Why is my bird's poop bright green and watery after eating seeds?

Thank you for your question about Pecker, and I really appreciate you including pictures as they are very helpful! The droppings overall look very normal and appropriate, which is great. The urates are bright and white and the amount of urine is appropriate. I see what you mean about the difference in color - the lighter brown are less concerning to me than the darker colored ones. The reason for that is dark brown to black stools can be indicative of digested blood in the feces, also known as melena. In Pecker's case, with him being very new to you and you doing a diet switch (which is great, by the way - I recommend that budgies eat at least 50% pellets and then the rest of the diet can be made up of seed and produce items), I wouldn't worry too much because it may be due to the transition. However, if the dark stools continue, it would be advisable to take Pecker in for a wellness examination to have him (and his feces) evaluated. When you go, please make sure that you bring some of the dark feces, as your veterinarian can have it tested for occult (hidden) blood. They can also perform a thorough physical exam on him. Also, if anything about Pecker changes, including his attitude or appetite, this would also be reason to go into a veterinarian sooner rather than later. I would recommend regular weighing for him as well - you can do this by using a perch on top of a digital gram scale (found in the kitchen section of most department stores). I would recommend doing this 3 times per week. This will allow you to ensure he is not getting chunky or losing weight for some reason! Good luck with your new pet!

Thanks for reaching out about Meow. Possibly this is not an infectious problem, so antibiotics and anti-fungal might not help. With an all seed or heavy seed diet, fatty liver disease is possible which will not respond to the medications. Increasing protein and vitamins in the diet could help, as could an increase in dietary fiber. An avian veterinary visit is still recommended. Good luck.

Thanks for reaching out about Gigi and Villi and including a photo. Green feces could be the result of the green food but also in common with liver disease. One mild concern would be a condition call chlamydophilosis, which can also be communicable to other birds and people. A veterinary visit is recommended anyways for any new acquisitions, and this disease should be tested. Monitor for now but see a veterinarian if the condition persists. Good luck.

Thanks for reaching out about Pipo and including photos. The greenish stool is probably due to poor nutrition and possible liver disease. A comprehensive avian profile should be performed to analyze the white blood count and organ functions. Also a test for Psittacine Beak and Feather Disease is highly recommended. This is a virus, non-treatable, contagious to other birds. You need to get better nutrition into him, as apples are fiber and sugar. There are many commercially available baby bird feeding formulas, but as your veterinarian. Good luck.

Diet changes can affect the stool, and if you're feeding any extras in addition to the diet change, this could be causing the change you are seeing. It is also possible that his current diet is causing some minor GI upset if it changes immediately after eating and then returns to normal. Other issues such as internal parasites can also cause stool changes, so ruling out and treating for any parasites may be a good idea. Removing any extras such as fruit and veggies and providing only his balanced diet for a few days may also help him adjust and his stool return to normal. If the problem persists, or you see any other symptoms or changes such as reduced eating/drinking, lethargy, etc, then seeking vet care in person to rule out any more serious issues is best.

It looks normal but it is hard to tell 100% from this photo. I recommend you refer to this link/article: ( https://vcahospitals.com/know-your-pet/birds-abnormal-droppings ) If you are worried you can always have your vet do a fecal test/gram stain. The biggest way to keep your bird healthy is to feed the appropriate diet. I strongly suggest Lafeber diets. I don't know what you are feeding but many people default to seeds but that is not a good diet. ( https://lafeber.com/ ) Hope this helps. Best wishes.

If his behavior is unusual or any symptoms (such as changes to the stool and lethargic behavior) are worsening, seeking a vet visit in person is always best to rule out issues such as GI upset, illness, etc. Adding a little grit to the diet may also help better breakdown seeds in his food and allow him to digest/pass them more easily. Sometimes, parasites can look like seeds in the stool, so having a vet take a look and checking for any parasites may also be a good idea. As for fresh fruits and veggies, birds can sometimes be picky about what they eat. The best rule of thumb is to keep offering them until your bird finally gets curious enough to try it. He may find a new favorite!
