Mandarin courtship display is very impressive and includes mock-drinking and shaking. Pairs are formed at the beginning of the winter and may continue for many seasons. Although the female chooses the exact nesting site, the male accompanies the female on nest searches. Nest are alway in a hole in a tree and can be up to thirty feet from the ground. In preparation for egg laying, the female lines the nest is with down. Clutch sizes range from nine to twelve white oval eggs that are laid at daily intervals. Incubation is solely performed by the female and last between 28 and 30 days. When all the eggs are hatched (they hatch within a few hours of each other), the mother calls to the chicks from the ground. Each chick then crawls out of the hole and launches itself into a free fall. Amazingly, all the chicks land unhurt and are en route to the nearest feeding ground. Once the chicks are able to fly (after 40-45 days), they leave to join a new flock.
Range eggs per season: 9 to 12.
