A male is called a drake and the female is called a duck, or in ornithology a hen. [3] [4] Male mallard. Wood ducks. Taxonomy.
Male mallards also occasionally chase other male ducks of a different species, and even each other, in the same way. [103] In one documented case of "homosexual necrophilia", a male mallard copulated with another male he was chasing after the chased male died upon flying into a glass window. [103] This paper was awarded an Ig Nobel Prize in ...
The wood duck's weight ranges from 454–862 grams (16.0–30.4 oz). [9] This is about three-quarters the length of an adult mallard. It shares its genus with the Asian mandarin duck (Aix galericulata). [2] The adult male has stunning multicolored iridescent plumage and red eyes, with a distinctive white flare down the neck.
Meanwhile, the brightly colored male abandons the female shortly after she begins incubation. Mallards are typically the first — and for many, the only — duck that many people learn to identify.
Pteronetta, Hartlaub's duck – traditionally dabbling ducks, but may be closer to Cyanochen; Cairina and Asarcornis, Muscovy duck and white-winged duck, respectively (2 species) – traditionally dabbling ducks, but may be paraphyletic, with one species in Tadorninae and the other closer to diving ducks
When male and female birds of such species copulate, they each evert and then press together, or "kiss" their respective proctodeum (the lip of the cloaca). Upon the clocal kiss, the male's sperm spurts into the female's urodoeum (a compartment inside the cloaca), which then make their way into the oviduct. [104] [105] clutch
This is a list of the breeds of domestic duck which have official recognition at national or international level. [1]Most breeds of duck derive from the wild mallard, Anas platyrhynchos, while a small minority are descendants of the Muscovy duck, Cairina moschata.
