There are two races of Western Corella.  The southern race can usually be
found along the Muir Highway between Rocky Gully and Lake Muir (in the
Manjimup region).  If you miss along Muir Highway, then try along
Hannekamp Road which is a dirt road on the eastern side of Lake Muir, or
try the roads north of Lake Muir.

The northern race is more often than not mixed with Little Corellas.
There is a mixed flock between Toodyay and Northam (usually near the
bridge about half way).  There is a very large (1,000+) flock often
between Bindoon and New Norcia NE of Perth.  There are a scattering of
corellas north of Perth around the Moore River.  I have seen them as far
north as Dongara.

The introduced Long-billed Corella seems to be expanding quite quickly.  I
have seen them in the semi rural area near the ALCOA Wellard Wetlands
south of Perth, and I saw one pair investigating a nesting hollow at
Bungendore State Forest in the Darling Range SE of Perth.  So they appear
to have the potential to spread wider than the metropolitan area.  I think
this is a major reason for the study by Allan Burbidge and John Blyth,
although with the numbers that already exist it might be getting a bit too
late to control as is the case with Rainbow Lorikeets.
