Summary. The diagnostic criteria, ranges, hybrid zones, and migrations of the three indigenous British races of Turdus ericetorum are defined. The migratory dispersal of T. e. catherinœ is traced, and its identity as the innominate “small, dark migrant Song‐thrush” of workers is established. An explanation of the distributions of T. ericetorum races in the British Isles is advanced. T. e. ericetorum and T. e. hebridensis are ascertained to be moderately migratory, T. e. catherinœ strongly so. The findings on early records of T. e. hebridensis on passage evidence confusion between that form and T. e. catherinœ. Irish, Stornoway (Lewis, Outer Hebrides), and Orkney and Shetland breeding populations require further racial study.
