How does a parrots digestive system work?

Just like all birds, the parrot's digest tract consists of an esophagus, crop, proventriculus, gizzard, intestines, and cloaca. A parrot eats food, which goes down the esophagus and into the crop. From here food travels slowly down to the proventriculus which is the first part of the stomach and where juice from glands are released to break down food, The second part of the stomach is the Ventriculus or gizzard that contains grits to crush food particles. When food passes to the intestines more juices are secreted to continue the process of breaking down food. Waste is excreted through the cloaca.
