Abstract:Summary. Ample material of breeding birds has shown that S. v. vulgaris and S. v. tauricus intergrade, through hybridization, over an area of considerable extent and that S. v. balcanicus is a hybrid between them. This result, combined with the conclusions reached by Stegmann (1935), considerably simplifies the problem of geographical variation in Sturnus vulgaris. Only six principal subdivisions can be maintained: (1) vulgaris (and its insular offshoots), (2) menzbieri, (3) caucanicus+nobilior, (4) taics+porphyronotus, (5) humii, (6) minor. Neighbouring races are connected by hybrid populations, some of which inhabit a large area. Among the names which have been bestowed on hybrids are S. vulgaris balcanicus = vulgaris×tauricus, S. vulgaris purpurascens=taricus×caucasicus, S. vulgaris poltaratzkyi = porphyronotus×menzbieri. S. vulgaris dresseri = porphyronotus×menzbieri, S. vulgaris dzungaricus=porphyronotus×menzbieri. Random combination of characteristics sometimes results in hybrids of different origin being almost indistinguishable (e. g.×dresseri and ×purpurascens, according to Sushkin, 1933). Within the area occupied by “pure” races there is rather slight individual variation in quality of iridescent colour. In S. v. vulgaris, for instance, two extremes of individual variation can be distinguished which are not evenly distributed over the whole range of the subspecies.
