Song: During display males produce a nasal grating "kaaKAA...kaKAA" higher pitched than calls of Ring-necked Duck, very different from Common Goldeneye. Female's guttural "guck" almost identical to female Common Goldeneye's call but slightly higher pitched. Wing whistle is quieter and less whining than Common's.
Sound: Robert C. Stein (Macaulay Library, Cornell # 3711); 1958 Jul 9; Canada, British Colum"
