Hi, I'm Laurian Rauen from Wing to New Horizons, a nonprofit bird sanctuary, I'm going to show you how to prepare a cage so that your parakeet can rest peacefully at night. It is a very simple concept, you can use any one of different material. This happens to be a beach towel and basically the bird likes to have twelve hours of darkness at night. So what you're going to do is you're going to drape this around the cage, around the front, across the top and that's as simple as it gets. You can either use this or a sheet, or if, depending on the temperature inside of the room. If it is not in an area that is well ventilated, what you might want to do is leave the bottom open so that air can get through. What you might want to do is you might want to pull the one side up. You want to, you don't want to have it totally, I personally believe that there should be an area where it is open, because then if the bird, say in the morning, you forgot to uncover me, the bird's going to be down here and the bird's going to be talking to you, saying, whatever, come on, it's time to pull this off. If you have a pillowcase that's a large enough size for your cage, yes, you can slip a pillowcase over it. I prefer the towel because, trust me, the birds might find it a little bit offensive and they are going to peck at it, and they are very likely going to destroy it, so don't use something that you highly value.
