I have named them Donald and Mickey, because Mickey has large black feathers on the top of its head, like two large Mickey mouse ears.
Having very similar colours and one being slightly smaller than the other, I am guessing that it is a dad and son team. They rarely fight each other and like to wander around the garden. They often walk up to the patio door and stare at the glass, probably intrigued by the reflection.
Recently, another pheasant came into the garden. This caused some friction which ended up in a fight. It was quite intriguing watching them behave. It was like a little dance with their feathers slightly lifted to make themselves look a little bigger than they actually are.
Below is a small video showing you the fight. Don't worry. Nobody gets hurts! Well, not this time anyway.
