Blue-billed duck

blue billed duck

Blue billed duck, Oxyura australis, IMG 3329 - Only someone with the intellect of a pickled cucumber could fail to guess the most prominent physical feature of the blue-billed duck, for the name says it all, but it's only the male of the species who has this conspicuous feature. His grey blue bill, which becomes bright blue during the breeding season, ensures that he stands out among any crowd of waterbirds, but his mate, like the female shown above, retains only grey colouring on her bill.
