My bird has black liquid poop that turns the cage paper orange. Is it sick?

Updated on September 23rd, 2025

Pet's info: Bird | Unknown - Bird | Female

At the bottom of my bird's cage in the waste tray, I've found black liquid ish droppings. It Bleeds through the paper in the tray making it turn orange. I think it might be Harmony although I'm not sure. There is still normal poop so surely only one of my birds is sick? What does black poop that makes the litter tray turn orange mean? My parents say we can't take them to a vet and will just have to let them pass on. 1st pic is harmony, 2nd is Amico, 3rd is their poop tray. Thank you for helping.

Black, tarry, or bloody stool can indicate issues such as a GI bleed, digestive upset, or even parasites. In some cases, adding in too many fruits or veggies, or even different colored pellets within your bird's diet can also change the color of the stool, so if your bird is acting normal except for the stool change, stopping all treats and extras beyond regular food, checking for any pellets in the food that may be a similar color, and seeing if it clears up may help.

If your bird is ill in addition to the color change, such as acting listless, not eating or drinking, losing weight, etc, it would be best to have him seen by a vet, so it is a good idea to try and explain this to your parents. If your bird is ill, it is very cruel of them to not provide him with appropriate medical care, or to at least seek a humane euthanasia if he is suffering and they do not wish to treat the issue.

    All bird stool will have two components- a solid (the brown and green stuff you see) and a liquid (the white urea) as part of normal stool. However, if the stool has changed recently in color or consistency, it could indicate a number of things. Changes in diet or too many treats/snacks can affect the stool, and removing any treats for a few days while allowing for adjustment time to a new diet can help. Parasites and GI upset may also cause stool changes, and having a fecal exam done by your local vet is best to rule this out. If you are seeing any other signs of illness in addition to the stool change, making a note of them and having your vet examine Ethan in person is best.
