Sporting bright red tail feathers, the Red-tailed Black Cockatoo is a stunning sight throughout most of mainland Australia, though their numbers are fewer in the south.

Cockatoos nest in deep hollows that form in very large, old eucalypts, some more than 200 years old. Due to this, the cockatoo is at risk as many old trees have been removed, and limited nesting sites remain. Red-tails can nest year round, and usually only produce one egg. It takes chicks around 3 months to fledge, meaning there is a high demand on parents to supply food during this time. In an effort to increase breeding sites for Red-tails, some national parks have installed artificial nesting hollows.

The National Zoo & Aquarium is home to 2 Red-tailed Black Cockatoos: Bana and Kanbi.
