The Long-billed, or Slender-billed Corella is a lovely Cockatoo who lives both in the wild and in captivity throughout Australia.
Long-billed Corellas are generally found near
streams in grassy areas or open woody areas. They are highly social, gregarious birds and gather at feeding sites in flocks of hundreds of birds. Often, Long-billed Corellas will associate with the Sulphur-crested Cockatoo. While feeding, one bird will remain in a tree and keep watch while the others feed. They only feed during the cooler hours of the day, preferring to rest at midday in shade.
This Corella, when disturbed, will shriek loudly while taking wing. They feed mostly on roots and onion grass supplemented with all sorts of seeds, vegetation and fruits in addition to insects. From July to November,
they breed, making their nests in hollow treetops or branches. They have been observed making burrows in soft dirt banks when they cannot find a suitable tree. Both the male and female tend to the young and sit
their the eggs!
They have long upper mandibles
and the entire bird grows to about
38 centimeters in length. They have white plumage, which is yellowish under the tail and wings. There is a large blue-gray area about the eye, which lacks feathers. Long-billed Corellas are characterized by the red coloring they have about their necks and in the area of their nostrils.
They also have a red crescent on their breasts and red foreheads. Their white crests are rather small. Males generally have longer beaks than do females, and more red color in addition to being generally larger.
In cultivated areas,
this Corella can seriously harm grain or millet and rice fields, and are endangered in some areas because they are persecuted as agricultural pests. First recognized by Kuhl in 1820, Long-billed Corellas are native to southeastern Australia.
