Cacatua tenuirostris

CACATUIDAE

Long-billed Corella

Description
The Long-billed Corella is a medium-sized white cockatoo with a short crest (not always visible) and short tail, stocky body and a distinctive long upper mandible to its bill. There is a faint yellowish wash on the undersides of its wings and tail, and orange-red splashes on its forehead, throat and an orange-red crescent across its upper breast. The eye ring is pale grey-blue. It is a conspicuous and gregarious species, often seen foraging in large flocks on the ground.
Feeding
Grass seeds are the preferred diet of Long-billed Corellas, particularly those from grain crops. They also eat corms, bulbs and roots, especially from the weed onion grass, Romulea. Insects are also eaten. Native food plants include Murnong, Microseris lanceolata, but about 90 % of the diet now includes introduced food plants.
Breeding
Long-billed Corellas form monogamous pairs and both parents prepare the nest, incubate the eggs and feed the young. Nests are made in the hollows of large old eucalypts, and sometimes in cavities of loose gravelly cliffs (scoria). The eggs are laid on a lining of decayed wood.
Call
A loud, quavering, two-syllable 'wulluk-wulluk' or 'cadillac-cadillac', as well as a harsh screech.
