Abstract :
A rebuttal is presented to the article of L.N. Frazer and E. Mercado (ibid., vol. 25, pp. 160-182, 2000), who presented a sonar model for humpback whale song, is presented. This rebuttal considers the noise-limited form of the sonar equation, current understanding of humpback whale behavior and the characteristics of humpback whale songs, along with arguments from an evolutionary perspective. Arguments from all of these different aspects do not support the model of Frazer and Mercado
