In birds such as the budgie, and some members of the parrot family lack a gallbladder. The pancreas in birds is located near the small intestine. The first function of the pancreas is to neutralize acids that are found in the mixture passed on from the stomach. If this does not occur serious damage could occur to the intestine of the bird. Another major function of the pancreas is to produce insulin so that all the bird s cells are supplied with glucose.
Some birds have an appendix or cecum which helps in the digestion of grains and fibers.
This is not present is some members of the parrot family. Whatever does not get digested is passed through the single opening in the urogenital system known as the cloaca or vent. The waste is excreted in the form of bird droppings. Birds tend to make droppings often because they have such a high metabolism and eat often. If your bird is a seed eater its droppings should have a firm greenish or brown part, this is the feces, and the dropping should have a white pasty part, this is the urine.
