E 11 33' - ALTITUDE: +1100 m. - VOCALIZATION TYPE: full song - SEX/AGE: adult male - COMMENT: Time interval between phrases has been reduced in the song sample (background: woodlark).

The second type is sung in two slightly different ways: compare the 1st and 3rd spectrograms and note that they are composed by respectively 9 and 10 syllables. Mean phrase duration = 1.50 s. (S.D. = 0.09 s.; n=9). Mean interval between phrases: 10.66 s. (S.D. = 3.73 s.; n=7). - MIC: (A)
