With the likelihood that it is going to spend the majority of its life in a relatively confined space, a bird will need a cage that is as pleasant to live in as possible. A number of factors will determine the overall level of comfort:
Preparation against the cold and drafts: Birds are sensitive to sudden or prolonged temperature changes. So wherever possible try to maintain a steady temperature, while making sure that the bird’s cage is kept away from areas with excessive drafts, like windows and doorways, particularly during the Winter months.
Heat: Oddly enough heat may pose a greater risk to some birds than the cold, especially if the high temperature is accompanied by high humidity. The best preventative measures require that birds be kept away from heaters, not exposed to direct sunlight for too long, and have adequate ventilation available.
Humidity: The best level for humidity is about 40-50%. Lower levels are tolerable, but not under breeding circumstances.
Clean air: As with humans, the quality of air that a bird regularly breathes will effect its health and, more importantly, contribute to a long or shortened life. Smoke, dust and harmful chemicals should be kept well away from the cage.
Cage location: Birds enjoy an area of sociability. A good choice of location would undoubtedly be the living room or a place of recreation.
Daylight and darkness: Try and achieve a good, maintained schedule that balances day-time and night-time conditions for the bird. An irregular balance between the two will result in undue stress and subsequent loss of health.
Hot air ducts: To avoid the risk of an accidentally cooked bird, owners are well advised to keep it clear of all types of heating ducts.
