Lesser Scaup

Aythya affinis


Medium size duck. Black, gray and white body with a iridescent bluish green head with a blue beak and yellowish orange eye.


Marsh ponds (summer), lakes, bays, estuaries. Summers around large marshes in prairie or forested regions. Winters on lakes, reservoirs, rivers, sheltered areas of coastal bays. Overlaps extensively with Greater Scaup, especially in winter, but at that season the Lesser is far more likely to be found on freshwater lakes and ponds well inland.
