The mallard is one of the most recognized of all ducks and is the ancestor of several domestic breeds. Its wide range has given rise to several distinct populations. The male mallard's white neck-ring separates the green head from the chestnut-brown chest, contrasts with the gray sides, brownish back, black rump and black upper- and under-tail coverts. The speculum is violet-blue bordered by black and white, and the outer tail feathers are white. The bill is yellow to yellowish-green and the legs and feet are coral-red. Male utters a soft, rasping kreep.
