Black Redstart (Phoenicurus ochruros)
Whiskered Tern (Chlidonias hybrida)
Male: Charcoal to black plumage, with rufous red tail, pale belly and pale wing-panel (south-eastern subspecies with rufous belly and no wing-panel). Female: Grey brown overall, except rufous tail. Lacks the orange tinge to breast and belly of female Common Redstart. Juveniles resembles the adult female, and lacks the buff speckles of congeners. May jump around on the ground like CR, but are more prone to run. Also shows a more erect posture.
Sound:Song consists of three parts and is distinct if heard well. It opens with some clear notes that may form a trill, which are then followed by a pause. Next part is rather unique, and sounds as if shaking a handful of gravel. The phrase then usually closes with a couple of trills. The "gravel-part" does not carry as far as the rest of the song. Alarm call is a chat-like alternation between short, high-pitched "wit" sounds, and series of hard and dry "teck".

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".
