The echemes contain 3\u20137 (rarely 2\u20138) syllables with a few microsyllables at the beginning (Fig. 7K). The syllable repetition rate of the macrosyllables is about 6 Hz, distinctly lower than in the other Montana species mentioned above.","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/47544"}]}
