White-faced whistling duck

Breeding in the white-faced whistling duck usually begins at the start of the rainy season and peaks when wetlands are at their most flooded. Timing varies by region, since the species is found in South America and across much of Africa, on both sides of the equator.

The species is monogamous, and pairs appear to form long-lasting bonds.

Nests are built on the ground, well hidden in tall grasses or reed beds. They are sometimes placed right near the water but can also be up to a kilometre away. Made of vegetation (leaves and stems) with no down lining, the nest is about 20 cm in diameter.

Clutches typically contain 4 to 13 eggs (sometimes up to 16), creamy white to pale pink. Females usually lay one egg per day. Both parents incubate the eggs for 26 to 30 days.

The ducklings, dark brown above and yellow below, leave the nest about 48 hours after hatching. They stay with the family group long after fledging, which occurs between 60 and 83 days. The species can breed as early as one year of age.
