Get Answers to Bird Care Questions. Ask a Bird Specialist.
I'm sorry to see that no one has responded to your question earlier. Different experts come online at various times; I just came online and saw your question. Normally, when a bird is constipated with no other symptoms, feeding some fruit or another juicy food with fiber can help with the problem. If you haven't tried that already, I would do that first. However, when they also stop eating normally, as yours has, we may not be looking at simple constipation. Your bird may have an impaction or other blockage. He could have polyps or even a tumor preventing him form passing droppings.Under these circumstances, the only prudent thing to do is to see an avian vet. This link will take you to lists of vets that will help you find one near you:
In the meantime, dehydration is a risk. Buy some Pedialyte (yes, the kind for human infants). Until you can get to a vet, use a syringe to put some Pedilayte on the bottom of your bird's mouth once per hour. However, his condition may be serious, so try to see a vet as soon as possible.
