Coprophagy is the behavior of a bird eating its own droppings or those of another bird.


An animal eating its own droppings or those of other animals.


Eating the feces is a normal behavior in dogs, but coprophagy in companion birds is rare and considered to be abnormal. The theory for this behavior in companion birds is that it is grounded in malnutrition. It is mostly seen in small parrots, such as budgerigars (parakeets) and cockatiels.


Put a grate on the cage bottom so the bird no longer has easy access to its droppings. Clean the cage more frequently, including the grate. Most importantly, the owner should address the possibility the bird has a nutritional deficiency, which may warrant a vet exam and change in diet.
