Hi Folks,
I have recently been in the land of WA around South Perth.
I am curious as to the location status of Corella’s over there as I have found researching on the net somewhat confusing.
I am to assume from Eremaea and Media reports that the Eastern Long-billed Corella is now resident there and becoming a pest? True?
What about Western and Little.
Do they co-habit? I am assuming a large flock around Armadale to be Western?
Cheers and thanks in advance.

G’day Steve,
I think it would be highly unlikely that your Amadale flock was Western. Western Corella is very uncommon in the greater Perth area, and records usually involve one or two individuals. The northern population occurs in the wheatbelt north-east of Perth, including around towns like Moora, Wongan Hills, and New Norcia, and can approach the outskirts of Perth around Bullsbrook (not sure how regularly, but I’ve seen them there a couple of times). The southern population is restricted to the Rocky Gully/Lake Muir area in the deeper SW.
Little Corella and Eastern Long-billed Corella are both resident and well established around Perth. Overall Little is probably commoner, but the relative abundances of the two species vary locally across Perth. Both are considered pests as they compete for nesting hollows with native parrots and cockatoos (plus noise and damage to grassed areas).
Mixed flocks are reasonably regular and Little & ELB occur together in many areas of Perth. In the wheatbelt north-east of Perth, mixed Little/Western Corella flocks also occur.
Hope this is what you were after Cheers, John
PS – Eremaea is not widely used in WA, so I would excercise some caution using it for WA as it gives misleading distributions for a couple of species
