Hobby (Falco subbuteo)
Whiskered Tern (Chlidonias hybrida)
Small and very elegant falcon, with white throat and rufous thighs (adults). Long, narrow wings and medium long tail. Dark grey above and heavily streaked below. Head dark, with marked facial pattern resembling Peregrine. Tail often looks slightly wedge-shaped. Impressive speed of flight, with acrobatic skills when hunting. Often hunts flying birds high in the air. Slower flight action when hunting insects. Will glide, but seldom hovers (as opposed to Red-footed Falcon). Perched birds shows wing-tips reaching end of tail.
Sound:Varied, but not very vocal. Calls when courting and at breeding ground. Most common sound a high-pitched "tew-tew-tew". Similar to Wryneck, but less pleading. Also a sneezing "ktcho".

Largest 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".
