Unless you want a feathered alarm clock in your home, you will want to cover your bird's cage at night so you aren't greeted early in the morning at daybreak. If you cover your bird's cage, your pet will usually remain quiet until your family is ready to start the day.
In addition to more rest for you, covering your bird's cage could be good for your bird too. For instance, a cover at night can shelter your pet from cooler, nighttime temperatures. A cover can also shield light and noise, improving the quality of your pet's nightly rest.
Some owners elect not to cover their birds' cages at all. If you and your pet have a similar waking and sleeping schedule, then you may not need to cover the cage. If you do decide to cover your bird's cage, be sure to do it every night. Birds depend on a routine to feel secure.
The cover you choose must cover the whole cage so that little or no light comes in. Shadows will distract your bird and may even cause apprehension.
Blankets are sometimes used as a cover for birdcages but in addition to looking untidy, this could present a hazard to your bird. For example, your bird might catch a toe in the open weave of a blanket or a person walking past the cage might trip on a trailing blanket end, toppling the cage. For the sake of both safety and appearance, buy a cover made specifically for birdcages. These are available in a range of sizes and colors to suit your bird's cage and your personal taste.
Alternately, if you have a sewing machine and a little talent, it is not difficult to make your own cage cover. Use common sense in selecting a material that will not harm or entangle your bird if your feathered friend decides to explore or chew on it. Choose a closely woven fabric of natural materials. Ideally, use covers that are washable. You should definitely avoid plastics and vinyl.
