| Résumé : | Blyth's Reed Warbler Acrocephalus dumetorum remains one of the most difficult identification challenges facing field birders in Britain. This paper describes a case where identification was still not proven, despite the bird being trapped and measured. This example raises a number of important general points regarding the process by which rarities are assessed, in particular the care with which photographic evidence and biometric measurements must be interpreted. |
