Abstract

The Lesser Whitethroat Sylvia curruca complex continues to provide challenges for ornithologists and taxonomists. One of the remaining outstanding questions concerns the taxonomic identity of the different breeding populations in Iran and in particular zagrossiensis, which inhabits the Zagros mountains. We here used the three mitochondrial genes cyt b, COI and ND2, to evaluate samples of the Lesser Whitethroat complex from Iran. Our data include predominantly samples from the breeding season, and we find evidence of three taxa from Iran, of which two are certainly breeding; althaea from Kopet Dagh in NE Iran and the Kerman mountains, east of the Zagros mountains, SE Iran; and curruca from central Zagros mountains and northwestern Iran. Three samples of halimodendri from the south of Iran were migrating or wintering birds. The taxonomically contentious population from the Zagros mountains is here identified as belonging to the curruca clade, and evidence to recognize zagrossiensis based on molecular data is deemed insufficient.
