Geographical variation limited, mostly clinal, and mainly involving plumage color which may be affected by wear in the harsh arid climate. Following Gloger's rule birds in more humid areas average darker and more tinged with olive-brown on their upperparts and are more warmly colored on their underparts. Populations in more arid areas average grayer and paler, with less brown, on their upperparts and are paler on their underparts. Island populations in the Aegean Sea average smaller than those from continental populations.
