Mandarin Duck
Aix galericulata
The mandarin duck is among the smaller species of waterfowl, with a shorter body and smaller overall body size than most dabbling ducks, and is slightly smaller than its American wood duck relative. The adult male has a small red bill, large white crescent above the eye and reddish face and "whiskers". The male's breast is purple with two vertical white bars, the flanks ruddy, and has two orange 'sail' feathers at the back (modified 12th secondary flight feathers whose enlarged medial vane sticks up similar to boat sails).

Wood Duck
Aix sponsa
The wood duck is a medium-sized perching duck. A typical adult is from 47 to 54 cm (19 to 21 in) in length with a wingspan of between 66 and 73 cm (26 and 29 in). The wood duck's weight ranges from 454–862 grams (16.0–30.4 oz). This is about three-quarters the length of an adult mallard. It shares its genus with the Asian mandarin duck (Aix galericulata). The adult male has stunning multicolored iridescent plumage and red eyes, with a distinctive white flare down the neck. The female, less colorful, has a white eye-ring and a whitish throat. Both adults have crested heads. Voice: The wood duck has distinctive vocalizations that play an important role in communication, particularly during mating season. The male's primary call is a rising whistle, described as "jeeeeee," while females produce several distinct calls including a drawn-out, rising squeal "do weep do weep" when flushed, and a sharp "cr-r-ek, cr-e-ek" as an alarm call.
