The ferruginous duck is a small diving duck; males are rich chestnut with a white eye and undertail, while females are duller with dark eyes. It breeds patchily from Europe and North Africa across Asia and uses shallow freshwater rich in emergent vegetation. Birds dive and dabble for aquatic plants, seeds and invertebrates, nesting close to water in dense cover (Wikipedia, general species account). It is Nationally Near Threatened (Thailand Red Data 2025).
