Appearance:

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.

Appearance:

Very similar to Parrot Crossbill, but has thinner neck, smaller head, steeper forehead and slender bill. Upper mandible is less curved towards the tip than in Parrot Crossbill, and the lower is straight, with no bulge. The tip of the lower mandible protrudes from behind the upper (tips of mandibles visibly crossing). The chest is less deep, and birds are not so front heavy. Large individuals may be difficult to identify because of overlapping characters with Parrot Crossbill. Plumage similar to Parrot, with dark wings and tail. Males with rufous red head and body, females green. Juveniles greyish green with streaking. Posture more erect than Parrot Crossbill, especially when foraging on ground.

Sound:

Contact call similar to Parroy Crossbill's "tupp", but is on average higher and less powerful, with a "cut-off" ending. In sum: Parrot Crossbill; hard attack, soft ending, Crossbill: softer attack, cut-off ending. Beware regional variations and overlap in pitch of calls with Parrot. The song consist of improvised, resonant twittering, and series of contact calls with no apparent phrases. It is generally faster, with less marked pauses than in Parrot Crossbill, and the phrasing seems more random.
