Canaries in captivity: housing your canary
Canaries are absolutely delightful beings and fun characters to watch.
They tend to be very social beings. A little "friendly" fight here and there with their cage or aviary co-habitants, but generally they get along really well and are non-aggressive. They make very pretty aviary birds - and the melodious song of the males add a lot to the charm of an aviary.
They are never going to be "cuddly pets" and if you handfed some of them from day 1 - they do become quite confiding. They make a great choice for people who enjoy watching birds rather than having a demanding pet that requires a lot of personal attention.
Housing Your Canary:
Since these are birds that will just about always be in a cage, maybe you can give them a roomy flight cage, maybe with some plants in it too for the canaries to enjoy. They should be able to fly. Make it a "project" to prepare an attractive flight cage for them, with lots of toys (no string toys though that might strangle them) and natural branches.
Your canary should be kept in a room with plenty of natural light. Do not place cage near a window where he may get a cold draft. Since a male canary's singing is stimulated by people movements, keep your canary in a room you occupy frequently.
Canaries need plenty of exercise and should be kept in a rectangular cage at least 10 inches wide and 17 inches long.
Be sure to cover your canary's cage at night so the light stops with the sunset. This keeps him in tune with the seasons.
