Black swans may nest at any time of year, although the peak of breeding activity in south-eastern Australia tends to be between June and November. The nest is a large platform of weeds and other debris, about 1-1.5m in diameter and up to 1m high, usually on islands, in shallow water or at the water?s edge. Nests are not generally re-used, but are built from scratch in each new year. The clutch contains between 4 and 11 eggs which are pale green-white in colour, and which are laid at intervals of 1-2 days. Incubation typically commences only when the clutch has been completed, and lasts for 35-40 days. The male and the female both contribute to incubation, with the male typically taking the day shift, while the female incubates at night.
