The food consumed is broken into smaller particles by mastication, the chewing action . From the pharynx and then through a connecting passage, called the esophagus, the food enters a relatively thin-walled storage chamber, or crop. The food vacuole initially contains both food and fluid. As birds do not urinate, they expel debris from uric acid in the form of a whitish, creamy paste.
