“…Divergence in the Middle Spotted Woodpecker happened at a similar timescale to the divergence between the Iberian Green Woodpecker Picus sharpei and Eurasian Green Woodpecker P. viridis (Pons et al 2011, Kamp et al 2019. Their apparently stable contact zone in southwestern France is about 245 km in width with no nuclear introgression detected on both sides of the hybrid zone based on nine Zlinked loci and ten autosomal loci (Pons et al 2019). Although the two Green Woodpeckers differ in coloration of plumage and bare parts as well as in vocalizations (del Hoyo & Collar 2014, Pons et al 2019), evidence for such pronounced differences in morphology between the two lineages of the Middle Spotted Woodpecker is lacking (Cramp 1985) and potential differences in vocalization need to be investigated.…”

“…Coalescence of the Asian and European clades was dated to 1.5 million years ago, a level of divergence found between taxa sometimes treated as distinct species, for instance in the Great Spotted Woodpecker Dendrocopos major and Green Woodpecker Picus viridis complexes (Pons et al . 2011, 2019, Perktas & Quintero 2013, del Hoyo & Collar 2014, Perktas et al . 2015, Gill et al .…”

Deep phylogeographic structure in mitochondrial DNA not reflected in morphological variation has been uncovered in a number of species over the past few decades. However, inferred phylogeographic structure based solely on mitochondrial DNA can be misleading and might not reflect the true history of evolutionary lineages. Consequently, such cases should be further investigated based on genome-wide data. One of these examples is provided by the Middle Spotted Woodpecker Dendrocoptes medius, a nonmigratory habitat specialist associated with old deciduous forests of the Western Palaearctic. It displays strong genetic divergence in mitochondrial DNA between Asian and European populations despite there being only slight variation in morphology between them. Here, we found a clear genomic divergence between Asian and European populations that is consistent with mitochondrial divergence patterns. As revealed by isolation by distance analyses, this differentiation in two lineages was not merely an effect of geography. Genomic population structure indicates that both the Asian and European lineages might each have been separated in more than one refugium during the last glacial maximum. The Middle Spotted Woodpecker might represent a case of cryptic diversity throughout its distribution range, as has been previously found for other taxa across the tree of life. However, we also found footprints of gene flow from the Asian into the European populations, suggesting at least limited introgression upon secondary contact. The processes and mechanisms that might prevent lineage fusion between the morphologically cryptic but genetically divergent lineages of the Middle Spotted Woodpecker need to be further investigated especially in the area of potential secondary contact.

“…In many terrestrial vertebrates of Eurasia, such contact zones typically correspond to biogeographic barriers such as large mountain chains, for example, the Pyrenees (birds: Helbig et al, 2001;Pons et al, 2019;reptiles: Milá et al, 2013;Pöschel et al, 2018), the Alps (birds: Hermansen et al, 2011;toads: Arntzen et al, 2017;rodents: Giménez et al, 2017;Sutter et al, 2013), the Carpathians (newts: Babik et al, 2003;Gherghel et al, 2012;toads: Fijarczyk et al, 2011;Hofman et al, 2007), and the Urals (birds: Shipilina et al, 2017).…”

A plethora of studies have offered crucial insights in the phylogeographic status of Western Palearctic bird species. However, an overview integrating all this information and analyzing the combined results is still missing. In this study, we compiled all published peer-reviewed and grey literature available on the phylogeography of Western Palearctic bird species. Our literature review indicates a total number of 198 studies, with the overwhelming majority published as journal articles (n = 186). In total, these literature items offer information on 145 bird species. 85 of these species are characterized by low genetic differentiation, 46 species indicate genetic variation but no geographic structuring i.e. panmixia, while 14 species show geographically distinct lineages and haplotypes. Majority of bird species inhabiting the Western Palearctic display genetic admixture. The glaciation cycles in the past few million years were pivotal factors in shaping this situation: during warm periods many species expanded their distribution range to the north over wide areas of Eurasia; whereas, during ice ages most areas were no longer suitable and species retreated to refugia, where lineages mixed.
