Gizzard
From Free net encyclopedia
The gizzard is a very muscular stomach that is found in birds, earthworms, and other animals.
Often, animals that lack teeth will swallow stones to aid in digestion. "A bird swallows small bits of gravel that act as 'teeth' in the gizzard, digestively breaking down hard food such as seeds and thus helping digestion." (Solomon et. al, 2002) These stones are called gizzard stones and are usually smooth and round from the polishing action in the animal's stomach.
Dinosaurs are also known to have used gizzard stones. When found in association with fossils, they are called gastroliths.
The gizzards of poultry are a popular food in some places. Grilled chicken gizzards are sold as street food in China, stewed gizzards are eaten as a snack in Portugal, while pickled turkey gizzards are a traditional food in some parts of the Midwestern United States. In the Southern United States, the gizzard is typically served fried, sometimes eaten with hot or honey mustard sauce.
