The U.S. Thanksgiving holiday is symbolized by its traditional food, a large bird we call a turkey. But turkey is certainly not from Turkey. In fact, its English name is based on one big mistake. We could say it is a case of mistaken identity.
There’s an African bird called the guinea fowl. This foreign bird came to Europe through Turkish lands. So, the English thought of the bird as a Turkish chicken. When Europeans came to North America, they saw a bird that looked like the guinea fowl, which at that time was called the Turkey cock and so gave it the same name.
