The western subalpine warbler is a small Sylviidae warbler which breeds in the southernmost areas of Europe and north-western Africa.
Region
Western Mediterranean Basin
Typical Environment
Breeds mainly in the Iberian Peninsula, southernmost parts of Europe, and north-western Africa in dry, sunny shrublands. Prefers maquis and garrigue dominated by cistus, rosemary, juniper, and other low shrubs, often on rocky slopes and coastal scrub. Uses woodland edges and open mosaic habitats with scattered bushes for nesting and foraging. In winter it migrates to the Sahel zone of West Africa, frequenting thorn scrub and savanna with dense understory.

The western subalpine warbler is part of a recently split complex, now separated from the eastern subalpine warbler and Moltoni’s warbler. Males show a warm rufous throat and breast, grey head, and a neat white moustachial stripe, while females are plainer and browner. It is a skulking species of Mediterranean scrub, often revealed by its scolding calls and tail-flicking. Identification can be tricky; voice, subtle plumage tones, and range are helpful clues.
Temperament
shy and skulking
Flight Pattern
short rapid wingbeats with low, darting flights
Social Behavior
Typically seen singly or in pairs during the breeding season, holding small territories in dense scrub. The cup-shaped nest is built low in bushes, and both parents feed the chicks. Outside the breeding season it may join loose mixed-species groups in suitable scrub.
Migratory Pattern
Seasonal migrant
Song Description
A lively, scratchy warble with rattling trills and short, hurried phrases delivered from a shrub top or within cover. Calls include a sharp tack or tchet and a dry scold when alarmed.
