Примечания
This chestnut brown duck is confusable only with the fulvous whistling duck (D. bicolor) but has chestnut upper-tail coverts.....unlike the creamy white in the latter. When flying straight, their head is held below the level of the body as in other Dendrocygna species. The crown appears dark and the sexes are alike in plumage. They fly slowly but with rapid wing-flapping and usually produce a repetitive wheezy seasick call as they circle overhead. They are very nocturnal and often rest during the day. The outermost primary feather has the inner vane modified. This has been said to aid in producing a whistling sound in flight, although this has not been supported by field studies. Elevation: 0 m. Date added to IBC: June 22, 2016.
