Hi Terry,
It is Wigeon not Widgeon, A common mistake.
Since I go all the time to the garden, I think you need to get at eye level with the ducks, very easy to do there, just lay down………
The duck is also out of focus.
I have the 70-200, it is not very good with the 2x, I would use a 1.4 or 1.7 or just use it at 200 at this site.
It is so easy to get really close to them, I would try that.
The water looks cool, it has a nice swirl and color to it.
