The taxonomic status of six subspecies of Greenish Warbler Phylloscopus trochiloides was re-examined in the light of fresh evidence about their identification characters and biological relationships.Although P. t. viridanus and P. t. plumbeitarsus (‘Two-barred Greenish Warbler’) behave as distinct species in their zone of overlap, the five subspecies viridanus, ludlowi, trochiloides, obscuratus and plumbeitarsus form a cline within which it is not possible to define species boundaries.There is…

Cryptic species in the genus Phylloscopus (Old World leaf warblers)
TLDR
Estimated relationships within the species complex based on mitochondrial control region DNA sequences show that there is little variation within the geographic ranges of either humei or inornatus compared with the deep split between the two taxa.
Genetic differentiation and phylogenetic relationships of Bonelli's Warbler Phylloscopus bonelli and Green Warbler P. nitidus
TLDR
MtDNA sequence data promise to be very useful in quantifying the genetic differentiation and phylogenetic relationships among closely related species, especially in morphologically poorly differentiated genera like Phylloscopus.
Greenish Warbler, 'Two-barred Greenish Warbler', and the speciation process
TLDR
This Taxonomic Research Update draws birdwatchers' attention to the work of Irwin et at (2001) on Greenish Warblers Phylloscopus trochiloides, which shows that two subspecies do not interbreed in the region where their ranges overlap because they do not recognise each other's songs.
CIRCULAR OVERLAPS: RARE DEMONSTRATIONS OF SPECIATION
TLDR
One of the most widely known of the proposed examples of ring species is the series of taxa in the Herring Gull and Lesser Black-backed Gull group (Crochet et al. 2002).
Speciation in a ring
TLDR
This work reconstructs the pathway to speciation between two reproductively isolated forms of greenish warbler and shows how gradual divergence in a trait involved in mate choice leads to theformation of new species.
Ring species as bridges between microevolution and speciation.
TLDR
Analysis of proposed cases of ring species suggests that differences could have arisen even with gene flow, and that parallel rather than divergent ecological changes have led to divergence in sexually selected traits and subsequent speciation.

TLDR
It is suggested that parallel south-to-north ecological gradients have caused a greater intensity ofSexual selection on song in northern populations and that the stochastic effects of sexual selection have led to divergence in song structure.
