Nest: It is lined with plant matter. Young precocial; leave nest 18-24 hours after hatching. Tended by both sexes for at least 144 days. Possibly 2 broods per year. "Dump" nests produced by more than one female laying eggs in a single nest are common, which results in documented neests containing more than 100 eggs. Will nest in tree boxes.
Eggs: 12-16 white eggs without a nest lining in a tree cavity or artificial nest box, occasionally on the ground among reeds.
Incubation: 25-30 days by both male and female, but primarily by male.
