The Marbled Duck, or Marbled Teal, is a medium-sized duck adorned with a pale sandy-brown plumage, intricately mottled with off-white markings. Its scientific name, Marmaronetta angustirostris, reflects its marbled appearance and narrow bill. The species is characterized by a distinctive dark eye-patch and a somewhat shaggy head. Adults span approximately 39–42 cm in length, with females typically being slightly smaller than males. Juveniles resemble adults but exhibit more pronounced off-white blotching.
When identifying the Marbled Duck, look for its unique pale coloration and marbled pattern. The lack of a speculum on the secondaries and the pale wings without a marked pattern are key features to note in flight. The dark eye-patch and shaggy head are also distinctive characteristics that aid in identification.
