Additional file 1: of Vocal exchanges during pair formation and maintenance in the zebra finch (Taeniopygia guttata)

Audio examples of the call repertoire of the zebra finch. (same pair as Fig. 1). Five calls for each sex and call type are spaced by one second silences. We randomly selected calls to be presented from the ones not containing noise. Sounds were recorded with backpack microphones and their amplitude normalised to -0.1 dB (maximal sample value).
