1. What is polyuria?

Polyuria is an increase in the urine component of bird droppings. Polyuria is often confused with diarrhoea. In polyuria there is increased liquid around the faeces and the faeces may be uncoiled.


2. Which component of the bird's droppings is the urine?

The droppings of birds consist of three components:

1) a central portion of dark solid faeces from the intestinal tract

2) white semi-solid urates made of urates from the kidneys

3) liquid urine from the kidneys


3. What is the cause of polyuria?

There are many causes of polyuria and often there is more than one problem.

Problems may include:

a)     Infectious Diseases

b)    Non-Infectious Diseases

       Nutritional deficiencies (especially all-seed diets)

       Anorexia (not eating) with increased drinking

       Poisons and toxins (heavy metal e.g. lead, zinc and copper; nicotine and plant poisons)


5. What diagnostic tests are needed on affected birds?

       Microscopic examination of faecal samples

       Urine analysis and blood tests to determine any organ damage (eg to the kidney and liver)

       Radiographs may determine the presence of tumours, swellings, eggs and heavy metal.


6. What is the treatment for polyuria?

Depending on the cause of the polyuria, treatment may involve antibiotics, medications for the kidneys or liver, or hormone injections. Changes in husbandry and diet are often necessary. In severe cases your bird will need to stay in hospital for several days while it is stabilised, and fluids and nutritional supplements administered.
