Citrine Wagtail (Motacilla citreola)
Grasshopper Warbler (Locustella naevia)
Adult male easily recognized with all yellow head with dark edges and grey back. Prominent white wing-bars and all dark bill, lacking the pale base of Yellow Wagtail. Females and adult winter lacks the dark lore-stripe of Yellow Wagtail, and the flanks are grey. The same applies to the juveniles. These also give a very grey impression, almost resembling a Pied Wagtail without the dark breast-pattern. Juvenile Yellow Wagtails have a less grey and more olive tone to their backs. The dark facial markings/earcoverts of females/winter/juveniles birds are usually framed by the continuation of the strong supercilium. Some Yellow Wagtails are very similar to Citrine, and call and tail length should be considered as well (tail longer in Citrine).
Sound:Contact call resembles Yellow Wagtail, but is harsher with a more buzzing quality, and of shorter duration. The pitch is more constant, lacking the rise and fall of Yellow Wagtail. The song is a loose repetition of phrases, comprised of disyllabic or monosyllabic contact calls.

Anonymously brown and dark brown warbler. Slender bill, short rounded wings and broad waist and tail. Base colour varies from olive-brown to yellowish buff. Streaking also varies from diffuse to marked, and is most prominent on sides of throat and upper chest. juveniles are more streaked than adults. Rufous/olive fringes to tertials are broader on outer side (as opposed to Pallas' Grasshopper Warbler). Secretive bird. Generally discovered by song.
Sound:Song insect-like and high-pitched. A monotonous stream of even clicks similar to a running fishing line. Maintained for seemingly endless periods, and often hard to locate. Song most similar to Savi's Warbler but is slower (each click more separated), and higher pitched with a metallic, ringing quality. Short sequences of song also functions as contact call. Also a Robin-like "tick".
