Nomenclature
"Ouzel" (or "ousel") is an old name for Common Blackbird from Old English osle. "Ouzel" may also be applied to a group of superficially similar but unrelated birds, the dippers, the European representative of which is sometimes known as the Water Ouzel.
As with the English name, the scientific name also refers to the male's obvious white neck crescent, being derived from the Latin words turdus, "thrush", and torque, "torc" (neck ring).
