Song: Trill in two parts: the first slow, high-pitched, staccato, and distinctly two-syllabled, the second fast, short and lower in pitch: "tsi-bit-tsi-bit-tsi-bit-trrrr". Pattern is similar to Wilson's and Yellow-rumped Warbler's but quality of Nashville song is distinctive.
Sound: Monty Brigham (Bird Sounds of Canada); 1973 Jun 20; Canada, Québec; Lac Cayamant; Adult; Primary Sound;
