Hard to say how common inter-breeding is. It is not common, considering
how common both species are, which is why it is rare. If one species was
common and the other species was rare, then inter-breeding would
probably happen more (because the rare species has little option about
finding a correct mate). Probably every 2 or 3 years someone finds at
least one of these hybrids in the COG area. That does not mean it is a
new bird each time. They might survive many years but I have no idea
either way if that is what is happening.

Either this bird gets around quickly or there's more than one!
Yesterday
(Saturday) afternoon in Watson, near the primary school, a hybrid on its
own. Front and head as Crimson Rosella, wings and tail Eastern.
Can you knowledgeable folks tell me how common inter-breeding is?
