The male common pochard has a chestnut head, black breast and pale grey body; the female is brown with a darker crown. It breeds across Europe and Asia and migrates to milder lakes and wetlands in winter. Flocks dive for aquatic plants, seeds and invertebrates, often feeding at night and resting together by day on open water (Wikipedia, general species account). It is Nationally Vulnerable (Thailand Red Data 2025).
