In the north of the country it is in March to May, in southern and central Queensland December and January, and October to December in the south. Located atop trees at a height of 20 m (60 ft) or more, the nest is a flat wide platform of dry branches and sticks with a shallow basin for eggs and young. The clutch consists of anywhere from two to six pale blue-green eggs, with three or four being the usual number. They are oval in shape and measure 52 X 36 mm.
