Spanish sparrow
Two subspecies of Spanish sparrow are usually recognised, the western nominate subspecies "hispaniolensis", and the eastern "transcaspicus", described by Austrian ornithologist Viktor von Tschusi zu Schmidhoffen in 1902 from Ýolöten, Turkmenistan. Birds in Anatolia and Cyprus are usually considered to belong to "P. h. transcaspicus", but birds as far east as Ceylanpınar have been noted as intermediates and the difference between the two subspecies may actually be clinal.
