Have a habit of hiding nuts of tree in hollows of trees. The breeding season is from May to July. Male chirp slowly sounding like “ hitcho ci choo” and “tu pi tu pi tu pi” for announcing their territory. Nest by digging a hole in half-dead tree and cover the floor with soft materials like soften barks. Lay five to eight eggs in a sesason.
