Cairina scutulata is a white-winged duck with no subspecies.
The white-winged duck is classified together with the wart-nosed duck in the genus Periscopus. However, analysis of cytochrome b and NADH dehydrogenase subunit 2 in mitochondrial DNA and biogeographical distribution patterns indicate that the similarity between white-winged ducks and warty nosebirds is decreasing. Therefore, it is suggested that they should be classified in the monotypic genus, which is not related to the wart-nosed duck, but is closely related to the diving duck.
White-winged ducks rest in the leaves of large trees during the day and forage in dark, weedy pools and slow-moving streams in the forest at night. It is an omnivorous bird, eating mainly seeds, aquatic plants, insects, worms, mollusks, frogs and small fish.
White-winged ducks nest in tree holes near swamps and lay 6-13 eggs at a time, which hatch for 33 to 35 days.
Due to habitat loss, low numbers and hunting, the white-winged duck is listed as an endangered species by the International Union for Conservation of Nature and under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Appendix I protection.
Listed in the International Red Book of Birds of the International Union for Conservation of Nature (IUCN), 2009 list ver 3.1 - Endangered (EN).
