Curruca iberiae
The Western Subalpine Warbler (Curruca iberiae) is a captivating passerine, a recent addition to the ornithological species list, having been recognized as distinct from the former 'Subalpine Warbler' complex in the early 2000s. Males are particularly striking, measuring 12-13 cm in length, with a wingspan of 15-18 cm and weighing 7-12 grams. They boast a distinct slate-grey head, a vibrant white moustachial stripe contrasting with a white throat, and rich rufous flanks extending to a white b...
This warbler thrives in dry, open Mediterranean scrubland, garrigue, and maquis, often with scattered evergreen oaks or pines. It typically breeds from sea level up to approximately 1500-2000 meters in elevation.
Their diet consists primarily of insects and their larvae, especially caterpillars and small beetles, supplemented by small berries and fruits in late summer and autumn.
The Western Subalpine Warbler is a diurnal and highly active species, known for its restless, darting movements as it flits through dense scrub. It primarily forages by gleaning insects from foliage and branches, often making short, agile flights to snatch prey. Males are fiercely territorial dur...
The Western Subalpine Warbler's breeding range is primarily confined to the Iberian Peninsula, encompassing most of Spain and Portugal, and extending into northwestern Africa across Morocco, Algeria, and Tunisia. After breeding, these warblers undertake a significant trans-Saharan migration to th...
