Mate choice informed by the immune genes of the major histocompatibility complex (MHC) may provide fitness benefits including offspring with increased immunocompetence. Olfactory cues are considered the primary mechanism organisms use to evaluate the MHC of potential mates, yet this idea has received limited attention in birds. Motivated by a finding of MHC-dependent mate choice in the Leach’s storm-petrel (Oceanodroma leucorhoa), we examined whether the chem. profiles of this highly scented seabird contain information about MHC genes. Whereas previous studies in birds examined non-volatile compounds, we used gas chromatog.-mass spectrometry to measure the volatile compounds emitted from feathers that potentially serve as olfactory infochems. about MHC and coupled this with locus-specific genotyping of MHC IIB genes. We found that feather chems. reflected individual MHC diversity through interactions with sex and breeding status. Furthermore, similarity in MHC genotype was correlated with similarity in chem. profiles within female-female and male-female dyads. We provide the first evidence that volatile chems. from bird feathers can encode information about the MHC. Our findings suggest that olfaction likely aids MHC-based mate choice in this species and highlight a role for chems. in mediating genetic mate choice in birds where this mode of communication has been largely overlooked.Ethyl tetradecanoate (cas: 124-06-1) were involved in the experimental procedure.
