This is a photo (albeit a very bad one) of a Ring-necked (or common) pheasant (Phasianus colchicus). We think.
They were introduced into Australia in 1864 as a game bird. Efforts to establish it have been largely unsuccessful and it is restricted to Tasmania, King Island (in Bass Strait) and Rottnest Island (WA). It's natural range is Russia but it is naturalised in Europe.
The interesting thing about this is that the photo was taken at my sister's house in Faulconbridge in the Blue Mountains, NSW. My sister first saw it just before Christmas and I saw it again yesterday (assuming it is the same individual).
What is it doing there?
