Breeding

Nest: Builds a large stick and reed nest on the ground near shallow water (Stonor 1939).

Eggs: White eggs with pale spots and granulated shells (Stonor 1939).

Clutch size: Southern Screamers can lay between 2-7 eggs, but 3-5 is the most common. The chicks hatch with a thick gray-yellow down (Stonor 1939).

Incubation: Incubation can range from 43-46 days. Fledging can take anywhere from 8 to 10 weeks and are completely independent between 12 to 14 weeks (Stonor 1939, Weller 1967).

Parental care: Both the male and the female incubate the eggs and once they hatch, both parents watch over them. The young are nidifugous; they are only brooded for the first few days. The young are very good swimmers (Stonor 1939).

Other: Southern Screamers will keep their breeding territory. Eggs generally are laid in October and November (Stonor 1939).
