Why is the gizzatd so hard and muscular?

Answer 1

The gizzard is a specialized muscular organ in birds that aids in digestion by grinding food, particularly hard seeds and grains. Its tough, muscular structure allows it to effectively crush and break down food, compensating for the absence of teeth. The gizzard's lining often contains small stones or grit that further assist in the grinding process, enhancing the bird's ability to extract nutrients from its diet. This adaptation is crucial for birds that consume tough or fibrous materials.
