The Common Pochard finds its habitat in diverse wetland environments, such as marshy lakes, reed-fringed reservoirs, and sometimes coastal areas during winter. Its range spans across North America, Europe, Asia, and Africa, demonstrating adaptability to different aquatic habitats.

The behavior of Common Pochards often involves joining winter flocks of Tufted Ducks, emphasizing their ability to survive in various environments. They prefer to dive for forage, feeding on small fish, insects, and plant matter.

Despite a population estimate of 1,950,000-2,250,000 individuals globally, there is a troubling trend of decline, especially in Europe. The Common Pochard's tendency to hybridize with other diving ducks, such as the Tufted Duck, complicates their conservation status.

Preservation of the diverse habitats that Common Pochards inhabit is key to their long-term survival.

Distinctive Red Head and Bill

The Common Pochard, a diving duck species, is easily recognized by its red head and distinct bill. The male of the species is marked by a dark rusty head and a light blue band on the bill, distinguishing it from other duck species. The female Pochard, on the other hand, displays a gray-brown plumage, a sloping forehead, and a dark gray bill with a light band near the tip.

However, the Common Pochard population has been decreasing, largely due to habitat loss, pollution, and hunting pressure. These threats have placed this striking species at risk, underlining the urgency of conservation efforts. The distinctive red head and bill of the Common Pochard serve as a vivid symbol of the species' beauty and singularity, underscoring the need for its preservation.
