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?
