Etymology

The word "gizzard" comes from the Middle English giserdd, which derives from a similar word in Old French, and earlier from the Vulgar Latin "*gicerium", which follows from the Latin word "gigeria", meaning cooked entrails of poultry. The Latin word "gigeria" probably is derived from the Persian word for liver, which is "jiger".

Structure

Birds swallow food and store it in their crop if necessary. Then the food passes into their glandular stomach, also called the proventriculus, which is also sometimes referred to as the true stomach. This is the secretory part of the stomach. Then the food passes into the ventriculus (also known as the muscular stomach or gizzard). The gizzard can grind the food with stones that have been swallowed and pass it back to the true stomach and vice versa. Bird gizzards are lined with a tough layer made of the protein keratin, to protect the muscles in the gizzard.

Gizzard stones

Some animals that lack teeth will swallow stones or grit to aid in digestion. All birds have gizzards, but not all will swallow stones or grit. The birds that do, employ the following method of 'mastication':
"A bird swallows small bits of gravel that act as 'teeth' in the gizzard, breaking down hard food such as seeds and thus helping digestion." (Solomon et. al, 2002).
These stones are called gizzard stones or gastroliths and are usually smooth and round from the polishing action in the animal's stomach. When too smooth to do their required work, they may be passed or regurgitated.

Animals with gizzards

Emus, turkeys and chickens, like all birds, have gizzards. Mullets (Mugilidae) found in estuarine waters worldwide, and the gizzard shad, or mud shad, found in freshwater lakes and streams from New York to Mexico, have gizzards. The Gillaroo (Salmo stomachius), has a gizzard. It is a species of trout found in Lough Melvin in County Fermanagh, Northern Ireland. It is a distinct species, characterized by a rich coloration. Its gizzard is used to aid the digestion of water snails, the main item of its diet.
Crocodiles also have gizzards.

Dinosaurs with gizzards

Dinosaurs believed to have had gizzards based on the discovery of gizzard stones recovered near fossils:

Eating gizzards

The gizzards of poultry are a popular food throughout the world. Grilled chicken gizzards are sold as street food in South Korea, China, Taiwan, Japan, Philippines, Haiti, and throughout Southeast Asia. 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 Hungary it is made with paprika. In the Southern United States, the gizzard is typically served fried, sometimes eaten with hot or honey mustard, or added to crawfish boil along with crawfish sauce. In Chicago, gizzard is battered, deep fried and served with fries and sauce. Gizzard and mashed potato is a popular food in many European countries. In France, especially the Dordogne region, gizzards are eaten in the traditional Perigordian Salad, along with walnuts, croutons and lettuce.
In Yiddish, gizzards are referred to as "pipik'lach", literally meaning navels. The gizzards of kosher species of birds have a green or yellowish membrane lining the inside, which must be peeled off before cooking, as it lends a very bitter taste to the food. In traditional Eastern European Jewish cuisine, the gizzards, necks, and feet of chickens were often cooked together, although not the liver, which per Kosher law must be broiled.
In Cameroon and Nigeria, the gizzard of a cooked chicken is traditionally set aside for the oldest or most respected male at the table.
Giblets consist of the heart, liver and gizzard of a bird, and are often eaten themselves or used as the basis for a soup or stock.

Generic meaning

Gizzards can also refer to the general guts, innards or entrails of other animals, as in the phrase 'hand over the treasure or I'll slit yer gizzards me hearty' that may be uttered by a storybook pirate.

Trivia

A regular character on the The Kenny Everett Television Show was named Gizzard Puke.
