Similar Species

The shape of the bill is probably the best distinguishing feature between this and the other white Corellas of Australia. Can be confused with Little Corella and Western Corella where introduced in South West Australia.

Compared with Little Corella, Long-billed has:

  • extensive red-orange on chest (missing from Little)
  • bill longer (beware wear)
  • crest shorter
  • more extensive and more saturated red on lores
  • very slightly smaller (than Little)

Compared with Western Corella, Long-billed has:

  • extensive red-orange on chest (missing from Western)
  • much smaller size (around 8 cm)
  • generally more extensive and more saturated red on lores (but may be similar)
  • bill similarly long


Endemic to Australia with most common in Victoria and nearest areas of neighboring states. Feral populations elsewhere in Australia.


This is a monotypic species [1].

Some authors recognize both tenuirostris and mcallani as subspecies


Grassy woodlands and grasslands



They dig up the corms, bulbs and roots of plants (some of which are now rare). Insects are also eaten.


Nests are made about 25 feet up in the hollows of large old eucalypts, by both adults, who also share incubation of the eggs and care for the young. There may be several nests in one tree.
