| − | The '''gizzard''' is the mechanical “stomach” of a [[bird]]. It is located just after the true or glandular stomach in the gastrointestinal system. Since [[poultry]] have no teeth and swallow feed whole, this muscular organ, sometimes called “hen’s teeth,” mechanically grinds and mixes the [[bird]]’s feed.<ref>[http://www.fsis.usda.gov/Help/A-Z_Index/index.asp USDA Index]</ref>
