Long Billed Corella

The Long Billed Corella is a cockatoo and many people tend to confuse this bird with sulphur crested cockatoos. The Long Billed Corella seems to have increased considerably in numbers over recent years and is considered a pest in many areas.

Over the summer, along the Loddon River in Bridgewater, these birds congregate in the river gums of an evening and strip them bare.  I’ve never seen them eating leaves, just destroying the vegetation.  They have also been known to tear up pieces of asphalt road and damaging power lines.

Well that’s the bad bits, but they are also kept as pets. They are regarded as the best talker of the cockatoos and mimic words and sentences extremely well.

Distribution and Habitat

The long-billed corella can be found in the wild in Victoria and southeastern New South Wales. It has extended its range in the past 20 years and can now be found in Tasmania, Adelaide and southeast Queensland. A feral population resides in Perth which has implications, as this species may hybridize with the endangered western corella.

The long-billed corella is found in grassy woodlands and grasslands, including pasture, fields of agricultural crop, and urban parks.


Breeding generally takes place from July to November. Long-billed corellas form monogamous pairs and both sexes share the task of building the nest, incubating the eggs, and caring for the young. Nests are made in decayed debris, the hollows of large old eucalypts, and occasionally in the cavities of loose gravely cliffs. 2–3 dull white, oval eggs are laid on a lining of decayed wood. The incubation period is around 24 days and chicks spend about 56 days in the nest.


The long-billed corella typically digs for roots, seeds, corms, and bulbs, especially from the weed onion grass. Native plants eaten include murnong Microseris lanceolata, but a substantial portion of the bird’s diet now includes introduced plants. They also eat sunflower seeds.

Long Billed Corellas As Pests

Long-billed corellas are viewed as agricultural pests, particularly in western Victoria and Western Australia. They can create significant crop damage and are also well known for tearing up pieces of asphalt along roadsides and even damaging power lines. Permits are regularly issued in Western Australia and sometimes issued in Victoria for the culling of this species. Within NSW, the corellas are the most common pest among sporting fields and golf courses, as they can dig holes in the ground up to 3 in across and 6 in deep.
