I recently got my first bird, a cockatiel about a month ago. He is currently 14 weeks old. We have his cage in our dining room, but it has occurred to me that the dining room (and most of our downstairs) is on the dimmer side. There are ceiling lights in each room, but they are the "soft-white" yellowish light and around 60watts. Do I need to invest in some type of full spectrum or bright lighting to put above his cage, or will he be OK without it? If I do need a light, what type should I get?
