The long-billed corella, also known as long-billed cockatoo or slender-billed corella[2] (Cacatua tenuirostris), is a cockatoo native to Australia, which is similar in appearance to the little corella.[3] This species is mostly white, with a reddish-pink face and forehead, and has a long, pale beak, which is used to dig for roots and seeds. It has reddish-pink feathers on the breast and belly.
Taxonomy

Description
The adult long-billed corella measures from 38 to 41 cm in length,[5] has a wingspan around 80–90 cm, and averages 567 g in weight.[5] It has a long, bone-coloured beak, and a rim of featherless, bluish skin around the eyes. The plumage is predominantly white with reddish feathers around the eyes and lores. The underside of the wings and tail feathers are tinged with yellow.
Distribution and habitat
The long-billed corella can be found in the wild in
The long-billed corella is found in grassy woodlands and grasslands, including pasture, fields of agricultural crop, and urban parks.[5]
Ecology and behaviour
Call
The call of the long-billed corella is a quick, quavering, falsetto currup!,[3] wulluk-wulluk, or cadillac-cadillac combined with harsh screeches.[5]
Breeding
Breeding generally takes place in Austral winter to spring (from July to November).
Feeding
The long-billed corella typically digs for roots, seeds, corms, and bulbs, especially from the weed onion grass.[3] Native plants eaten include murnong Microseris lanceolata, but a substantial portion of the bird's diet now includes introduced plants.[5]
Relationship with humans
As pets
Long-billed corellas are now popular as pets in many parts of Australia,
As pests
Long-billed corellas are viewed as agricultural pests, particularly in western Victoria and Western Australia. They can cause significant crop damage, are known for tearing and playing with pieces of asphalt along roadsides, and even damaging power lines. Permits are regularly issued in Western Australia (and sometimes in Victoria) for the culling of this species. Within New South Wales, the corellas are the most common avian pest among sporting fields and golf courses, as they can dig holes in the ground up to 3 in across and 6 in deep.[5]
