This is a door that opens into a small alcove, or entry way. The first door is closed, then the second door is opened into the aviary. Access doors for nest boxes and feeding dishes may make maintenance easier. The number of perches and feeding dishes for your aviary varies by the number of birds. For perches, an aviary provides a wonderful opportunity for design.
Plants become natural perches that simulate a bird's environment.
Store bought perches may also be used. For each bird, you will need at least 3 inches of perch, and for larger, or more aggressive species the number can be increased. Ideally, each bird should have its own perch. Several birds, provided that they eat the same general food mix, can eat out of the same dish. Large terra cotta plant saucers work great for this.
