number 1: a group of them will spin on the water to concentrate the plankton that they love to mung. Its quite a weird thing to watch them line up in convoy then the lead quacker, actually they sort of whistle, will turn and the whole line will circle until they have surrounded what they want to surround. It's quite balletic.
number 2.you have to look carefully but you can just about see a little pink spot behind the eye, actually nowhere near where a ducks ear is. A more accurate name would be duck with pink spot behind eye. But that's a bit clumsy.
number 3 the bill has flaps either side which help in sifting the tiny thingys that these eat. They are also very rubbery and really weird to fondle.
So I hope that this is cute enough Sheila I will consult with my IT department for a solution to the main problem.
