Pied Flycatcher (Ficedula hypoleuca)
Whiskered Tern (Chlidonias hybrida)
Male with shiny black upperparts and pure white underparts. Female grey-brown with pale underparts. Both sexes with broad white edges to tertials and greater coverts, forming a broad white patch (largest in males). Fairly compact body compared to Spotted Flycatcher, with shorter tail and bill. Easily confused with Collared- and Semicollared Flycatcher where these occur. Both sexes differs from Semicollared in no white edges to end of tail and less white at base. Distinguished from Collared in white patch beneath alula being narrow and not reaching edge of wing (both sexes), white base of tail (black in Collared males) and no collar (males).
Sound:Alarm call a sharp, energetic "wit", often in combination with a short "tic"; "whit-tic". Song a pleasant, tuneful, simple but varied phrase. Typically starts with disyllabic notes being repeated 3-5 times, diminishing in pitch and intensity like an echo of the first two syllables. Occasionally throws in a quick diagnostic ascending scale excercise. Clear notes and well defined pauses between phrases.

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".
