The posterior extension of the crop is called gizzard. It is a thick, muscular and triangular sac. Its wall is made up of tough, thick and circular muscles. The anterior part of the gizzard is called the armarium and the posterior part is the stomodium captica. Armarium wall folded longitudinally to form six leaf-like teeth. There is a pad-like layer behind the teeth. These leaves have fine bristles or hairs. Longitudinal folds contain bristles in deep pits. Gizzard teeth crush food. Bristle or Rome serves as strainer. Kapatika prevents reverse flow of food.
