With its nest hidden from view, this water bird feeds on larvae, insects, molluscs and small fish... by walking under water. In March or April, 4 to 6 eggs are placed by the female in a dome-shaped nest made up of moss, dry grass and leaves. After 14 to 16 days incubation by the female, both parents busy themselves for around one month with feeding their chicks, after which they will take flight.
