The nest is composed of leaves, and lined with shredded leaves, dry grass, and feathers. External dimensions of the nest are 17-22 x 14-18 cm, with the entrance having a diameter of 6.5-7 cm and a cavity height of 9 cm. Eggs are white or cream, marked with spotted brown or reddish, marks sometimes more concentrated around the blunt end of the egg. The incubation is 19.5-20 days (Contreras 1988). The chicks leave the nest within four days of hatching (Contreras 1988). Nests have been found in Argentina in late September and October (Contreras 1988).
