The Wood Duck is a medium-sized perching duck. A typical adult is from 47 to 54 cm (19 to 21 in) in part with a wingspan of between 66 to 73 cm (26 to 29 in). This is about three-quarters of the part of an adult Mallard. It shares its genes with the Asian Mandarin Duck (Aix galericulata). wood_duck.mp3 (200 downloads)
