Song Thrush (Turdus philomelos)
Whiskered Tern (Chlidonias hybrida)
A medium sized thrush with evenly brown to olive-brown upperparts. Underparts boldly covered with arrow-shaped spots. Chest with buff tones. Faint face patterns and buff underwing coverts distinguishes it from all other thrushes in the region. Lacks the white cheek-spot of Mistle Thrush, and the colour of the back of the head is not paler than the back. Sexes alike. Juveniles with buff-spotted upperparts. Quite short-tailed and compact, with rounded wings. Jerky, and not very undulated, flight pattern.
Sound:Very melodious, varied and a master imitator. Still easily distinguished by its tendency to repeat introductory motives two or more times, and its many high pitched themes. Each phrase is loud and penetrating and the tempo deliberate. Most heard (but easily overlooked) contact call is a dry and very short "zip", sometimes given as a two syllable call "zip-ip".

CCLargest marsh tern. Liable to confusion with Sterna terns due to black cap, in addition to other marsh terns. All marsh terns (Chlidonias) differs from Sterna by lack of tail streamers, short tail with shallow fork, shorter wings and stiffer flight. Marsh terns don't plunge-dive for food but picks from surface (though Whiskered Tern may belly-plunge), mostly in fresh water. Adult Whiskered Tern easily told from other marsh terns by distinct black cap contrasting to white cheeks and throat. Underwing pale with diffuse dark trailing edge. Belly distinctly darker than Common- and Arctic Tern, but beware of variation in both species. Bill dark blood red. Adult winter: Very pale with no distinct markings except for ill-defined black mask stretching from eye to eye across nape. Forehead white and with crown white speckles. Bill black. Immature: Yellowish brown saddle with coarse dark pattern, though these are moulted in early autumn. Usually lacks dark carpal bar and cap ill-defined. Whiskered Tern generally stockier built than other marsh terns. Both immatures and adult winter show grey rump (different from Common, Arctic and White-Winged), and bill is dagger-shaped (most apparent in males).
Sound:Contact call freely used and fairly distinct: An extremely hoarse, and rasping "krreek" in various moods. Timbre comparable to Corncrake. Sometimes uttered in stuttering series "kr-kr-kr-kr-kr".
