<strong>Specie</strong> ad anello<br />
Il luì verdastro (Phylloscopus trochiloides)<br />
Map of Asia showing the six subspecies of the greenish warbler described by Ticehurst in 1938. The crosshatched blue<br />
and red area in central Siberia shows the contact zone between viridanus and plumbeitarsus, which do not interbreed.<br />
Colors grade together where Ticehurst described gradual morphological change. The gap in northern China is most<br />
likely the result of habitat destruction.
