Since male singers respond best to a well-lighted location, find a place in your home in which you spend most of your day. Most people seem to choose their kitchen or breakfast area. In any case, the room chosen must have a window that allows the bird to see the passage of the day. If the window gets too much sunshine, place the cage about halfway in so so the canary can go the shaded side of his cage whenever he chooses. Make sure you place your bird away from the draft of a door or air vent.
I like to place the cage at eye level as I feel the bird feels a little safer higher up. If you are breeding the birds, the location should provide plenty of privacy. Some hens are afraid to get off the chicks to feed them if there is too much commotion going on. You should also observe the male at this time. Sometimes the hen is afraid the male may hurt the chicks. In this case, she remains on the nest. Quite often though, you do see the male feeding the hen and she then feeds the chicks. Do not be surprised to see the male at times sitting on the nest while the hen is away. Those are the little fathers that just make this hobby so much fun!
Don’t try to breed birds in a busy location as they need to feel secure and have a sense of calm and privacy. You can put a tea towel over the part of the cage where the nest is located to offer her more privacy. Make sure the birds are not in the direct line of an air conditioning vent. Canaries can adjust to cold temperatures but not a cold draft. The perfect temperature is 74 degrees. Sudden spikes in temperature are not good for birds. Make sure you protect them from extreme cold and heat. Certainly, do not place birds where the door opens all the time and allows a cold draft. You must also not put your birds outside where mosquitoes will bite them.
