This male Hardhead (on the right of the picture) looks like he has something to say. To his left, a Pacific Black Duck seems mildly surprised, or perhaps just living up to his scientific name, Anas superciliosa.

And perhaps the Hardhead thinks that his mate is paying too much attention to his supercilious rival!

This is the first time I’ve photographed a Hardhead. Evidently they’re the only Australian duck that can claim the name of true diving ducks, as they dive deep into the water to feed. The males have white eyes while the females have brown eyes.
