On Thanksgiving Day, most of us will sit down to enjoy a turkey dinner. The bird also shows up on the table at Christmas. How did we start with the tradition of savoring turkeys during the holidays?

They were fresh, cheap, and big enough to feed a group of people. Americans like having large poultry(家禽) for celebrations because they don’t need to pay a lot for the birds. Cows were more useful alive than dead, and beef wasn’t widely offered until the late 19th century. Chicken was more highly regarded than it is today. Venison(鹿肉) would have been another choice, especially during the 17th and 18th centuries. Eating turkey was also a British holiday custom people brought to the New World.

Among the big birds, turkey is the most suitable for Thanksgiving. Turkeys were born in the spring. They spend about seven months eating insects on the farm. By Thanksgiving, they have grown to about 10 pounds. Turkeys are cheaper than geese, which are more difficult to raise, and cheaper by the pound than chickens. Cost is an important factor for holiday shoppers, because people will not prepare just one meal. Thanksgiving Day is the time to bake meal and other types of pies. The foods can last through the winter.
