Musk duck

Biziura is a genus of stiff-tailed ducks endemic to Australasia and containing one living and one fossil species.

Etymology
No expl. (Stephens 1824, Gen. Zool., XII (2), 221); ex “Biziura” of Leach MS. Probably from Greek βιζηαι bizēai straws (originally the name for a straw mattress or matting) and ουρα oura tail, with reference to the stiff, spiky tail-feathers of the Musk Duck (cf. Greek βυζην buzēn thick, matted; ουρα oura tail, in allusion to the pincushion-like undertail coverts exposed in display by the drake).
