Résumé :	The recent occurrence in the breeding season of phenotypical Red-spotted Bluethroats in German, Dutch and Polish parts of the breeding range of White-spotted Bluethroat has resulted in several publications. As those birds in several cases were recorded as breeders, it was dicussed whether they were hybrids, wore alien plumages or showed extreme aberrations from the breeding plumages of white-spotted (L. s. cyanecula) or red-spotted subspecies (L. s. svecica, L. s. occidentalis = volgae). This review of the current knowledge about mixed breeding also includes information about a mixed population from the Czech part of the Giant Mountains (Krkonose), where genotypical white-spotted birds are involved in breeding in a population of Red-spotted Bluethroat in (sub)alpine habitats since at least 1992.
