THE MOULTS AND PLUMAGES OF THE MANED DUCK Chenonetta jubata ON THE SOUTHERN TABLELANDS OF N.S.W.


The moults and plumages of a wild population of  Maned Docks Chenonetta jubata were studied. Descriptions of duckling plumage development are presented so that they may be used to identify duckling age in the field. Characteristics of a distinct juvenal plumage are also described. The distribution of body moult shows a peak in moult activity at the beginning of the year and this, combined with the existence of a male "eclipse" plumage late in the year, suggests that there may be two body moults per year.
