The western subalpine warbler (Curruca iberiae) is a small typical warbler which breeds in the southernmost areas of Europe and north-western Africa.

Contents

Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back and head, brick-red underparts, and white malar streaks ("moustaches"). The female is mainly brown above, with a greyer head, and whitish below with a pink flush. The subalpine warbler's song is fast and rattling, and is similar to the lesser whitethroat.

This bird seems to be related to the Sardinian warblerMenetries' warbler superspecies. They all have white malar areas, the heads being dark above in adult males, and naked eye-rings. These three species are related to a superspecies consisting of Rüppell's warbler and the Cyprus warbler, which also share the white malar area with blackish above (Shirihai et al. 2001, [1] Jønsson & Fjeldså 2006 [2] ). The subalpine warbler is divided into two distinct subspecies groups, which may possibly be sufficiently diverged to qualify as two separate species (Shirihai et al. 2001). [1] The two groups have differing male plumages, distinctive calls, and are allopatric; further study is needed. In May 2020, the IOC world bird list the western and eastern subalpine warblers were split into two distinct species. [3]

This is a bird of dry open country, often on hill slopes, with bushes for nesting. The nest is built in low shrub or gorse, and 3–5 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries.

Habitat and ecology

This species prefers tall and dense heterogeneous maquis with sparse tree cover in dry Mediterranean areas, particularly maquis of holm oak (Quercus ilex) and those dominated by strawberry tree (Arbutus) and tree-heath (Erica). It is also frequently found in young cork oak (Quercus suber) forest and in dense but treeless bushy areas. It uses bushy formations dominated by brambles (Rubus fruticosus) along sunny ravines and valley bottoms and prefers the intermediate stages of post-wildfire succession. Breeding occurs from late March to late June and the species is monogamous. The male constructs several ‘cock nests’ but both sexes build the breeding nest which is a deep, robust cup of grasses, thin roots and leaves and lined with finer grasses, rootlets and hair. It is placed in low scrub, bush or a small tree, c. 30–130 cm above the ground. Clutches are three to five eggs. The diet is mostly small insects and their larvae but outside of the breeding season berries and fruits are also taken. The species is a long-distance migrant, wintering in sub-Saharan Africa (Aymí et al. 2015). [4]

Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller number of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.

<span class="mw-page-title-main">Sardinian warbler</span> Species of bird

The Sardinian warbler is a common and widespread typical warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds.

The adult male has grey-brown upperparts and is dull reddish-brown below except for the centre of the belly which has a dirty white patch. It has light speckles on the throat and a red eye-ring. The sexes are similar but the adult female is usually less grey above and paler below.

<span class="mw-page-title-main">Asian desert warbler</span> Species of bird

The Asian desert warbler is a typical warbler which breeds in the deserts of central and western Asia and the extreme east of Europe, and migrating to similar habitats in southwestern Asia and the far northeast of Africa in winter. Until recently it was considered conspecific with the African desert warbler, but is now given specific status. The two are still each other's closest living relatives, and their relationships to other typical warblers are not clear. They may be fairly close to the common whitethroat; particularly, female whitethroats look much like a richly coloured Asian desert warbler. But it seems that all these three taxa are fairly basal members of the genus.
