Moustached Warbler (Acrocephalus melanopogon)
Yellow Wagtail (Motacilla flava)
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.

Highly variable with many subspecies in different regions. Upperparts mainly grey and greenish, underparts yellow. Tail quite short compared to other wagtails, and the whole bird in profile is not unlike a pipit. Smallest wagtail in the region. Some birds are very pale below, head markings are very variable, depending on subspecies. Hybrids are not uncommon. Differs from Grey Wagtail in dark legs, only pale yellow vent and narrow wing-bars. Juvenile White Wagtails and Yellow Wagtails can be confused, but White Wagtail is greyer, with big grey breast patch (Yellow Wagtail may show narrow breast band). Closest congener is Citrine Wagtail, which lacks dark lore, has broad wing-bars and grey back.
Sound:Contact call characteristic and widely used; a sharp, drawn out "pseeeoo" with an accented ending falling in pitch. Song primitive and less striking. A variable phrase with two or three notes resembling the contact call in timbre. Beware differences in calls and songs between different subspecies.
