About Cacatua tenuirostris (Kuhl, 1820)
This species, known as the long-billed corella with the scientific name Cacatua tenuirostris (Kuhl, 1820), has the following physical description. Adult long-billed corellas measure 38 to 41 centimeters in length, have a wingspan of approximately 80 to 90 centimeters, and average 567 grams in weight. They have a long, bone-colored beak and a ring of featherless bluish skin surrounding the eyes. Their plumage is mostly white, with reddish feathers located around the eyes and lores. The undersides of the wing and tail feathers have a faint yellow tinge. Regarding distribution and habitat, wild long-billed corellas are originally found in Victoria and southeastern New South Wales. Since the 1970s, the species has extended its range to include Melbourne, Victoria, and can now also be found in Tasmania, South Australia, and southeast Queensland. A feral population has been established in Perth, Western Australia since the mid-1980s. This feral population carries conservation implications, because the long-billed corella may hybridize with the endangered western corella. Long-billed corellas inhabit grassy woodlands and grasslands, including pastures, agricultural crop fields, and urban parks. They can also be found in red gum woodland.
