Moustached Warbler (Acrocephalus melanopogon)
Subalpine Warbler (Curruca cantillans)
Small and restless species easily confused with Sedge Warbler, Acrocephalus schoenobaenus, but showing both plumage and structural differences. Plumage differs from A. schoenobaenus in; broad, white supercilium ending without narrowing, dark crown (usually appears black), pure white throat, grey ear-coverts, dark legs and warm-rufous flanks, rump and neck. Facial markings recalling firecrest. Very short primary projection and longer, more evenly rounded tail recalling Wren when raised. Bill thinner than A. schoenobaenus. Skulky behaviour, forages low in vegetation, on ground or near water surface. Some variation in both size and plumage between western and eastern subspecies.
Sound:Contact call a dry "trrrt", similar to corresponding call of Sedge Warbler. Song most resembling that of Reed Warbler (A, scirpaceus), but often includes diagnostic (unique among congeners), pure-sounding note sequence resembling crescendo of Common Nightingale (L. megarhynchos), before launching into typical Acrocephalus sounding song. This latter type can be sustained for some time without the diagnostic sequence and is more difficult to distinguish from A. scirpaceus. Note faster tempo and more variation.

Medium small Sylvia with short tail, slender body and steep forehead. Bill slim,fairly short and pointed. Male with rufous breast and conspicuous, broad, white moustache stripes. Upperparts lead grey. Female with slightly more brownish upperparts and buff white below. Immature birds has greyish brown upperparts, and are prone to confusion with Spectacled Warbler due to broad, brown fringes of tertials. The colour is however less rufous, and the dark centre ends in a rounded, not pointed tip. Pale legs in all sexes and ages, but some variation. Eye-ring colour variable, but generally red in male and very pale in female and immature (rules out other Sylvia except Tristram and Sardinian). Colour of upperparts more uniform than in confusion species in both male and female. May cock tail, but does not keep it raised like Dartford Warbler. Taxonomy much discussed. Western Italian population now accepted as a separate species (Moltoni's Warbler, S. subalpina), while S. c. inornata has species status in Svensson, but not in Clements (2018) .
Sound:Alarm call a short, hard "tuk", but softer and fainter than Blackcap and Sardinian W. Song a rapid, vivid stream of squeaks and clearer notes, with timbre similar to Whitethroat. May be confused with Sardinian W., but lacks that species interwoven hard and rolling contact call.
