E 2828' - ALTITUDE: 100 m. - VOCALIZATION TYPE: three different call types. - SEX/AGE: unknown - COMMENT: this audio sample is part of a longer recording (to check the editings, see spectrogram time axis). Note that the third call type (see spectrograms) is a clearer mimicry of sparrow call compared to Recording 3. Background: wind noise. - MIC: (P)

RECORDING 5
DATE/TIME: 24/june/2014 (8.10 a.m.) - IDENTIFICATION AND BEHAVIOUR: same place as above and same bird. - POSITION: Niculitel, Tulcea district, Romania, LAT. N. 4212'/LONG.
