=Place in domestication.= Most people who have canaries keep them for pets, and have only a few. In perhaps the greater number of cases a single bird--a singer--satisfies the canary lover. A few of those who keep canaries as pets also breed them for sale. Occasionally a canary fancier devotes a room in his house entirely to his birds and, when breeding on such a scale, has a great many to sell. The commercial side of canary breeding, however, is usually subordinate, except in the Harz Mountain district, where the breeding and training of singing canaries is a very important cottage industry. Canaries from this district are sold all over the civilized world. [Illustration: Fig. 224. English Flatheaded Canary] MANAGEMENT OF CANARIES =Cages.= The common wire bird cages used for one or two canaries are so well known that no description of them is necessary. For larger numbers larger cages must be provided. Large cages cannot always be obtained at stores which sell the small ones, but they may be obtained from bird stores in the large cities, or made to order by a local mechanic. Indeed, any clever boy who has learned to use tools can make one at very little cost. While the small cages are usually made all of metal, the large ones are commonly made with wooden frames. A small cage has a removable bottom. A large cage must have two bottoms--the outer one fixed, the inner one in the form of a movable drawer. A metal drawer is easier to keep clean than a wooden one. =Position of the cage.= The cage in an ordinary room should be hung where its occupants will be comfortable and safe. The greatest foe of the domestic canary is the house cat. Some cats can be trained to let canaries alone, but very few can be trusted to make no attempt to get a canary when left alone in a room with it. When canaries and cats are kept in the same house, the cage should hang in a place from which cats can be excluded when they cannot be watched. The comfort of the bird will often require that the position of the cage be changed once or oftener during the day, according to the season or to some particular condition. Thus, a sunny window may be very pleasant at some times and too warm at others, or a bird may tire of being constantly in the same place. The bird keeper has to learn to know, by observing the actions of birds, when they are comfortable and contented, and must use judgment in placing the cage to suit them.
