Contact zone characteristics contribute to patterns of divergence in lineages of the Brown Creeper (Certhia americana)

Spatial sampling and genomics can be used to infer the history of hybridization in contact zones. In this study, two putative hybrid zones – one geographically expansive and the other confined to the Black Hills – between three lineages of a widespread North American songbird, the Brown Creeper (Certhia americana), are compared to investigate regions of genetic differentiation and explore their effects on signatures of admixture. This study confirms the existence and origins of putative chromosomal inversions, identifies two new regions of differentiation, and discovers a possible hybrid lineage
