Anas scutulata

S. Müller

, 1842,



Previously placed in Cairina. Birds of Sumatra and Java, with much more white in plumage, sometimes split as race leucoptera, but extensive albinism in Sunda population normally attributed to hybridization or inbreeding; however, structural and postural differences between Sunda and continental birds do suggest racial differentation; further morphological and molecular studies needed. Currently treated as monotypic.


Relict populations in India, Bangladesh, Myanmar, Thailand, Laos, Vietnam, Cambodia and Sumatra; formerly more widespread throughout range, probably extinct in Malaysia and on Java. Recently recorded in Bhutan#R.
