baer's pochard
Aythya baeri
Baer's pochard is a rare medium-sized diving duck. Males have a black head with a green sheen and white eyes, while females are more modestly colored in brown tones.
Baer's pochard differs from related species by the white eyes of males and a special pattern on the sides. It is important for nature as a consumer of aquatic plants and invertebrates and as part of the food chain in freshwater bodies.
