Copulation occurs in the water with the male approaching a receptive female, who adopts a semi-submerged orientation, with her head stretched outwards and tail raised. The male then mounts the female and clutches the feathers on the lower neck of the female during copulation.
The crest is made up of semiplume feathers: a long rachis with barbs on either side. These are plumulaceous feathers, meaning that they are soft and bendable. In birds, these semiplumes are common along the head, neck, and upper back, and may be used for buoyancy and sensing vibrations. Crests on birds are generally used for display purposes.
