested environments. A wide vocabulary of squeals, squawks, and shrieks is used to signal location and express alarm.
Cockatoo Biology
Special tufting on cockatoo feet allows them to securely grip branches similar to parrots. But their leg scales have a unique pattern with more pointed scoops for enhanced climbing and clinging ability. They can apply over 35 kg per square cm of pressure with their vice-like bills – sufficient to crush macadamia nuts! Long lifespans mean captive cockatiels can live upwards of 25 years and larger cockatoos 60+ years. Bare yellow patches around the eyes are common signalling sexual maturity.
Housing Tips
Ensure cockatoos have sufficient indoor enclosure space with ample room to spread their wings. The largest black cockatoos require a minimum of 2 cubic meters. Galahs, corellas and other mid-sized species can thrive in 1 cubic meter. Small cockatiel cages should be 0.27 cubic meters at minimum. Provide abundant appropriate perch diameters and materials like natural branches. Enrich environments daily with puzzle feeders, shredding toys and opportunities to forage or bathe to support well-being.
Feeding Your Cockatoo
In captivity, cockatoos require balanced diets consisting of high-quality seed mixes and pellets, chopped vegetables, sprouted beans, and limited fruits in moderation as treats. Consult an avian vet to tailor nutritional needs by species. Key food groups like leafy greens, root veggies, peppers, and beans should comprise the majority of the diet supplemented by healthy protein sources. Limit toxic foods like avocados, alcohol, chocolate, and caffeine. Provide clean drinking water refreshed daily.
Finally, cockatoos represent a uniquely charismatic, acrobatic and exceptionally long-lived group of parrots found only in Australia and Australasia. Their stunning plumage and impressive size is matched by equally vivacious and noisy behaviours. Now the key to cockatoo happiness lies in providing sufficiently enriched environments supporting their high activity levels, foraging needs, and critically endangered status for some giant black cockatoo species especially. We encourage you to further research adopting a cockatoo to properly care for these magnificent birds and support conservation efforts protecting diminishing forest habitats.
