according to the dictionary app i have on my ipad (i'm not sure what the real source is), it's even more complicated and confusing than that, and it has to do with the guinea fowl (which, funny enough, in portuguese is known as "angola fowl"). this is from the etymology entry for the word "turkey":
Quote:
1540s, "guinea fowl" (Numida meleagris), imported from Madagascar via Turkey, by Near East traders known as turkey merchants. The larger North American bird (Meleagris gallopavo) was domesticated by the Aztecs, introduced to Spain by conquistadors (1523) and thence to wider Europe, by way of North Africa (then under Ottoman rule) and Turkey (Indian corn was originally turkey corn or turkey wheat in English for the same reason). The word turkey was first applied to it in English 1550s because it was identified with or treated as a species of the guinea fowl. The Turkish name for it is hindi, lit. "Indian," probably via Fr. dinde (contracted from poulet d'inde, lit. "chicken from India"), based on the common misconception that the New World was eastern Asia. The New World bird itself reputedly reached England by 1524 at the earliest estimate, though a date in the 1530s seems more likely. By 1575, turkey was becoming the usual main course at an English Christmas.
about the word "peru", apparently the misconception existed (that peru was where the bird came from), but it was based on the habit of using the name peru to refer to all the hispanic lands in the americas (just like in brazil it's common for people to refer to lebanese immigrants as -- guess what -- turks

)
That IS complitcated.
But interesting. Yes...it was the Aztecs of Mexico (not the Incas of Peru) who first introduced the Turkey to Europeans.
Interesting that the New World foul got from Spain to the rest of western Europe the long way through Muslim North Africa and then through Turkey- rather than going directly up the Atlantic seaboard of Europe to France and England. Notice that the turkey eating at Christmas custom became established in England by the late 1500's. So when the Pilgrims had their famous feast in post 1620 in the colonies - turkies were already old hat for the English colonists. You tend to assume that the local Massachusettes Indians introduced them to turkies.
How did guinea pigs (which really do come from the Andes Mountains region around Peru) come to be called "guinea pigs"? Not only are they not pigs, but "Guinea" is on the west coast of Africa!
