I'm back and I'm mean!!

Regular readers may know that I have been blipping pictures of a beautiful, solitary, female Mandarin duck which has been around all through the winter.
Well!! This morning as we took our regular stroll around the park and the river, we very quickly became aware of the presence of a male Mandarin who was clearly up for some action - of any sort, so it would seem.
It displayed continuously to the female with a series of highly stylized moves, accompanied by some bizarre calls! Interspersed with this were efforts to take on any and all of the male Mallards who were anywhere nearby.
It has to be said that the female did not look too impressed by any of this macho posturing, as if to say "You s*d off for six months, and now you come waltzing back expecting me to be at your quack and call!! 
You can do one matey!!"
