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?

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.
