The male has a dark blue cere (skin at the base of the bill around the nostrils). The female has light blue cere that turns brown when breeding. Young Budgerigars are similar to adults, but are duller and have a dark brown eye.

Feeds mainly on ground on seeds of native plants and grasses.
Nests in a hollow of tree. Lays 6-8 rounded white eggs.
throughout much of the interior of mainland Australia - not found in far south-west, the north of the Northern Territory, Tasmania and most of the east coast.
