The nest is a pad of green moss, mossy fibers and rhododendron leaves, placed above ground in tree cavity, usually in oak. The hole if too large may be “plastered” up with mixture of mud and berries. They lay a clutch of 4–7 eggs. The incubation of eggs and feeding of chicks are done by both sexes.
