Before taking up a description of the matings of the different standard breeds and varieties it is well to indicate the common nomenclature which is used in connection with these fowls and which differs from that used for chickens. The male duck is called drake, the female duck is termed duck, and the young duck of either sex is termed duckling. In giving the standard weights for the different breeds of ducks, weights are given for adult ducks and adult drakes, and for young ducks and young drakes. By adult duck or drake is meant a bird which is over one year old. By young duck or drake is meant a bird which is less than one year old. The horny mouth parts of the duck instead of being termed beak as in chickens are called bill, and the separate division of the upper bill at its extremity is termed the bean. Ducks do not show any comb or wattles as in chickens. In England use is made of the terms ducklet and drakerel. Ducklet is used to signify a female during her first laying season just as the word pullet is used in contrast to hen. Drakerel is used to signify a young drake as contrasted with an older drake just as the word cockerel is used in comparison to cock in chickens.

Distinguishing the Sex. The sex of mature ducks can be readily told by their voices and also by a difference in the feathering. The duck gives voice to a coarse, harsh sound which is the characteristic "quack" usually thought of in connection with this class of fowl. The drake on the other hand utters a cry which is not nearly so loud or harsh but which is more of a hissing sound. Distinction of sex by this means can be made after the ducklings are from 4 to 6 weeks old. Before this age, both sexes make the same peeping noise.

Mature drakes are also distinguished from the ducks by the presence of two sex feathers at the base of the tail. These are short feathers which curl or curve upward and forward toward the body of the bird. In ducks these feathers are absent.
