The Brazilian merganser (Mergus octosetaceus) is a South American diving duck in the Mergus genus. It is one of the most threatened waterfowl species in the world, with possibly fewer than 250 birds in the wild and a small number kept in captivity in Brazil. [1] It has a long, sharp-edged beak with a great number of tooth-like edges.
They are sympatric with Mandarin ducks (Aix galericulata); perhaps competing for nesting holes (which neither can excavate themselves). In its winter quarters, the scaly-sided merganser might compete with other Merginae with which it shares its habitat then, e.g. common mergansers (M. merganser) and common goldeneyes (Bucephala clangula).
