Examples of longsong audio spectrograms from clades A‒F of the Megascops atricapilla-M. watsonii complex. (A) Clade A: Venezuela, Rio Cuyuni (Paul Schwartz, ML 59376); (B1) Clade B: Peru, Madre de Dios (Ted Parker III, ML 11496 = locality B26 in Fig. 1); (B2) Clade B: Venezuela, Rio Cassiquiare (Paul Schwartz, ML 59397 = locality B23 in Fig. 1); (C) Clade C: Brazil, Serra dos Carajás (Sidnei Dantas, XC 22514); (D) Clade D: Brazil, IPEAN, Belém (Paul Schwartz, ML 59395); (E) Clade E: Brazil, Usina Serra Grande, Ibateguara, Alagoas (Curtis Marantz, ML 127980); (F) Clade F: Brazil, Caetetus Ecological Station, São Paulo (Alexandre Aleixo, ML 94909). Each sonogram is typical of a given clade, except for Clade B, where a slow-paced song (less than 4 notes/s), and a fast-paced song (more than 6 notes/s) are shown. The slow-paced individuals are all from the south bank of the Amazon River, while most of the fast-paced Clade B specimens come from north of the Amazon, except for some samples from the lower Inambari and Rondonia areas of endemism in Brazil (see Fig. 9).
