Male canaries usually don't sing much when they molt. The cage must never be in a draft, so do not put it in front of an open window. The bird can overheat in the sun, so make sure at least part of the cage is always shaded if it is at a window. Canary hormones are regulated by daylight length. In the evening, it is best to keep a canary in a dark room, or else cover the cage with a blackout cover.
Canaries are very sensitive to chemical fumes.
They should not be exposed to smoke, room deodorizers, scented candles, bug sprays, oven cleaners, or the fumes from any strong cleaning agents. Teflon and other non-stick polymers will break down if overheated and create toxic fumes that can kill birds anywhere in your home. Avoid using nonstick coated cookware, especially if you keep birds in your kitchen. Toys Canaries are not as playful as parakeets, but they will show interest in mirrors and bells. Generally, any toy that is safe for a parakeet will probably be OK for a canary.
