What are some tips for covering a bird cage during the day to provide privacy and security for the birds inside?

To provide privacy and security for birds in a cage during the day, consider using a cover that is breathable and allows some light to pass through. Make sure the cover fits securely over the cage to prevent any gaps where predators could access the birds. Additionally, choose a cover that is easy to remove for cleaning and allows for proper ventilation. It's important to monitor the birds while the cage is covered to ensure they are comfortable and not overheating.
