I do seem to have difficulty with ducks! Yesterday afternoon I saw little at Montlake although I met others who had more luck. A hot September afternoon is probably a bad time to visit.
OK...one duck, considerably smaller than the Mallards and with a "blueish" beak.
It is Image 9368 in the recently recent bird sightings album.
