The Falcated Ducks have a very intricate courtship ritual. Females perform a series of inciting calls and other movements while preening behind the wings of their targeted male. Males use a courting method similar to others in the Anas genus, including an introductory shake, a neck-stretching burp call, a grunt whistle, and a head-up-tail-up display. During the mating season the falcated ducks form monogamous pairs that last throughout the mating season.
Male – In the breeding season the male Falcated Duck has a dark iridescent green head, neck, crest and collar, bronzed crown, white throat, pale grey breast with black markings, grey body with distinctive elongated tertiaries which are falcated or sickle shaped, and a long dark grey beak.
Female – The female is dark grey-brown with dark streaking.
Eclipse – The male in eclipse plumage is similar to the female but has a darker head and back.

Notes: – The Falcated Duck (or Falcated Teal) is a dabbling duck. It has very distinctive long sickle-shaped (falcated) tertials hanging off its back which give this duck its name. They are hunted for food, and their attractive feathers in China.
The different types of wild ducks can be grouped into puddle, aka “dabbling” and diving ducks. The dabblers mostly feed in smaller bodies of shallow water or along shorelines, where they are able to tip their bodies forward to reach their food on the bottom. There are divers who feed in deeper water where they dive and pursue their quarry. Some of these birds, the Harlequin Duck for example, actually dives to the bottom of fast-flowing waters and feeds on life forms attached to rocks.
