Grasshopper Warbler (Locustella naevia)
Gannet (Morus bassanus)
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".

CCWhite with black wing tips and yellow-buff at back of head. Juveniles brown with small pale speckles, white u-shaped rump patch and pale underparts. Fully coloured only after 5 years, and patchy, intermediate plumages often seen. Unmistakable bird at close range or with favorable light, but can be confused with shearwaters at a distance and/or in strong wind. Differs from those by long tail and much longer neck and head. Alternates between powerful, even and shallow wing-beats and glides. Flight becomes more shearwater-like in strong winds.
Sound:Heard mostly at breeding ground. Even, rhythmical series of harsh "harrr, harrr, harrr,".
