2. Place the nesting box in the cage. The nest box should be placed in a quiet, private area of the cage. It should be high enough off the ground so that the cockatiels can easily reach it, but not so high that they feel insecure.
3. Provide the cockatiels with nesting material. Cockatiels will use a variety of materials to build their nest, including twigs, leaves, and grass. You can provide them with these materials by placing them in the cage or by hanging them from the top of the cage.
4. Introduce the cockatiels to each other. If the cockatiels have not already been introduced to each other, it is important to do so before you try to get them to mate. The best way to introduce them is to place them in a neutral environment, such as a large cage or aviary. Let them spend a few days together so that they can get to know each other.
5. Encourage mating behavior. There are a few things you can do to encourage mating behavior in cockatiels. One is to provide them with a variety of foods that are high in protein, such as seeds, nuts, and fruits. Another is to mist them with water several times a day. Finally, you can play music for them that has a high-pitched, melodious sound.
6. Be patient. It may take some time for the cockatiels to mate. If they do not mate within a few months, you may need to try a different approach.
