Non-traditional foods other than turkey are sometimes served as the main dish for a Thanksgiving dinner. Ham is often served alongside turkey in many non-traditional households. Goose and duck, foods which were traditional European centerpieces of Christmas dinners before being displaced, are now sometimes served in place of the Thanksgiving turkey. Sometimes, fowl native to the region where the meal is taking place is used; for example, an article in Texas Monthly magazine suggested quail as the main dish for a Texan Thanksgiving feast. John Madden, who appeared on television for the NFL Thanksgiving Day game from 1981 to 2001, frequently advocated his fondness for the turducken, deboned turkey, duck and chicken nested inside each other then cooked. In a few areas of the West Coast of the United States, Dungeness crab is common as an alternate main dish, as crab season starts in early November. Similarly, Thanksgiving falls within deer hunting season in the Northeastern United States, which encourages the use of venison as a centerpiece. Vegetarians or vegans may have a tofu, wheat gluten or lentil-based substitute; or stuffed squash. In Alaskan villages, whale meat is sometimes eaten. Irish immigrants have been known to have prime rib of beef as their centerpiece since beef in Ireland was once a rarity; families would save up money for this dish to signify newfound prosperity and hope. Many Italian-Americans will serve capon as the main course to the Thanksgiving meal.
