How do Crested Ducks feed?

What are Crested Duck birthing rituals like?
The breeding season for the Patagonian Crested Duck is between October and December. Crested Ducks build their nests in shallow coastal regions or near ponds, hiding them in tall grass or foliage.
The nests are made from the surrounding vegetation and lined with feathers.
The female will lay between 5 and 8 eggs per clutch. The eggs weigh around 56 grams. The female takes on the incubation duties, the incubation period lasting about 1 month.
Once the eggs hatch both parents will tend to the ducklings. The chicks will begin to fledge (grow their adult flight feathers) when they are about 10 weeks old.

Crested Ducks live an average of 20 years in the wild.
