Corncrake calls were recorded at three sites in Poland and one in the Czech
Republic Recordings were made during the corncrake breeding season, from 8 to
30 July, in 2011 and in 2012. Males were recorded when calling spontaneously,
in favourable conditions, at night (from 22.00 to 03.30, local time) from a
distance of ca. 5-10 m. The original dataset comprised 104 males with 10
calls measured from each male.
Formants (second to fifth) were measured within the first syllable of the
call. Formants were extracted by PRAAT.
