The female builds a large, shallow cup of twigs, grass, bark strips, rootlets, leaves, and lichen, lined with moss, plant down, hair, and feathers. 3 to 4 eggs are laid and incubated by the female for about 13 days. She is fed by the male. The young leave the nest after 13 to 17 days, and the parents continue to feed the young for about three more weeks.
