Hi,
Animal welfare groups often have no idea what birds actually need. While they do not like being in the middle of a room, for example. A pet bird is usually perfectly happy as long as the cage is next to a wall or even in a corner. It is not necessary to keep any part of the cage covered, especially during the day, unless the bird has been abused and has fear issues that are being worked with. Covering parts of the cage can stimulate hormones because it makes it feel like a big nest. Some birds like to have a light cover on their cage at night, but most birds do fine without a cage cover. You need to see what your birds prefer. Birds do like a high perch for sleeping usually, and I recommend having a hanging toy or two next to it, and this can mimic the cover they would get from foliage during the day. Placing the cage by a wall, and not too close to a doorway is best. Birds can get startled if they are right next to a door that people come in and out of. It is better that they can see when someone is entering a room or a door is opening. As for perches, have a variety of sizes – the natural branch type are best, and the type that attach to the side of the cage and don’t go all the way across work great. You are right that they need room to fly. Usually by observing them, you can tell if the cage is too cluttered. But again, they do enjoy having some toys they can sit behind at night or even during the day when napping.
Thank you for asking Lafeber,
