I've observed Blue-billed Ducks over several years at Fyshwick Sewerage Ponds in Canberra and this behaviour is quite common/ frequent. I don't have notes that tell me at what time/s of year the behaviour occurs but it always seems to involve two males and a female. I've always assumed it is courtship, largely aimed at impressing the female, but perhaps also at intimidating the other male suitor.

I saw an intersting behaviour by a male Blue Billed Duck today. He bobbed up and down in the water several times and grabbed a couple of bill-fulls of water and splashed them out. I'm not sure whether he was aiming the display at the nearby female or a slightly more distant male. The two males chased each other back and forth during the next five minutes, but I'm not convinced that the earlier display was aimed at the male. It seemed to be aimed at the female.

Has anyone seen similar behaviour in Blue Billed or other ducks?
