The green Rosella (or Tasmanian Rosella) was once much more common (particularly around orchids) but the population has declined over the years. One suggestion as to the cause is competition for nesting sites with the introduced Starling.
I do see small flocks from time to time but generally I see them in pairs. One pair visits our backyard where they feed in the Eucalypts and Native Cherries.
I'd love to know the origin of this birds name. Caledon is the old Roman name for Scotland and the suffix icus changes it to an adjective - thus caledonicus would mean Scottish. It seems a strange name for a Tasmanian endemic. However, there are other Australian species with the same name. For example the Nankeen Night Heron is Nycticorax caledonicus, so perhaps there is another explanation. Can anyone shed some light on this?
Below are are a couple of photos I took yesterday. In the first shot the sky is completely blown out but I actually quite like the effect.

Green Rosella - Platycercus caledonicus
Update: Thanks to Snail in the comments below for the explanation for the name caledonicus.
From Wikipedia:Now I just need to find out how Gmelin acquired his Tasmanian Rosella in 1788.
The Green Rosella was described by the German naturalist Johann Friedrich Gmelin in 1788. The species specific epithet was derived from the mistaken belief the bird was collected from New Caledonia.
