Wood duck is probably the most stunningly colorful waterfowl in the world. The male bird has a metallic, purplish-green head and crest. Their belly is white and chest is dark-red. Along the neck, they have attractive, narrow white stripes. Their wings are patterned blue and black. 
Female wood ducks are not so colorful as males. They have grey-brown head, white belly and white speckled breast. Male bird uses their colorful plumage to attract female bird during breeding season.
Beautiful. Up vote and follow done.
