The table shows retention indices (RI) on a DB-FFAP and a DB-5 column, CAS-numbers, fulfilled identification criteria and previous reports. Identified compounds are marked in bold. RI, retention indices from internal database established with reference compounds; i, identified by comparison of RI and match with a reference compound on two columns (DB-FFAP, DB-5) via AMDIS; t.i., tentatively identified by comparison of RI and match with a reference compound on a DB-FFAP or a DB-5 column via AMDIS; n.a., not available; s.d., elution within solvent delay; ^BPotential contaminant of exogenous origin because substance was also present in the blank sample; *co-elution of two compounds; X, unknown compound detected. Substances that have been reported before in bird odour are marked with a ‘y’ in the far right column. For each adsorbent type, a substance is mentioned as (tentatively) identified if it was detected in > 2 samples
