He looks a similar colour to a peacock, but without the long tail feathers.
Your bird is definitely a pheasant.
Also some one told me that if you see a peacock with its feathers in full display, it is because he is upset and displaying his superiority, therefore it is not a good idea to get too close to him, is that correct?
I've checked with the Duck Man. He tells me that peacocks aren't particularly aggressive, and that their displaying is pure sex, no aggression.
I also learned that they are sex mad, and will attempt to rape any brown bird of about the right size.
One of my colleagues used to keep a buzzard. There was a feral peacock roaming around his village at the time, and he told me how one afternoon he set the buzzard up on her bow perch on the lawn in the sunshine. He heard squawking and flapping and came out to find the buzzard being sexually harassed by the determined peacock. The buzzard took several hours to calm down, apparently. The peacock survived, but was later reported attempting to rape chickens in other parts of the village. There were even rumours about ducks.
Oh, and the Duck Man's white peacock has gone wandering off (looking for birds to seduce, no doubt). So if anyone around York-ish sees a white peacock in a place where you don't usually see one (and that's most places, really), please let me know.
