Do you have to cover the bird cage? What are the benifits?
Covering a bird cage is a personal preference. In the wild birds sleep and wake up with the sun (which is why most pet birds wake you up bright and early). Many bird parents choose to cover their bird to block out early morning light, drafts, or so that your bird knows that it is time to rest. However, some birds are afraid of covers. As natural prey, birds are always aware of their surroundings so covering a bird and then making noise around the cage can be upsetting.
If your bird has never been covered and you wish to start using a cover, I recommend starting with a light material and leaving one corner of the cage uncovered so that your bird can still see.
