Curruca iberiae
The Western Subalpine Warbler is a small warbler of dry Mediterranean scrub in Iberia, southern France, north-western Italy and north-west Africa, wintering in sub-Saharan Africa. Males are grey above with brick-red underparts and crisp white moustaches, while females are browner and paler below. Its song is a fast, rattling chatter. It was split from the Eastern Subalpine Warbler in 2020.

About the habitat
Dry, open Mediterranean country with tall, dense maquis, holm oak and strawberry trees, young cork oak stands, bramble thickets in sunny ravines and scrub regenerating after fires.
