It will make nests in the tree hole during breeding. Its nest does not have a fixed shape.After doing a good nest, it will lay eggs. The bird's nest can produce 3-6 eggs. After about half a month, the incubation is about half a month. After the young birds are hatched, the pro-bird will start to cultivate the chicks.
