The hen lays 4-7 eggs, one every other day, which she incubates for 17–23 days. The chicks fledge after 5 weeks. [18] Cockatiels are the only cockatoo species which may reproduce by the end of their ...

This female then departs, leaving the male to care for the clutch while she repeats the process with another male. Species which exhibit this behavior include certain types of red and red-necked phalaropes, and spotted sandpipers which breed in South America. (Paul R. Ehrlich, David S.
