Looks like a male eastern rosella hybrid (blue cheeks) on right. And young one looks indistinguishable from 1st immature Crimson (100%) Rosella.

And this:   female hybrid on right is at least 3 years old, on left is the last season's offspring with male crimson partner. She is dominant at feeders otherwise all rosellas solely of crimsons  - the nearest easterns are 200 m away in rural paddocks/grasslands, and do not enter our dry sclerophyl around feeder.
Any views on % parentage of the female hybrid ?  75:25 is our guess. She is very symmetrical ! (and pretty) .

This one ...

... and its conventional partner have been regulars in my backyard for the past 3-4 years. However, the consensus seems to be that its exhibiting a form of leucism rather than being a Crimson/Eastern hybrid. When first noticed in March 2018, it appeared to be feeding what I assume to be its mate (or vice versa) ...

I have not noticed it feeding any young in the years it has been around - so don't know if its part of a breeding pair.

Yes, Crimson/Eastern Rosella hybrids are seen around here every so
often. Here's a photo I took about ten years ago near the Yarralumla
Nursery, of a Crimson/Eastern Rosella hybrid with a Crimson Rosella.

Does anyone know if the hybrids can reproduce, or are they the avian
equivalent of mules?

Last week I was watching a Crimson Rosella and an immature Eastern
Rosella as they flew down to my frog pond in Giralang for a drink. As
they were sitting there, I saw the Crimson Rosella regurgitate some
food and feed the Eastern Rosella.
Is this a common observation? I'm aware of the cross
breeding between Eastern and Pale-headed further north but not between
these two. Maybe just sharing a meal with a friend?

Cheers - Woo
