Blackbird (Turdus merula)
Whiskered Tern (Chlidonias hybrida)
Male shiny black with bright yellow bill and yellow eye-ring. Female dark brown above. Throat and chest in slightly paler tones with diffuse dark spots. Juveniles similar to females, but with fine buff streaking all over. More long-tailed than Redwing and Song Thrush. Flight action with alternating bursts of wing-beats and with little undulation (see Fieldfare).
Sound:One of the most appreciated song birds. Very melodious and resonant, with long mellow notes and a large register. Less high pitched sounds than Song Thrush, and seldom repeats a phrase. Timbre fuller than both Song Thrush and Mistle Thrush. Well defined pauses between phrases, giving the song a relaxed pace. Large repertoire of calls. Most characteristic is a hysterical rattle often given when flushed. Sometimes preceded by a hard "tok tok", which then accelerates into a panicky arpeggio-like crescendo. Contact call a thin redwing-like "srrreee". Alarm calls: a sharp "tink, tink" or a very high pitch falling whistle.

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".
