Unfortunately from what you describe, your bird is seriously ill. Please take him to an avian vet as soon as possible. Birds will instinctively hide signs of illness, so once they do appear ill, they have been sick for a while and they are quite ill. At this point every minute counts, so if necessary take him to an emergency clinic that sees birds. He most likely would succumb to his illness if you wait much longer.
