Barney,
Crosses of Crimosn and Yellow Rosella are a regular occurrence in the
Albury-Wodonga region. I saw a mixed pair many years ago near teh Bandiana Army
Camp. The first house we lived in (near Nailcan Hill) often had mixed pairs
with an odd mix of young birds - some looked like Yellows, some Crimsons and
yes many looked like Adelaides). I only get Yellows in the house we are now in
(which is only about 200 metres away but closer to town and further from eth
bush). I only see Yellows in the street trees in the CBD. At Beechworth only
Crimsons are found.
Not certain how much further upstream the Yellows extend, but once you get
into the serious mountains then only Crimsons occur.
I vaguely recall seeing a mixed pair at Gundagai on the Murrumbidgee as well,
so probably where the foothills meet the river this occurs reasonably regularly.
The more interesting thing is the "Crimson" Rosella on Kangaroo Island in SA,
whereas the mainland are all Adelaide types.
My parents near Murwillumbah on the north coast of NSW have for many years had
a hybrid male Eastern/Pale-headed breeding with a female Eastern. Don't see
many pure Pale-heads in the Tweed Valley, but they are more common on the Gold
Coast.
Dad also reckoned he had wild Long-billed and Little Corellas near Brunswick
Heads where both species would be locally introduced.
Cheers,
Peter
