Long-billed corella

The long-billed corella, scientifically known as Cacatua tenuirostris, is a distinctive species of cockatoo native to Australia. It is primarily recognized by its predominantly white plumage, accented by a reddish-pink facial patch and forehead, and a strikingly long, pale beak. This specialized beak is a crucial tool for the bird, enabling it to excavate roots and seeds from the ground, forming a significant part of its diet.

Distribution and Habitat

This species is found in the wild across various regions of Australia, with its core range encompassing Victoria and southeastern New South Wales. Over recent decades, its territory has expanded, and it is now also observed in Tasmania, South Australia, and southeast Queensland. A notable feral population has established itself in Perth, Western Australia, raising conservation concerns due to potential hybridization with the endangered western corella. The long-billed corella thrives in open environments such as grassy woodlands, grasslands, agricultural fields, and urban parks, often found near red gum woodlands.

Behavior and Diet

Long-billed corellas are known for their social nature, typically forming monogamous pairs. Both members of the pair actively participate in nest-building, incubating the eggs, and raising their young. Their nests are commonly found in decayed debris, hollows of old eucalypts, or within the cavities of loose, gravely cliffs. The diet of the long-billed corella is varied, consisting of roots, seeds, corms, and bulbs, with a particular fondness for weeds like onion grass. While they consume native plants, introduced species now constitute a substantial portion of their food intake.

Vocalizations and Human Interaction

A remarkable characteristic of the long-billed corella is its exceptional ability to mimic human speech, often to near perfection. This talent has led to its popularity as a pet in many parts of Australia, where it is considered one of the best 'talkers' among native Psittacines. Conversely, the species is also viewed as an agricultural pest. Its habit of digging can cause significant damage to crops, and they are known to disturb asphalt, power lines, and sporting fields, leading to culling permits in certain areas. Tragic incidents, such as suspected mass poisonings, have also highlighted the complex relationship between this species and human activities and land use.
