They usually build the nest in the tree cave, and there are some grass roots, straw stems, grass leaves, etc. inside.After the nest is built, the female birds begin to lay their eggs. Each nest will produce 3-6 pieces. The color of the egg is blue-green and the surface is shiny.Its incubation period is 16 days. After the chick came out of the shell, it can leave the nest after two weeks of feeding.
