Bluethroat thrush bird is similar in shape to the Robin, but slimmer and longer legged. On the ground it hops and runs well, with the tail cocked and a noticeably erect carriage. The bluethroat thrush bird (male) is unmistakable, with a bright blue throat and chest, ringed on the lower edge with a black band, a narrow whitish band and a broad rusty-reddish band above the belly. Most populations have a large red throat spot, although this spot is white in the race cyanecula or 'White-spotted' Bluethroat, which breeds from eastern France to Russia. It has a long broad whitish supercilium, a whitish belly and cold brown upper-parts. The tail is diagnostic, being blackish-brown with a chestnut basal half which shows as side panels when fanned or as the bird flies low over the ground. Females and immatures lack the full blue throat to varying degrees, the least well-marked birds showing just a buffy white throat ringed by a greyish-brown gorget.
Bluethroat thrush bird is a scarce migrant in Britain, the breeding range stretching in separated blocks from Spain and France to eastern Europe and Scandinavia. It favours scrub and bushy thickets, wooded clearings, open boggy willow and birch forest, thick stands of herbage, fens, reedbeds and riverine woodland, nearly always with a swampy component. It winters in north-east Africa, India and south-east Asia.
Bluethroat thrush bird has various little chat-like calls, a throaty swallowed "thuck", a churring "trrrk", a high-pitched "tzii", and an anxious descending "zree'ze'ze'ze'ze", heard sometimes on the wintering grounds. The song of bluethroat thrush bird has similarities with the Nightingale's, but is busier and more highly pitched, with squeaky and buzzy elements, throat clicks and squelching sounds. It is incredibly varied, including much mimicry of other species, with particular groups of notes usually repeated twice, and is often sung continuously rather than in set phrases, such as "suchee sichoo chk'chk'chk, eeh-di'didi'choo, eeh'di'didi'choo, kik'wheeee, kik'wheeee, tractractrac, fzzzrrrt fzzzrrrt, it'titi'titi'ti, trrrrtrrrrr..."etc.
