Why Yokohama names differ between countries

The Rare Poultry Society explains that European imports of several Japanese long-tailed types were associated with the port of Yokohama. German fanciers later restricted Yokohama to a particular red-saddled form and used Phoenix for a white-lobed, single-combed type. British fanciers used Yokohama more broadly. Consequently, a British label may cover birds that another country's system separates. A teaching collection must specify that context instead of silently combining national identities.
