As the "perching ducks" were split up, the comb duck was moved to the Tadorninae or shelduck subfamily. [ 3 ] Analysis of mtDNA sequences of the cytochrome b and NADH dehydrogenase subunit 2 genes , however, suggests that it is a quite basal member of the Anatidae, vindicating the earliest placement, but its closest living relatives cannot be ...
The American black duck (Anas rubripes) is a large dabbling duck in the family Anatidae. It was described by William Brewster in 1902. It is the heaviest species in the genus Anas , weighing 720–1,640 g (1.59–3.62 lb) on average and measuring 54–59 cm (21–23 in) in length with an 88–95 cm (35–37 in) wingspan .
