  • eye ring grey/blue, bare. More extensive beneath the eye.
  • eye dark brown.
  • underparts, under wing and undertail are washed pale yellow
  • bill slender and horn-coloured with a long upper mandible: hooked
  • legs and feet grey

Sexes similar.

Similar species

Similar to Little Corella and Long-billed Corella where those species occur in South West Australia (especially Perth area).

Compared with Little, Western has (differences in descending order):

  • bill longer than little. Long-billed individuals of Little may approach the length of Western if Western's bill is worn
  • larger size (around 7 cm)
  • bases of the throat feathers more extensively red in Western (may be difficult to see)
  • crest is slightly longer than little, but the difference is not great
  • loral orange/pink is similar in both species but perhaps slightly more saturated and extensive in Western

See Long-billed Corella for comparison with that species.


Australian endemic only found in Western Australia.

There are two subspecies

  • C. p. derbyi: Western Australia (Dongara to Moora and Quairading). [Smaller than pastinator]
  • C. p. pastinator: South-western Western Australia (Lake Muir and Unicup region). [Larger than derbyi]


Near water courses, grassy woodlands and where seeding grasses are found.



They feed mainly on the ground; the diet includes cereal grains, grasses and exotic weeds, bulbs and germinating cereals, insects and their larvae.


The nest is in a hole in tree, mainly in native Eucalyptus, lined with woodchips. 2 - 3 eggs are laid and are incubated for 22 to 26 days, by both parents. The young are cared for by both parents, and fledge at about 8 weeks.
