Phenotype
Anthropologists relate Udmurts to the Urals branch of the large European race which has some features of the Mongolian race. The Udmurt people are distinguished by a large number of red-haired people who (together with the Irish) are probably one of the most "gold-haired" ethnic groups in the world. Most of them are of the middle size, often have blue or gray eyes, high cheek-bones and wide face. The Udmurt people are not of an athletic build but they are very hardy. and there have been claims that they are the "most red-headed" people in the world. Additionally, the ancient Budini tribe, which is speculated to be an ancestor of the modern Udmurts, were described by Herodotus as being predominantly red-headed.
