Zebra finches use volatile compounds for olfactory communication. In this study the volatile composition of zebra finch preen oil and feathers, potential sources of semiochemicals, was studied applying olfactory-guided approaches. In sum, 14 sample pools consisting of 1600 individual samples were analysed. In preen oil, 34 odour-active and 75 further volatiles were detected. In feathers, 51 odour-active and 76 further volatiles were detected. Several substances were common to both sample types, and feathers beared a higher number of volatiles than preen oil. We found hints towards a sex chemical signature. In sum, 121 compounds were identified, out of which 95/49 compounds had not been described in zebra finches/in birds before. This study shows that the combination of classic gas chromatography - mass spectrometry with olfaction-guided approaches leads to a more comprehensive characterization of the avian volatilome. The here presented approach can also be applied for other species.
