Hardhead
Sign in to saveAlso known as Aythya australis, Australian white-eyed duck
The hardhead (Aythya australis), also known as the white-eyed duck, is the only true diving duck found in Australia. The common name "hardhead" has nothing to do with the density of the bird's skull, instead referring to the difficulty encountered by early taxidermists in processing the head. Hardheads are found in wetter, coastal regions of Australia, particularly in the south-east, but are known to disperse as far afield as New Guinea, New Zealand, and the Pacific Islands.

Weibchen der Moorente mit braunen Augen Männchen mit deutlich erkennbaren hellen Augen und auffälliger Schnabelbinde Die Australische Moorente (Aythya australis) ist die einzige Tauchente Australiens. Sie kommt auf dem gesamten australischen Kontinent vor. Auf Tasmanien ist sie jedoch nur selten zu beobachten. In ihrer Gefiederfärbung erinnert sie an die europäische Moorente. Sie ist allerdings etwas größer und das Gefieder ist weniger einheitlich braun. Die IUCN stuft die Australische Moorente als nicht gefährdet (least concern) ein. Der Bestand wird auf 100.000 bis 1 Million geschlechtsreifer Individuen geschätzt. In Australien zählt diese Art zum Federwild.
