Miracle, there is no way Timber could get enough natural light "naturally" considering our home's location, the weather, and the window set up. I ordered an avian light and put it on a timer for him. He really seems to like it. When he is out, he will get on the perch atop the cage and sit right under it and preen. When he is in the cage (which he usually isn't if I am home but I watch him on a cam) after he has eaten, foraged, played or whatever he positions himself right under the light to nap or preen. The point I'm trying to make is that an avian light is a good choice if you can't get their 15 minutes of sunshine a day in!
