Common Merganser

Male Common Merganser is 58–72 cm long with a 78–97 cm wingspan, and a weight of 0.9–2.1 kg; males average slightly larger than females but with some overlap. It has a crest of longer head feathers, but these usually lie smoothly rounded behind the head, not normally forming an erect crest. Adult males in breeding plumage are easily distinguished, the body white with a variable salmon-pink tinge, the head black with an iridescent green gloss, the rump and tail grey, and the wings largely white on the inner half, black on the outer half. The bill and legs are red to brownish-red, brightest on adult males, dullest on juveniles.
