Range (breeding: green and blue; wintering: orange) with location and number of samples assayed of black scoter (a, d), surf scoter (b, e), and white‐winged scoter (c, f) in North America using double‐digest restriction‐associated DNA sequence (ddRAD; a–c) and microsatellite genotype (msats; d–f) methods. Sample locations representing breeding areas are designated with solid circles and nonbreeding locales with dashed circles. Blue represents newly identified breeding areas (see Sea Duck Joint Venture, 2015)
