Account

What the sources say about this taxon, as written.

behaviour · bio.acousti.ca

The calling song consists of a long sequence of echemes, each usually lasting baout 1-4 s, composed of about 25-90 macrosyllables and often ending with 2-5 microsyllables. Within one song echemes are usually fairly uniform in duration and are usually separated by intervals of about 4-10 s. Oscillographic analysis shows that opening hemisyllables are usually absent and that the closing macrosyllable susually last about 20-85 ms and are repeated at the rate of about 10-30/s. The microsyllables usually last about 1-12 ms and are repeated at the rate of about 20-40/s; the microsyllable sequence at the end of an echeme seldom lasts more than 0.2s. The echemes usually begin quietky, reaching maximum intensity by the third to seventh syllable, and the first one or two syllables are usually shorter than the remianing ones.
