=Description.= Ordinary fowls are rather small land birds. The males at maturity weigh from four to five pounds each, and the females about a pound less. They are plump, rugged, and very active. If treated well they are bold, and with a little attention can easily be made very tame. If neglected and abused, they become shy and wild. The most striking peculiarities of the fowl are the fleshy comb and wattles which ornament the head, and the full tail which is usually carried well up and spread perpendicularly. The head appendages vary much in size and form. They are sometimes very small, but never entirely wanting. The carriage of the tail also varies, but except in a few breeds bred especially for low tails it is noticeably high as compared with that of other poultry. Fowls are readily distinguished from other birds by the voice. The male crows, the female cackles. These are their most common calls, but there are other notes--some common to both sexes, some peculiar to one--which are the same in all races of fowls. An abrupt, harsh croak warns the flock that one of their number has discerned a hawk or noticed something suspicious in the air. A slowly repeated cluck keeps the young brood advised of the location of their mother. If she finds a choice morsel of food, a rapid clicking sound calls them about her. When she settles down to brood them she calls them with a peculiar crooning note. The male also cackles when alarmed, and when he finds food calls his mates in the same way that the female calls her young under the same circumstances. Other poultry and sometimes even cats and dogs learn this call and respond to it. If the food discovered is something that a stronger animal wants, the bird making the call may lose it because of his eagerness to share the treasure with the members of his family.
