Identification and description:
The Lesser Scaup, Aythya affinis, is a medium-sized diving duck known for its rounded head and grayish plumage. Males have a black head with purple sheen, gray back, and white belly, while females are duller with a brown head and a white ring around the bill. They primarily feed on mollusks, crustaceans, and aquatic plants. Their preferred habitats include lakes and ponds in North America, where they migrate in large flocks. Their flight is fast and direct, often in tight formation. Although common, their population is monitored due to environmental changes.
Recommended lens:
400mm – adjust based on distance, desired framing (portrait or habitat), and approach conditions.
Photography tips:
To photograph the Lesser Scaup, it is advisable to use a telephoto lens of at least 400mm to capture detailed images without disturbing the bird. Approach slowly and maintain a safe distance of about 10 m to avoid startling it. The best photo opportunities often occur early in the morning or late afternoon when the light is soft and bird activity is high. Be patient and wait for the bird to adopt a natural posture or interact with its environment to get authentic shots.
