Subspecies

In their large continental Eurasian range, robins vary somewhat, but do not form discrete populations that might be considered subspecies. Robin subspecies are mainly distinguished by forming resident populations on islands and in mountainous areas. The robin found in the British Isles and much of western Europe, Erithacus rubecula melophilus, occurs as a vagrant in adjacent regions. E. r. witherbyi from northwest Africa, Corsica, and Sardinia closely resembles melophilus but has shorter wings. The northeasternmost birds, large and fairly washed-out in colour, are E. r. tataricus. In the southeast of its range, E. r. valens of the Crimean Peninsula, E. r. caucasicus of the Caucasus and northern Transcaucasia, and E. r. hyrcanus southeastwards into Iran are generally accepted as significantly distinct.

On Madeira and the Azores, the local population has been described as E. r. microrhynchos, and although not distinct in morphology, its isolation seems to suggest the subspecies is valid (but see below).
