A gizzard is the muscular part of a bird’s stomach in which food it eats is ground up.

If you own a canary or live on a farm where chickens are raised, you may already know that birds have a very strange way of chewing their food.

Birds must swallow their food whole because they have no teeth.  Instead, the work of “chewing” is done by the gizzard, a special, muscular part of a bid’s stomach that grinds the food up.

Canaries and other birds that eat seeds and other hard food swallow small stones and grit along with the food.  This aids the grinding process and helps the bird digest the food.

It is sometimes easy to tell the kind of food a bird eats by the shape of its bill.

Finches and sparrows have short, strong bills for cracking the hard shells of seeds.

The long, spearlike bill of the heron and stork is ideal for jabbing fish and frogs.

And hawk has a sharp, hooked bill good for tearing apart the animals it catches for food.  – Dick Rogers
