For one bird, the cage should not be less than 9½ inches long, 6½ inches wide, and 9 inches high. A larger size is to be preferred. The ordinary cages obtained from dealers in this country are made of wire and are open on all sides. Each is fitted with receptacles for food and water, usually at opposite ends. A fine-mesh wire screen may be bought from the dealer and fastened around the lower half of the cage to prevent the scattering of seeds and seed hulls. A common substitute for this is a simple muslin bag, held in place by a drawstring fastening tightly about the middle of the cage.

In a cage of ordinary size three perches are sufficient. One may be placed at either end at a distance that will allow easy access to the food and water receptacles, and the third elevated above the middle of the cage at its center. Another convenient arrangement is to run one perch lengthwise of the cage, in such way that the bird may reach the feeding receptacles from it, and to place the two other perches transversely above it near either end. A bird confined in small quarters is dependent for exercise on hopping about from perch to perch, and this arrangement will give the maximum freedom of movement. In larger cages four perches may be advisable. These should not be placed so that they interfere with the free movement of the bird, and for reasons of cleanliness one perch should not be directly above another. In small wire cages, if the swing perch usually found suspended in the center is removed, the bird will have more room, and in hopping back and forth will not be continually striking head or wings. In larger cages this perch may remain. Perches should be large enough for the toes of the bird to grasp them readily and encircle them for three-fourths of their circumference. If they are too small they cramp the foot, while if too large they may cause malformed toes or claws, especially in young birds. Perches should be elliptical in shape, about three-eighths of an inch in the long diameter, which should be horizontal. If those furnished with the cage do not meet these requirements, others may be made from soft wood without much trouble.

Cages in which canaries are to breed must be large and roomy in comparison with those intended for single occupants. An English authority gives the standard size for breeding cages as 22 inches long, 12 inches wide, and 16 inches high. Several types of open breeding cages made of wire may be obtained, or a box with a removable wire front may be made. If it is planned to use wooden cages for several seasons they should be enameled or whitewashed inside to permit thorough cleaning. Such cages should be smooth inside and any with cracked or warped boards should be avoided, as crevices may harbor dirt or mites. Though cages may be made of wire screen this is not advised, as cages so constructed become very dirty, and there is danger that birds may catch their claws in the wire and become injured.

Where numbers of canaries are kept box cages with wire fronts are convenient, as they may be placed in racks one above another or arranged on a series of shelves along the wall of the bird room. They are provided with a sand tray three-fourths of an inch deep that slides in and out from the front and facilitates cleaning. Perches for these cages may be adjusted in the following manner: One end is notched and the other has a brad driven in it filed to a sharp point. The sharpened brad is pressed against the back of the cage and a wire on the front is slipped into the notch. If made the right length the pressure of the wire will hold the perch in position.

For shipping birds the small wicker cages in which canaries come to dealers are best. These are fitted with deep, narrow-necked food and water receptacles that do not readily spill, so that there is a minimum of waste during the journey. A small packet or sack of seed should be tied to the outside of the cage in order that the bird’s supply may be replenished en route.

CARE OF CAGES.

Though canaries when acclimated can endure a great degree of cold without discomfort, they are susceptible to sudden changes in temperature, and cold drafts may soon prove fatal. This should be borne in mind in choosing a place for the cage. Direct exposure to a strong draft of cold air must always be avoided. A cage may be placed on a small shelf along the wall or suspended from a bracket attached to the wall or window casing. Swinging brackets are inexpensive and are convenient for use when it is impracticable to fasten hooks in the ceiling. When one or two canaries are kept as pets, it is usual to suspend their cages before a window, where the birds may enjoy light and sunshine, a good practice where the window is kept closed during cool or stormy weather and the joints are tight. It may be necessary to line the edges of the window frame and the junction of the upper and lower halves of the window with weather stripping to prevent drafts, and it is best to suspend the cage so that it will hang opposite or below the junction of the two halves of the window frame. The room must remain at a fairly even temperature day and night, and in cold weather it is well to cover the cage with a towel or other light cloth at night. A cage should never be suspended directly above a radiator, and it is best to avoid keeping birds in small kitchens, as the fluctuations in heat are perhaps more marked there than in any other part of the house. Exposure to damp air may prove fatal, another reason for avoiding the steam-laden air of small kitchens.

Wherever placed, the cage must be kept scrupulously clean if the canary is to remain in good health and free from vermin. The supply of water should be renewed daily, and the seed cup replenished at least every other day. The receptacles for these necessities should be cleaned and washed carefully at short intervals. Cages that have removable bases should have the tray in the bottom covered with several thicknesses of paper, or the heavy coarse-grained sandpaper, known as gravel paper, that may be secured from dealers in cage-bird supplies, may be used. This should be renewed whenever the cage is cleaned, and in addition the pan should be washed in hot water from time to time. Lime on the perches may be removed by means of a scraper made of a bit of tin fastened to a wire or tacked at right angles to a stick small enough to pass easily between the wires of the cage. Cages with bottom attached should be provided with a sand tray that slides in and out through a slot in the front. This serves to catch droppings, seed hulls, and other waste, and may be easily pulled out, cleaned, and refilled with fresh sand.

INDOOR AND OUTDOOR AVIARIES.

Those who keep birds for pleasure, and who do not care to breed them for exhibition or to maintain any particular standard, may receive much enjoyment from aviaries in which numbers of canaries are kept in one inclosure. The size of the aviary or bird room will be governed wholly by circumstances, as it may range from an entire room to a small screened inclosure or part of a conservatory. A room large enough for the owner to enter without unduly frightening the occupants makes an ideal indoor aviary, and where space permits it may be fitted up without great expense. The floor should be covered to the depth of half an inch to an inch with clean sand or sawdust. Small evergreen trees planted in large pots furnish suitable decorations, and may be replaced from time to time as they are destroyed by the inmates of the aviary. A branching dead tree and one or two limbs nailed across corners at suitable heights furnish more artistic perches than straight rods. In addition, pegs 4 or 5 inches long may be driven or nailed to the walls to furnish resting places.
