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.
