Marsh Warbler (Acrocephalus palustris)
Merlin (Falco columbarius)
Plain and characterless plumage, but conspicuous song. Larger than Sedge Warbler, with larger wings, broader tail and tail-base. Very similar to Reed Warbler, and very hard to distinguish by plumage alone. Rump of Marsh warbler shows less contrast to back, and flanks have a yellowish tinge. Bill slightly shorter and less pointed. Differs from Blyth's Reed Warbler by longer primary projection, yellowish lower mandible and paler legs. Juveniles especially hard to identify because of even fainter plumage field marks. Less common in reed beds than Reed Warblers, and more attached to bushes with lush undergrowth.
Sound:Song extremely varied and full of mimicry of both European and African species. Up to 75 species imitated by the same bird. Phrases often repeated 2-4 times, and different phrases may overlap. Nevertheless, clearly defined phrases with marked pauses. Sometimes more flowing streams of notes, but less so than Icterine Warbler. Most similar to Icterine and Blyth's Reed Warbler. Softer timbre than Icterine, and not so loud. More defined pauses and staccato tempo, and lacks Icterine Warbler's nasal high-pitched calls. Differs from Blyth's Reed Warbler in fewer repetitions of each phrase, and lack of said species' whistling, arpeggio-like calls. Typical sequence is a hoarse, drawn "ti-chaaa". Alarm call a short "chepp" with clipped ending.

CCSounds:Recorded by Edmunds Racinskis
Smallest falcon. Male with slate grey upperparts, and pinkish buff, speckled underparts . Female dark brown above and heavily speckled below. Due to the extensive markings, the underparts give a darker impression than in Kestrel. Tail of female with dark broad bands, tail of male with broad black terminal band. Diffuse facial markings. Short wings. Silhouette similar to Peregrine, but the much faster wing beats are diagnostic. Acrobatic flight with sharp twist and turns when chasing prey. Alternating glides and bursts of wing-beats gives undulating flight.
Sound:Series of harsh "kwik-wik wik". Coarseness similar to Peregrine, but pace much quicker. Female call harsher than male. Lacking the clearer tones and attack of Kestrel.
