The Ferruginous Duck (Aythya nyroca) is a medium-sized diving duck recognized for its rich chestnut-brown or ferruginous plumage, with males having a glossy, dark brown head and body, while females are slightly duller in color. This species has strikingly white undertail feathers and eyes, providing a sharp contrast that makes it easily identifiable in the water. Preferring calm freshwater habitats like lakes, marshes, and slow-moving rivers, the Ferruginous Duck is primarily found in Europe, Asia, and parts of North Africa. It feeds by diving for plant matter, insects, and small aquatic animals, showing strong adaptability to different diets based on available resources. Unfortunately, this beautiful duck is considered Near Threatened due to habitat loss, hunting, and environmental pollution, making conservation efforts critical for maintaining its populations.
