Moustached Warbler (Acrocephalus melanopogon)
Blackbird (Turdus merula)
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.

Male shiny black with bright yellow bill and yellow eye-ring. Female dark brown above. Throat and chest in slightly paler tones with diffuse dark spots. Juveniles similar to females, but with fine buff streaking all over. More long-tailed than Redwing and Song Thrush. Flight action with alternating bursts of wing-beats and with little undulation (see Fieldfare).
Sound:One of the most appreciated song birds. Very melodious and resonant, with long mellow notes and a large register. Less high pitched sounds than Song Thrush, and seldom repeats a phrase. Timbre fuller than both Song Thrush and Mistle Thrush. Well defined pauses between phrases, giving the song a relaxed pace. Large repertoire of calls. Most characteristic is a hysterical rattle often given when flushed. Sometimes preceded by a hard "tok tok", which then accelerates into a panicky arpeggio-like crescendo. Contact call a thin redwing-like "srrreee". Alarm calls: a sharp "tink, tink" or a very high pitch falling whistle.
