Why do turkey and Turkey share the same name?
Once imported, Europeans came to call the guinea fowl the turkey-cock or turkey-hen, because the bird came from the Turks. When settlers in the New World began to send similar-looking fowl back to Europe, they, out of familiarity, called them turkeys.
Where are turkeys from?
Domestic turkeys come from the Wild Turkey (Meleagris gallopavo), a species that is native only to the Americas. In the 1500s, Spanish traders brought some that had been domesticated by indigenous Americans to Europe and Asia.
