Nutrition and behavior
The diet is based on molluscs, sprouts, berries and seeds found in water. In captivity it needs a varied diet. Feeding captive babies requires special attention.
The couples that isolate themselves from the group, nest in rocky ravines. The number of eggs generally varies from 8 to 12 and the hatching lasts 23 days. In captivity, especially if the environment is not sufficiently peaceful, hatching is often not completed (incubator and subsequent artificial breeding without the mother are necessary).
