That raises another interesting question - the large flock yesterday
and most other times is solely Corellas, no Sulphur-crested
Cockatoos. So when, how and why do the corellas disperse and mix
with the cockatoos, and then perhaps re-congregate in their
mono-specific group(s)?
Would corellas roost with cockatoos?
If they regroup mono-specifically in the evening, how does the
re-grouping process work since they appear to have re-grouped before
reaching their roosting site?

They come over our house in Griffith most mornings shortly after sunrise
heading in the Narrabundah direction - I think that lot roosts overnight in
Telopea Park.
I was walking past Manuka Oval yesterday morning and there was a mixed flock
feeding on the ground - about 25% little corellas, 75% sulphur-crested
cockatoos, and three long-billed corellas in there as well.
