Platycleis romana

The calling song consists of a mixture of short echemes usually lasting less than 0.5 s and composed of fewer than 10 macrosyllables, and longer echemes lasting up to 3 s and composed of 15-80 macrosyllables. Each echeme usually ends with a series of p to 10 microsyllables. Oscillographic analysis shows that quiet opening hemisyllables are often present; the closing macrosyllables last aboyt 20-30 ms and are repeated at the rate of about 25-40/s. The closing microsyllables last about 2-3 ms and are repeated at the rate of about 35-50/s; the microsyllable sequence at the end of an echeme usally lasts less than 0.3 s. The echemes usuallybegin quietly and the first one or two syllables are often shorter than the reaming ones. The intervals between echemes vary from less than 1 s to more than 4 s. [1]
