They nest in hollow tree trunks. The 2-4 eggs are incubated for 27-34 days. The young leave the nest after about four weeks, but will not fly until about six weeks old. The attending parent has been known to attack humans approaching too closely. | They nest in hollow tree trunks. The 2-4 eggs are incubated for 27-34 days.
