TL;DR: Emergent trends and gaps in understanding are identified, new approaches to more fully integrate genomics into speciation research are proposed, and an integrative definition of the field of speciation genomics is provided.

TL;DR: It is concluded that the heterogeneous landscape of differentiation in Ficedula flycatchers evolves mainly as the result of background selection and selective sweeps in genomic regions of low recombination, and the necessity of incorporating linked selection as a null model to identify genome regions involved in adaptation and speciation is emphasized.

TL;DR: Higher nucleotide diversity in the avian genome could be due to the relatively older age of flycatcher populations, compared with humans, and/or a higher long‐term effective population size.

TL;DR: It is shown that, paradoxically, pairing with another species may offer the best fitness return for an individual, despite reduced fitness of hybrid offspring, and appears to represent adaptive mate choice under some circumstances.

TL;DR: It is demonstrated that species recognition is inherited on the Z chromosome, which is also the known location of species-specific male plumage traits and genes causing low hybrid fitness, suggesting that the sex chromosomes may be a hotspot for adaptive speciation.
