Sonogram of a common coot call to demonstrate how parameters were measured for each syllable. The parameters included peak frequency (PF), fundamental frequency (F0), maximum frequency of fundamental frequency (F0max), minimum frequency of fundamental frequency (F0min), duration of syllable (T), and interval of syllables (TI). Amplitude spectra of the left syllable show high energy in the third harmonic (PF)
