We studied small widely distributed Eurasian passerine species, the Scarlet Rosefinch (Carpodacus erythrinus) whose winter grounds are supposed to be located in India and Pakistan. Using mitochondrial DNA sequences and applying an isolation with migration model we found that despite extensive gene flow among (even very distant) populations, localities at the southwestern end of the species range (Caucasus, Turkey, and Bulgaria) are relatively genetically isolated from the rest of the species breeding area. Our estimates suggest dramatic reduction of the species effective population size preceding the separation of south-western localities whose timing estimates roughly coincide with the onset of the world's most recent glacial period. The fragmentation of the breeding range appears to have caused separation also of the wintering grounds and changes in the migration pattern. Unexpectedly, while the presence of haemosporidian blood parasites detected using DNA barcoding supports the separation of the southwestern localities, microsatellite loci and nuclear gene intron sequences have not provided any significant signal of population structure.
