Closely related to Subalpine Warbler. Paler rufous below compared to the western species of Subalpine Warbler and lacks contrast between the rusty throat and whitish belly like the eastern subspecies of Subalpine Warbler. Breeds in Mediterranean scrub. In winter found in semi-arid acacia savanna. Call a diagnostic dry “trrrrr,” reminiscent of Spectacled Warbler.
