Hi Simon

FYI, some previous discussion re Little x Long-billed Corellas in Canberra:

There was a pair of corellas (one Little, one Long-billed) at/in a hollow in a 
Blakely's Red Gum on 22 September last year at one of the sites that I survey 
regularly on Red Hill as part of COG's Woodland Survey. 
Prior to this, a Long-billed Corella had been recorded during these Red Hill 
surveys on:

17 Dec 2006
29 Mar 2008     with a flock of Sulphur-crested Cockatoos
27 Jun 2009     appeared to be a paired with a Little Corella as evidenced by 
4 Oct 2009     ousted a galah from the vicinity of a nest hole then occupied 
the entrance for the 10-minute duration of the survey.
13 Dec 2009

The Red Hill site is not that far from Callum Brae - may well be the same pair.

For some years now I have encountered, on and off, a corella pair, one 
long-billed and one little corella.  I always know them because long-bill has a 
metal ring on one leg.  There have been no reports of them breeding, but, if 
the little corella is the same one, the pair have been faithful for years.  One 
might call them Romeo and Juliet, albeit with greater longevity.

Today they turned up at nursery corner, and a third corella was with them, and 
obviously very close because at one stage little was grooming the third 
arrival.  Now, the new arrival looks a bit like a long-billed, but not quite, 
with less red wash about the face and neck.  Also, its crest is more like that 
of a little.

Attached is a photo (very small to comply with chatline rules) of the three.  I 
have other more detailed images, and if you let me know you are interested, I 
can send them to you privately.  They are really not of a high enough standard 
for me to want to put them on FlickR for everyone on the planet to see.

Hi all,

According to E.M. McCarthy?s Handbook of Avian Hybrids (2006, OUP), the
following combinations with Little Corella occur (except for x sulphurea
apparently all in the wild):
Cacatua sanguinea [Little Corella]
x galerita [Sulphur-crested C.]
x leadbeateri [Major Mitchell?s C.]
x pastinator [Western C.]
x roseicapillus [Galah]
x sulphurea [Lesser Sulphur-crested C.]
x tenuirostris [Long-billed C.]
x Callocephalon fimbriatum [Gang-gang C.]
