Sorts of duck

Mallard, and Northern Pintail being chased by Wigeon, all in Hachimangu pond, Kamakura. I noticed that one of the Northern Pintails at Hachimangu is more elegant than the others, with a striking glint of green to his head, so I was interested to see on the internets that Mallards and Northern Pintails can inter-breed! Meanwhile, at home, we are still enjoying duck-fried potatoes, Ducky having been eaten at Christmas last year.
