What is Polyuria?

However minor, any change to the appearance or frequency of your pet’s urine and fecal output may indicate a new or worsening health problem. Staying vigilant to such changes may make the difference between catching a minor issue before it becomes a more significant health problem. In the case of birds, their droppings are uniquely composed of three different components: a central “spot” of solid brownish or greenish feces from the intestinal tract, white semi-solid urates (a salt derived from uric acid) made up of urates from the kidneys, and finally, liquid urine from the kidneys.

In birds, the condition called polyuria refers to an increase in just the liquid component (urine) of the droppings. While sometimes confused with diarrhea, particularly by amateur bird fanciers and owners, the large volume of urine will alter the appearance of the feces by increasing the range of liquid around the solid matter. The droppings of a polyuric bird will still have a solid fecal component, while birds with diarrhea have a watery appearance to the fecal component. Overall, a fluctuation of any or all three components of bird droppings may indicate mild illness, toxicity, dietary issues, or else the developing or advancement of a serious health problem such as kidney disease or diabetes mellitus.

Such changes to a bird’s urine or feces may warrant a visit to an aviary veterinarian, who will likely recommend a range of diagnostic testing based upon the appearance of the droppings, as well as any other observable symptoms of potential illness in the bird. Some symptoms of concern will include lethargy, a ruffled appearance, weight loss and anorexia. If the bird presents with only mild changes to the liquid and solid components of the droppings, and shows no other physical or behavioral changes, serious illness is not likely. If, however, polyuria is persistent, or the condition recedes and then returns, or if new symptoms arise, immediate veterinary care is recommended.

In birds, the condition called polyuria refers to an increase in the liquid component (urine) of their droppings.

Symptoms of Polyuria in Birds

  • Increase in liquid component of bird droppings
  • Lethargy
  • Weakness
  • Tucking head beneath the wing
  • Exhaustion
  • Depression
  • Vomiting
  • Diarrhea
  • Blood in the stool
  • Lack of feces in droppings
  • Ruffled feathers
  • Anxious behavior
  • Loss of appetite
  • Anorexia

Causes of Polyuria in Birds

The cause of polyuria can take many forms. While a serious illness may be the underlying cause of the condition, the bird may instead be responding to factors such as a change in the diet, environmental stress, or the presence of toxins. Veterinarians often find that birds suffering from polyuria have more than one concurrent condition. Potential causes include:

  • Infectious diseases
  • Bacterial diseases
  • Chlamydophila
  • Parasitic infections
  • Nutritional deficiencies
  • Anorexia, with increased drinking
  • Liver disease
  • Poisons and toxins (heavy metals, nicotine, tobacco, inhalants, plant poisons)   
  • Diabetes
  • Hormonal imbalance
  • Reproductive disease
  • Kidney disease
  • Dietary changes – watery fruits and vegetables

Diagnosis of Polyuria in Birds

First, the veterinarian will conduct a physical examination of the bird. Be sure to explain when you first noticed changes to the droppings, and what kind of changes you noticed in the components. If the bird has been consistently suffering from polyuria, the vet may recommend a series of tests to search for the cause. He will be interested if the bird has recently been exposed to any other birds or new environments. 

Culturing the feces and/or cloaca to search for signs of infection is fundamental to the diagnosis.  A urinalysis may be administered, as well as a CBC (complete blood count) and serum biochemistry panel. Blood testing will search for any signs of toxicity. In more advanced cases, some owners may elect for x-rays and scopes, including endoscopy, to explore the intestines, liver, kidneys and pancreas. Tissue samples may be taken during the scope.

Treatment of Polyuria in Birds

Treatment will depend upon the outcome of the exam and testing, which may potentially include anatomical problems, disease, and secondary infections. In some cases, antibiotics or antifungal medications may be administered to treat the presence of infection. Medications may be given to treat damaged or low-functioning organs such as the kidneys. Modifications to the diet and environment may be necessary. 

In severe cases of polyuria, the bird may require inpatient treatment in order to stabilize.  IV or SubQ fluids and medications will be given in most cases, as well as nutritional therapy.

Recovery of Polyuria in Birds

Birds may become polyuric if placed on a diet rich in fruits and vegetables, or if changed to a new pellet. Birds that are stressed, such as moving to a new environment or encountering new people or animals, may temporarily become polyuric. The condition should not last beyond a day or two. Always avail the bird of plenty of fresh drinking water and a clean environment. Do not use litter of any kind to line the cage. Use only paper, and be sure to change the paper daily in order to discern any changes in the droppings. If improvement is not seen in the time allotted for recovery, report this to your veterinarian.

Watery poop no appetite.

My bird is a finicky eater and lately has only wanted to eat whole wheat pasta and a bit of egg and maybe a tiny bit of chicken. He also wants to eat seeds and I try to prevent him from doing this. But he is in a big room
With a few other little birds and he likes to go in their cages and eat budgie seed.

I have prevented this as much as possible. His energy level is fine and he seems happy. He hasn’t really lost any weight. But he has no appetite and watery stools on and off during the day. He has Had this for about 2 weeks now. He is in Harrison diet but he will it even touch the pellets anymore.

He’s drinking and does not seem
Lethargic and no blood in his stool. I am worried and don’t k ow if he’s just stressed or what’s going on here.

My Indian Ringneck has been plucking out his feathers from 6 months. We went to 3 diffeent vets but nothing really changed but his poop and behavior was normal. But from 3-4 days hs behavior has changed and is showing lack of activity and is almost always sleeping but is also whistling all the time. Since this behavior has started his poop has also become white curd like. There is little green solid part and he is pooping a lot more than usual. And when he poops, it is in large amount. Th vet suggested diarrhea but I think he is suffering from polyuria.

large amount of urine

Hi, Arlo is a 4 month old Pacific parrotlet and has produced a lot of urine since we got him at 8 wees old. We had him on an all organic seed diet and recently added in Harrison's pellets and fresh organic berries and kale or broccoli (per the vets advice). The vet tested his droppings for bacteria, parasites and viruses but the test came back normal. He plays and acts normal. Any ideas?

Watery poo

Hi. My cockatiel, Savior, has had polyuria for the past 3-4 months. I’ve taken him to the vet 3 times, has had multiple tests but all have come back fine. Last time, they said he was dehydrated and undernourished and kept him in for 2 days, then sent him home as a healthy bird. That was about a month ago. Savior continues to have watery droppings inconsistently and he drinks 3-4 gulps of water an hour. I know that this is very abnormal. But otherwise, he is playful and inquisitive and chirps. His diet is all seed, as I do not want to upset his stomach any further. He also tries to eat feathers and anything else he can find (which worries me because of potential blockages). He droppings are sometimes a lime green and sometimes grass green, which worries me because I know bright like green is a sign of kidney problems, but he has been tested for possibly kidney problems already, none were present. Savior is only 7 months old, and has had this issue for most of his life, without deterioration.
I’m very concerned but I’m not sure what to do. He has tried many medications including injections for heavy metal poisoning, probiotics and another medication it none work. Is his watery poop caused by drinking too much or is him drinking too much a result of dehydration because of watery poop?
I’m at a loss of ideas and money. Any help would be greatly appreciated.

“Increase appetite
“Watery dropping”
“Continuous polyuria
Increase weight”
Drasticcally change in poop

Ok, im in confusion again with Chiro, my wf lutino cockatiel. As i mention before we dont have vet that expert in avian, and i was rejected before when i went to vet clinic. Chiro has quite a continuous polyuria problem when i have him. Last polyuria problem i treated with triple C from vetafarm in dose of 5gr/L i gave it in 5 days. Those 5days of the medicated water, he got great poop, as in normal poop.
After 2 days of non medicated water, i gave him normal water with vitamin and probiotic, his polyuria was back again this morning.
I saw he drank a lot of water too.

Here the symptoms since he got his last polyuria :
- increased in appetite (last 5 months he was 83-86 gr , this morning he weighted 92gr , this month his weight is gradually increased from 88 to 92gr)
- no changes in his feather, eyes, beak, or nails
- his behaviour completely normal, except his appetite
- he turns one this months
- he have healthy poop when he was in medicated water
- he drinks a lot when the water was normal
- he eats a balance diet of fresh food, harrison pellet, pellet, nuts, his seeds mix, my organic super seeds (chia, quinoa, flax, amarant, pepitas, poppyseeds, etc).

Note: his room is quite warm around 28’ - 30’C .
Usually i put aircon so it went 25-26’ C.

I have some photos of the droppings, recent droppings and the cockatiel.
His poop this morning within 30 minutes — normal poop, watery, normal poop again

My 3 year old pet cockatiel has presented with PU/PD on and off, typically when she is molting, sometimes for no obvious reason. The periods last anywhere from days to weeks, but everything else is normal--weight, eating, playing, flying. Her diet consists of pellets (Harrison's Adult Lifetime). Could this be a sign of a hormonal imbalance? Would it even be treatable, considering the varying presentation? She laid two eggs about 4 months ago when we unknowingly made conditions more favorable (bath available 24/7, seeds for treats, she could reach her cage paper and was chewing). She was seen by an avian vet then and said to be in good health, and was uninterested in the eggs and has not laid since.

It may not be necessary to treat that condition since it happens intermittently. It may be hormone related, as most diseases that cause PU/PD don't fluctuate. If she seems healthy otherwise, you may be fine to monitor her for any signs of ill health, and have some lab work done if she is having any problems.

Tito may have a parasite or intestinal inflammation that needs to be treated, if his diarrhea has been going on for a month. Since I cannot examine him or look at a stool sample, it would be a good idea to have him seen by a veterinarian who can look at him and determine what might be going on, and get him treatment to resolve that diarrhea. I hope that all goes well for him!

Mitthoo may have parasites, a dietary problem, or an infectious disease. Unfortunately, without seeing her, I cannot determine what might be going on, but an examination by a veterinarian will allow them to see her, figure out what might be happening, and recommend any treatment that she may need.
