Battle Royal

The cock blue tit saw another cock in his territory but unfortunately for him it was his mirror image.  He spent much time fighting it and let me within 5 feet of him without fear.  His bride arrived and had her own battle with her image too.  They were amazing in their fierceness and agility - see extras. Eventually I had to cover the mirror with a cloth for they were wasting so much energy.  Tomorrow will paint the mirror white
