In cultivated areas, Long-billed Corellas 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. Of the two subspecies of Long-billed Corella, Western Long-billed Corellas inhabit the eastern parts of the range. They have been crossed with Major Mitchell's, Sulphur-crested, and Galah Cockatoos.
