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 to 73 cm (26 to 29 in). This is about three-quarters of the length of an adult mallard. It shares its genus with the Asian Mandarin duck (Aix galericulata). The adult male has distinctive 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. The male's call is a rising whistle, jeeeeee the females utter a drawn-out, rising squeal, do weep do weep, when flushed, and a sharp cr-r-ek, cr-e-ek for an alarm call. Learn more about Wood Duck
