Résumé :	A first-winter male Naumann's Thrush Turdus naumanni discovered at Woodford Green, Essex, on 3rd February 1990 remained until 9th March 1990, although it transpired that the bird had been present since 19th January. During its stay, it frequented gardens and an adjacent playing field, where it was watched by several hundred observers. Until recently, Naumann's Thrush and the closely related Dusky Thrush T. eunomus were treated as races of a single species; Dusky Thrush had already occurred in Britain but this was the first occurrence of Naumann's Thrush. Following a review of diagnosable plumage differences, and after considering the relatively infrequent occurrence of hybrids, BOURC concluded that Naumann's and Dusky Thrushes represent monotypic species, and both were accepted into Category A of the British List. This paper describes this record, and also discusses the distribution of Naumann's and Dusky Thrushes and the occurrence of hybrids.
